What is the best time tracking software for consultants?

Harvest is the best time tracking for consultants because it combines billable-hour tracking with invoicing in one tool. You track your time, then turn those hours into a client-ready invoice without exporting anything. For most consultants, that single workflow saves more hours than any other feature.

If Harvest isn’t the right fit, the runner-ups split cleanly by use case. Toggl Track is the pick for solo consultants who want the best automatic time tracking. Clockify makes sense for solo consultants on a tight budget. Deloitte-scale and global firms should look at a platform built for enterprise consulting time tracking.

This guide covers seven tools, but it starts with the four that matter most for boutique consultancies. Each one handles the full path from tracked time to paid invoice.

Why does Harvest win for most consultants?

Harvest wins because it treats billable and non-billable time as the core of the product, not an add-on. Every time entry is tied to a client, a project, and a task. That structure is what makes accurate invoicing for consultants possible later.

You can track time from a desktop timer, a mobile app, or a calendar integration with Google Calendar or Microsoft Outlook. Start a timer, pick the project, and the hours land in the right bucket. No manual time tracking, no end-of-week guesswork.

The invoicing side is where Harvest pulls ahead. You can create and send invoices straight from your tracked hours, with retainers and fixed-fee projects handled through project budgets. Consultants who bill hourly, by retainer, or on a hybrid model can run all three in one place.

Reporting is client-ready. You can generate detailed reports of hours by project, by team member, or by task, then share them. When a client asks “what did you do last month,” you have the answer in two clicks.

Pricing sits in the middle of the market, billed per user per month. For a 2–10 person firm, that cost is easy to justify once you stop losing billable hours to messy spreadsheets.

When is Toggl Track the better choice for automatic time tracking?

Toggl Track is best for solo consultants who forget to start timers. Its automatic time tracking watches what you’re working on and suggests time entries you can approve with one click.

That passive capture matters for consultants who move between clients all day. You don’t need to remember to switch timers. Toggl shows you where your time went, then you assign each block to a client or project.

It also has a generous free tier and apps for iOS and Android, plus desktop and browser extensions. The trade-off: invoicing is lighter than Harvest’s, so you’ll likely pair it with accounting software.

When does Clockify make sense for solo consultants on a budget?

Clockify is best for solo consultants who need real time tracking at zero cost. Its free plan is genuinely free, not a trial, and it covers unlimited users and projects.

Yes, Clockify is actually free for the core time tracking feature. You get a timer, manual entries, and basic reports without paying. Paid tiers add features like invoicing and project management tools, but many solo consultants never need them.

The catch is depth. Clockify’s reporting and billing features are simpler than Harvest’s, so it suits consultants who track hours and invoice elsewhere.

Which tool is best for enterprise and global consulting teams?

For enterprise and global teams, the right pick is a platform built for scale, not a solo app stretched thin. Look for role-based permissions, multi-currency invoicing, and compliance controls across regions.

These platforms handle employee time tracking across dozens of projects and teams, with approval workflows and audit trails. They also integrate with enterprise project management software and ERPs.

The trade-off is setup time and cost. If you run a boutique firm, you likely don’t need this tier yet. If you’re managing consultants across time zones, you do.

What is time tracking software for consultants?

Time tracking software for consultants is a tool that records hours by client, project, and task, then turns those hours into invoices. That last part is what separates it from a plain timer. A general productivity app tells you where your day went. Consulting time tracking software tells you what to bill, to whom, and at what rate.

Most tools in this category share the same core parts. You start a timer or type in hours. Each entry gets tagged to a client and project. From there, the software sorts every hour into billable and non-billable buckets, sends entries through approval if you have a team, and pushes the billable ones into an invoice or a financial report. Harvest, Toggl Track, and Clockify all follow this shape. So do larger platforms built for professional services teams.

The difference from generic project management tools comes down to money. A project management tool tracks tasks and deadlines. It may not know what an hour is worth. Time and billing software knows your rates, your clients, and what has already been invoiced. That link between hours and revenue is the whole point.

How does consultant time tracking differ from employee time tracking?

Employee time tracking usually answers one question: were you at work? It feeds payroll, attendance, and overtime rules. The unit that matters is the shift.

Consultant time tracking answers a different question: which client pays for this hour? The unit that matters is the time entry, tagged to a client or project. There is no shift to clock into. A consultant might bill three clients in one afternoon.

That is why consulting time tracking tools focus on billable versus non-billable hours, rates, and client-ready reports. Payroll tools focus on schedules and compliance. Some platforms do both, but they are built for different jobs.

What is the difference between billable and non-billable time in consulting?

Billable time is work you can charge a client for. That includes client calls, deliverable work, and research tied to a specific engagement.

Non-billable time is everything else: proposals, admin, training, internal meetings, and business development. It still matters. Tracking it shows your true effective rate, not just your headline rate.

Good software keeps these two separate without extra effort. You mark an entry billable or non-billable as you log it, and reports split the two. If half your week is non-billable, you want to see that clearly before you set next quarter’s rates.

How do time entries flow from projects and tasks to client invoices?

The flow has four steps, and most time tracking tools handle all of them.

First, you track time using a timer, a manual entry, or automatic time tracking that watches which apps and documents you use. Each entry lands on a project and task.

Second, entries roll up into hours by project and by client. This is where accurate time tracking pays off. Missing entries mean missing revenue.

Third, if you work with a team, entries go through approval. A manager reviews and locks them so nothing changes after billing.

Fourth, approved billable hours become an invoice. The software pulls the hours, applies your rate, and lets you create and send the invoice or export the data to your accounting system. Some tools also generate detailed reports on utilization and profitability so you can make informed decisions about which clients are worth keeping.

Why do consultants need time tracking software?

Consultants need time tracking software because their time is the product they sell. Every unbilled hour is lost revenue, and every guess at “how long did that take?” is a billing dispute waiting to happen. A good time tracking tool turns scattered notes and memory into a clean record of billable and non-billable hours, and that record feeds invoices, project decisions, and client trust.

Most consultants feel this pain in the same few places. You finish a busy week and can’t rebuild exactly where the hours went. You under-bill a fixed-fee project because you never saw the scope creep adding up. A client questions an invoice and you have nothing concrete to point to. Time tracking software fixes all three problems at once, and it does it without adding much work to your day.

How does accurate time tracking improve billable time management?

Accurate time tracking means you capture hours as they happen, not from memory on Friday afternoon. That alone recovers revenue most consultants quietly write off. Studies of professional services teams consistently find that manual time tracking loses a meaningful slice of billable hours — often 10% or more — because people round down, forget small tasks, or skip entries entirely.

The fix is a time tracking app that lives where you already work. Start a timer from your desktop and mobile devices, or let automatic time tracking watch which apps and documents you use and turn that activity into draft entries. You review the drafts, assign each one to a client or project, and you’re done. No stopwatch, no spreadsheet.

This matters most for billable versus non-billable separation. Admin, proposals, and internal meetings are real work, but they don’t go on an invoice. When your time tracking tool tags each entry as billable or non-billable, you can see how much of your week actually earns money. Many consultants are shocked to learn they spend 40% of their time on unpaid work. Once you see it, you can shift it.

How can time tracking data help you make informed decisions about project profitability?

Time tracking data turns gut feelings about project profitability into numbers you can act on. A fixed-fee project that felt fine can turn out to be paying you half your target rate once you divide the fee by actual hours. Without project time tracking, you’d never know until the next one goes the same way.

The key metric is effective hourly rate: total project revenue divided by hours worked. Time tracking software calculates it per project, per client, and per team member. You can then compare it against your target rate and spot the projects that drag it down.

That insight changes how you price and scope work. You might raise rates for clients who demand constant availability, add a change-order clause for scope creep, or drop the low-margin work entirely. Consultants who track time using a real tool make these calls with evidence. Those who don’t keep repeating the same unprofitable projects.

Project management features usually sit alongside the timer, so you can track and manage projects and tasks in one place. That means the hours, the budget, and the deadline all live in the same view — making it easy to catch a project drifting over budget before it’s too late.

How does time tracking provide client transparency and justify invoices?

Time tracking gives you client transparency, and that transparency justifies your invoices. When a client sees a detailed report — hours by project, task, and date, with notes on what was done — the invoice stops feeling like a black box. Questions drop sharply when the backup is right there.

Most time tracking solutions let you generate detailed reports and share them as PDFs or live links. Some let clients log in and see progress themselves. That level of openness builds trust, and trust makes clients less likely to nickel-and-dime your rates.

It also protects you in disputes. If a client claims a task took too long, you can show exactly when the work happened and what it involved. A timestamped record is far more persuasive than a verbal explanation.

Beyond defense, transparency is a sales tool. Send a clear, itemized report with every invoice and you look organized and professional. That’s often the difference between a client who haggles and one who renews without a second thought.

The bottom line: time tracking software pays for itself. Even a modest tool at a few dollars per user per month typically recovers far more in billable hours than it costs — often within the first week. For consultants, it isn’t overhead. It’s the system that makes sure you get paid for the work you already did.

How do consultants track billable vs. non-billable hours?

Consultants track billable vs. non-billable hours by tagging every time entry as one or the other, then running reports that show the split. That single habit is the most repeated feature across every tool in this review. It’s also the one that decides whether your invoices are right and whether you know which clients actually make you money.

What is the difference between billable versus non-billable time?

Billable time is work you can charge a client for. That means client calls, deliverable work, travel they agreed to pay for, and research tied to their project.

Non-billable time is everything else. Admin, proposals, business development, internal meetings, training, and invoicing all fall here. You still worked. You just can’t put it on an invoice.

The split matters because it tells you two things. First, your real effective rate: billable hours divided into total hours worked. Second, where your week actually goes.

Most consultants guess they spend 80% of their time on client work. The data usually says 50% to 60%. That gap is the whole reason to track.

Good time tracking tools handle this with a simple toggle or tag on each entry. You pick “billable” or “non-billable” when you log the time, and the tool does the math later. Some let you set a default per project, so client work starts as billable and internal projects start as non-billable.

One warning: don’t skip logging non-billable time. If you only track billable hours, you can’t see how much of your week is eaten by admin. You also can’t tell whether a retainer is profitable once you count the unbilled calls and emails that come with it.

How do you track time using a timer, manual entry, or automatic time tracking?

There are three ways to track your time, and most consultants end up using a mix.

Timer. You hit start when you begin a task and stop when you finish. This is the most accurate method because it captures real elapsed time, including the small interruptions you’d forget by 5 p.m. Harvest and Toggl Track both build their whole workflow around a start/stop button, and it’s available on desktop and mobile so you can run it from a phone between meetings.

Manual entry. You write down what you did after the fact. It’s fast for people who hate timers, and it works well for block scheduling. The tradeoff is memory. Studies on time recall show people round up and forget short tasks, so manual time tracking tends to undercount.

Automatic time tracking. The tool watches what you’re doing and suggests entries. Toggl Track is the standout here: it records the apps and pages you used, then you assign that time to a client or project. You review and confirm rather than build from scratch. It’s the best option for consultants who forget to start a timer.

Whichever method you pick, tie entries to a client or project at the moment you log them. Reconstructing a week later is where billing errors come from.

A few practical habits help:

• Start the timer before you open the client’s file, not after.
• Round to six-minute increments (0.1 hour) so invoices stay clean.
• Review yesterday’s entries each morning while they’re fresh.
• Use the mobile app for calls and travel so nothing leaks.

The goal isn’t a perfect record. It’s a record good enough to bill from and learn from.

How do you categorize time entries by client or project and task?

Categorizing is where consultant time tracking earns its keep. The standard structure has three levels: client, project, and task.

Client is who pays. Project is the engagement or matter. Task is the specific piece of work, like “draft report” or “discovery call.”

Here’s why all three matter. Client-level totals feed your invoices. Project-level totals show whether the engagement is on budget. Task-level detail shows where the hours went inside the project, which is what you need when a fixed-fee job runs long.

Set this up once and it pays off all year:

1. Create the client record first, then attach projects to it.
2. Add a small, fixed task list per project. Five to eight tasks is plenty. Long lists don’t get used.
3. Mark each project billable or non-billable by default.
4. Set a billable rate at the client or project level so the tool calculates amounts automatically.
5. Tag entries as you go, not in a Friday cleanup session.

Most time tracking software for consultants also connects to invoicing. Harvest, for example, lets you pull tracked hours straight into an invoice and create and send it without retyping anything. That link between tracking and billing is the feature to check before you commit to a tool.

Reports are the payoff. You want hours by project, hours by client, and a billable vs. non-billable ratio you can view by week or month. That’s the data that tells you which clients to keep and which to raise rates on.

If you use project management tools alongside your tracker, look for one that combines both. A project management solution with built-in time tracking keeps tasks, hours, and invoices in one place, so you’re not copying data between systems. That’s less admin, fewer errors, and a cleaner path from tracked time to paid invoice.

What features should consultants look for in time tracking software?

The feature that matters most is clean billable vs. non-billable separation. If a tool can’t split client work from admin work without extra steps, skip it. After that, check invoicing, reporting, and integrations.

Here’s what to look for, in order of importance.

Billable vs. non-billable categorization

Every time entry should have a billable toggle you can flip in one click. You should also be able to mark a whole project as billable by default, so you only change the entries that aren’t.

This matters because most consultants lose money in the same place: untracked admin time. Proposals, emails, and internal meetings eat hours that never reach an invoice. When you tag those hours as non-billable, you can see exactly how much of your week goes to unpaid work.

Good tools also let you set a default rate per client or project. That way, billable versus non-billable sorting happens as you track, not hours later when you try to remember what you did.

Invoicing and billing integration

Tracking and billing should live in the same tool. If you track in one app and invoice in another, you’ll retype hours every month, and retyping is where errors creep in.

Look for a tool that turns approved time entries directly into an invoice. You want to pick a client, pull in unbilled hours, and send. Some tools also handle retainers, so you can draw down a prepaid block of hours and show the client their remaining balance.

If your accountant uses QuickBooks or Xero, check that the tool connects. A clean export beats a shoebox of PDFs every time.

Reporting and analytics

Reports are where time tracking data earns its keep. At minimum, you need three views: hours by project, hours by client, and utilization rate.

Utilization is the share of your working hours that are billable. A solo consultant usually targets 60% to 70%. If yours sits at 40%, you have a pricing problem or a scope problem, and the report tells you which.

Profitability reports go one level deeper. They compare what you billed against what the work cost you in time. That’s how you find the client who feels busy but quietly loses money.

You should also be able to generate detailed reports you can hand to a client. A clean summary of hours by task builds trust and kills invoice disputes before they start.

Mobile and multi-platform access

Consultants work in airports, client offices, and coffee shops. If you can only track time at your desk, you’ll lose entries.

Look for iOS and Android apps that sync in real time with the desktop version. A good mobile app lets you start a timer, add a note, and assign the entry to a project in under ten seconds. Some tools even offer home screen widgets or Apple Watch timers for one-tap tracking.

Desktop and mobile should show the same data. If your phone and laptop disagree about your hours, the tool is creating work instead of saving it.

Integration with project management and accounting tools

Your tracker shouldn’t be an island. The more it connects to, the less you copy and paste.

The integrations that matter most for consultants:

• Accounting: QuickBooks, Xero, and FreshBooks, so invoices flow straight into your books.
• Project management: Asana, Trello, Jira, and Monday.com, so tasks and hours stay linked.
• CRM: Salesforce, HubSpot, and Pipedrive, so you can see time spent per deal or client.
• Calendars: Google Calendar and Microsoft 365, so meetings become time entries automatically.

Calendar sync is underrated. When your tracker reads your calendar, it can suggest entries for meetings you just finished. That’s automatic time tracking without installing monitoring software.

Ease of use and user adoption

The best time tracking tool is the one you actually open. A tool with every feature but a clunky interface will sit unused by week two.

Test this before you buy. Start a timer, stop it, and edit the entry. If that takes more than three clicks, keep looking. Manual time tracking only works when it’s fast enough to do in the moment.

For small firms, ease of use decides whether your team logs hours at all. A tool nobody uses produces no data, no invoices, and no insight. Free trials exist for exactly this reason. Run one for a week on real client work before you commit.

Does the tool offer project budgeting and profitability tracking?

Yes, and this is a feature to verify, not assume. Set a budget in hours or dollars per project, then watch a progress bar as the work burns through it.

When a project hits 80% of budget, you want a warning, not a surprise. That early signal lets you talk to the client about scope before you’ve given away ten free hours.

Profitability tracking pairs with budgeting. It shows your effective hourly rate per project after all time is counted, billable and not. Consultants who review this monthly make better decisions about which projects to take and which rates to charge.

Can you track time on desktop and mobile with iOS and Android apps?

Yes, any serious tool offers both. Desktop apps for Windows and macOS usually include a menu bar timer, so tracking is one click away while you work.

Mobile apps handle the rest. Start a timer from your phone between meetings, or add a manual entry at the end of the day. Offline mode helps too. If you track time on a plane, the entry should sync once you land.

Check that the apps share one account and one set of projects. Splitting your data across platforms defeats the purpose.

Does the software integrate with Google Calendar and Microsoft 365?

Most leading tools do, but the depth varies. Basic sync shows your calendar inside the tracker. Better sync turns calendar events into draft time entries you approve with one tap.

This matters for consultants because meetings are billable work that’s easy to forget. If your 10 a.m. client call auto-appears as a draft entry, you’ll bill it. If it doesn’t, that hour vanishes.

Microsoft 365 integration often extends to Outlook calendar and Teams. If your clients live in Microsoft’s world, confirm the tool plays nicely with it before you buy.

How does the tool handle multi-currency and tax rules for consulting billing?

If you bill overseas clients, this can make or break a tool. You want to set a currency per client, so a UK client sees GBP and a US client sees USD on their invoice.

The tool should store rates in the original currency and convert only at invoice time, using a rate you control. That keeps your books clean and avoids arguments about exchange rates.

Tax handling matters too. Many tools let you add VAT, GST, or sales tax lines to invoices, either per client or per invoice. Some calculate it automatically based on the client’s country.

Check what your tool does not handle. Complex tax rules usually belong with your accountant, so look for clean exports they can work from rather than expecting the tracker to do everything.

The 7 best time tracking software for consultants in 2026

Harvest is the best overall time tracking software for consultants because it handles billable-hour tracking and invoicing in one tool. Toggl Track is the best runner-up for automatic time tracking and integrations. Clockify is the best free pick for solo consultants. Deltek and similar platforms fit enterprise and global teams.

Below are the seven tools that earned a spot on this list. Each one gets the same breakdown: features, pricing, pros and cons, and ratings. I split them into standalone trackers and all-in-one platforms so you can match a tool to how your practice actually runs.

1. Harvest: Best for simple time tracking and invoicing

Harvest is best for consultants who want to track billable hours and send invoices without leaving one app. It has been around since 2006, and that age shows in a good way. The product is calm, focused, and hard to break.

Features. Harvest centers on a clean timer. You pick a client, pick a project, pick a task, and hit start. A keyboard shortcut starts and stops the timer from anywhere on your desktop. That sounds small. For consultants who bill in six-minute increments, it matters a lot.

The tool separates billable and non-billable time at the project level. You set a project as billable, set an hourly rate, and every time entry rolls toward that rate. Non-billable work like proposals and admin gets its own project with no rate. At the end of the month, you filter by client and see exactly how many billable hours you logged.

Invoicing is the real draw. Harvest pulls tracked hours straight into an invoice. You can round time up or down, apply a discount, add tax, and send the invoice by email. Clients can pay online through Stripe or PayPal. Harvest also tracks retainer budgets, so you can see how much of a prepaid block of hours a client has burned through. That single feature saves consultants from the awkward “you’re out of retainer hours” email.

Reports cover hours by project, hours by team member, and budget spend. You can also pull a report that shows uninvoiced amounts, which is the fastest way to catch billable work you forgot to bill.

Pricing. Harvest runs on per-user pricing. The free plan covers one user and two projects, which is fine for testing but tight for real work. The paid plan is $12 per user per month when billed yearly, or $13 month-to-month. There is a 30-day free trial and no credit card required to start. A 10% discount applies if you pay for a full year up front.

Pros. Invoicing and time tracking live in one place. The interface is genuinely easy to use. Retainer tracking is built in. Integrates with QuickBooks, Xero, Asana, Trello, and Google Calendar. Mobile and desktop apps both work well.

Cons. No automatic time tracking. You have to start the timer yourself. Reporting is solid but not deep. No built-in profitability view by team member without exporting data.

Ratings. Ease of use: 9/10. Features: 8/10. Value: 9/10. Best for: solo consultants and small firms that bill hourly and want invoicing handled.

2. Toggl Track: Best for automatic time tracking and integrations

Toggl Track is best for consultants who forget to start a timer. It watches what you do and suggests time entries for you. That one feature changes how much billable time you actually capture.

Features. Toggl Track’s headline feature is its automatic tracker. The desktop app records which apps and websites you used and for how long, then shows you a timeline. You drag blocks of time onto a project and turn them into billable entries. If you spent 40 minutes in a client’s Google Doc and forgot to track it, Toggl catches it.

The tool also has a solid manual timer, a one-click start button, and a browser extension. You can track time from a browser tab, a desktop app, or a phone. Idle detection asks if you stepped away, so you don’t bill for time you spent making coffee.

Toggl Track handles billable and non-billable rates per project. You can set a default hourly rate and override it per client. Reports show total hours, billable hours, and billable amount. You can group by client, project, task, or team member. The reporting is stronger than Harvest’s out of the box.

Integrations are where Toggl Track pulls ahead. It connects to over 100 tools, including Asana, Jira, Trello, Notion, Google Calendar, and Microsoft Outlook. There is also a public API, so teams with a developer can push time data anywhere.

One gap: Toggl Track does not do invoicing. You track time, export it, and bill through a separate tool. For consultants who already invoice through QuickBooks or FreshBooks, that is fine. For those who want one app, Harvest wins.

Pricing. Toggl Track has a free plan for up to five users with basic tracking. The Starter plan is $9 per user per month billed yearly, or $10 month-to-month. The Premium plan is $18 per user per month yearly, or $20 monthly, and adds billable rates, project estimates, and time audits. There is a 30-day free trial on paid plans.

Pros. Best-in-class automatic time tracking. Huge integration list. Strong reporting. Free plan covers small teams. Works on iOS and Android.

Cons. No invoicing. The free plan limits billable rate features. Some users find the timeline view busy at first.

Ratings. Ease of use: 8/10. Features: 9/10. Value: 8/10. Best for: consultants who lose track of time and want it captured automatically.

3. Clockify: Best free option for solo consultants

Clockify is best for solo consultants who need real time tracking at zero cost. It is the most generous free plan in this category, and it is not a stripped-down demo.

Features. Clockify’s free plan includes unlimited users, unlimited projects, and unlimited tracking. That is unusual. Most tools cap the free tier at one or two users. Clockify does not.

You get a manual timer, a timesheet view, and a calendar view. You can track time by client, project, and task. Billable and non-billable hours are separated, and you can set an hourly rate per project. Reports include summary, detailed, and weekly views, plus a billable amount report.

The paid tiers add features consultants often want later. The Standard plan adds billable rates on the free plan, team tracking, and time off. The Pro plan adds project budgets, profitability tracking, and invoicing. The Enterprise plan adds scheduling and audit logs.

Clockify also has a desktop app with idle detection and a Chrome extension. It integrates with Google Calendar, Microsoft 365, Asana, Trello, and Jira. The mobile apps for iOS and Android are solid.

The catch is polish. Clockify’s interface is busier than Harvest’s, and some settings hide behind menus. It also shows ads for its paid plans inside the free version. For a solo consultant watching every dollar, that trade is usually worth it.

Pricing. Free forever for unlimited users and projects. Standard is $4.99 per user per month billed yearly, or $6.99 monthly. Pro is $8.99 per user per month yearly, or $10.99 monthly. Enterprise is $14.99 per user per month yearly. There is a 7-day free trial on paid plans.

Pros. Genuinely free for solo use. Unlimited projects and clients on the free plan. Invoicing available on Pro. Good integrations. Works on mobile and desktop.

Cons. Ads in the free version. Interface takes time to learn. Some advanced reports sit behind paid tiers.

Ratings. Ease of use: 7/10. Features: 8/10. Value: 10/10. Best for: solo consultants and new practices that need to keep costs at zero.

4. FreshBooks: Best for invoicing-first consultants

FreshBooks is best for consultants who think of themselves as billing first and tracking second. It is accounting software with time tracking built in, not the other way around.

Features. FreshBooks tracks time with a timer or manual entry. You assign entries to a client and a service, then turn them into an invoice with one click. The invoicing side is deep: recurring invoices, late fees, payment reminders, and online payments through Stripe and PayPal.

The tool handles expenses too. You can log a client lunch or a software subscription, mark it billable, and add it to the same invoice as your hours. For consultants who pass through costs, that saves a step.

Reports cover profit and loss, expenses, and unbilled time. The unbilled time report is the one to watch. It shows every tracked hour that has not hit an invoice yet.

FreshBooks integrates with Google Workspace, Gmail, and 100+ other apps through its app store. Mobile apps for iOS and Android let you track time and send invoices from your phone.

The tradeoff is price. FreshBooks costs more per user than Harvest or Toggl Track, and its time tracking is simpler than a dedicated tracker. If you bill by the hour and want the invoice to do the heavy lifting, it fits. If you need detailed project time reports, look elsewhere.

Pricing. Lite is $19 per month for five billable clients. Plus is $33 per month for 50 clients. Premium is $55 per month for unlimited clients and adds project profitability. Prices drop with yearly billing. There is a 30-day free trial.

Pros. Excellent invoicing. Expenses and time on one invoice. Good mobile apps. Strong accounting reports.

Cons. Higher price. Client limits on lower tiers. Time tracking is basic compared to dedicated tools.

Ratings. Ease of use: 8/10. Features: 8/10. Value: 7/10. Best for: consultants who invoice often and want accounting and time in one place.

5. Hubstaff: Best for teams that need proof of work

Hubstaff is best for consulting firms that bill clients who want proof of hours worked. It tracks time with screenshots, activity levels, and GPS, which some clients demand.

Features. Hubstaff runs a timer that can capture screenshots at set intervals, track keyboard and mouse activity, and log URLs visited. You can turn each of these off, but the point of Hubstaff is that they exist. For consultants on fixed-fee contracts who need to justify hours, that data is useful.

The tool supports manual time entry, timesheets, and approvals. You can set billable rates per project and per team member. Reports show hours, activity, and billable amounts. Payroll and invoicing integrations connect to PayPal, Payoneer, and Wise.

Hubstaff integrates with Asana, Trello, Jira, GitHub, and QuickBooks. It has desktop apps for Windows, Mac, and Linux, plus iOS and Android apps. The Linux support is rare in this category.

The downside is trust. Screenshots and activity monitoring can feel heavy for a small consulting team. If your clients do not ask for proof, you may not need this. If they do, Hubstaff is the strongest option here.

Pricing. Free plan for one user with basic tracking. Starter is $7 per user per month billed yearly, or $9 monthly. Pro is $12.50 per user per month yearly, or $15 monthly, and adds screenshots and activity tracking. Enterprise is custom. There is a 14-day free trial.

Pros. Screenshots and activity tracking. Linux support. Strong team reporting. Good integrations.

Cons. Monitoring features can feel invasive. Interface is dense. Free plan is very limited.

Ratings. Ease of use: 7/10. Features: 8/10. Value: 7/10. Best for: consulting teams whose clients require proof of hours.

6. TimeCamp: Best for automatic categorization

TimeCamp is best for consultants who want automatic time tracking with less setup than Toggl Track. It learns which apps and sites belong to which client and sorts them for you.

Features. TimeCamp runs in the background and records your activity. It uses keywords in window titles and URLs to guess the client or project. Over time, it builds rules so future entries land in the right place. You can also set up manual rules if you want control.

The tool has a timer, a timesheet, and a calendar view. It supports billable and non-billable rates, project budgets, and invoicing on higher tiers. Reports include attendance, budget, and billable time. There is a computer activity report that shows how much time went to productive versus unproductive apps.

TimeCamp integrates with Trello, Asana, Jira, Google Calendar, and Microsoft 365. It has desktop apps for Windows, Mac, and Linux, plus iOS and Android. The free plan covers unlimited users but limits tracking to one project.

The learning curve is the main issue. The automatic rules take a week or two to get accurate. Until then, you will fix entries by hand. Once trained, it runs quietly.

Pricing. Free plan for unlimited users with one project. Starter is $2.99 per user per month billed yearly, or $3.99 monthly. Basic is $5.99 per user per month yearly, or $7.99 monthly. Pro is $9.99 per user per month yearly, or $10.99 monthly, and adds invoicing and budgeting. There is a 14-day free trial.

Pros. Automatic categorization. Low entry price. Linux support. Budget and invoicing on Pro.

Cons. Rules need training. Interface is dated in places. Free plan is very limited.

Ratings. Ease of use: 7/10. Features: 8/10. Value: 8/10. Best for: consultants who want automation without a big setup.

7. Deltek: Best for enterprise and global consulting firms

Deltek is best for large consulting firms that need time tracking tied to project accounting, resource planning, and multi-currency billing. It is not a small-practice tool.

Features. Deltek’s products, including Deltek Vantagepoint and Deltek Maconomy, handle time and expense entry, project accounting, billing, and resource planning in one system. Consultants enter time against projects and phases. The system routes entries through approval workflows and pushes them into invoices and financial reports.

Multi-currency and multi-tax support are built in. A firm with offices in three countries can bill in three currencies and apply local tax rules. Revenue recognition follows accounting standards, which matters for firms that report to investors or banks.

Reporting is deep. You can pull utilization by team member, project profitability, and backlog reports. The data feeds into forecasting so partners can see how full the pipeline is.

Deltek integrates with Microsoft 365, Salesforce, and major ERP systems. Mobile apps exist but are less polished than the consumer tools on this list.

The cost and setup are high. Deltek runs on custom pricing, usually with an annual contract and an implementation fee. It takes weeks to roll out. For a 200-person firm, that is fine. For a solo consultant, it is overkill.

Pricing. Custom quotes only. Expect annual contracts and implementation costs. No free plan. Demos are available on request.

Pros. Full project accounting. Multi-currency and multi-tax. Strong reporting and forecasting. Scales to large firms.

Cons. Expensive. Long setup. Not built for solo consultants. Mobile apps lag behind.

Ratings. Ease of use: 5/10. Features: 10/10. Value: 7/10 for large firms, 2/10 for solo. Best for: enterprise and global consulting teams.

How to pick between these seven

Match the tool to your billing style. If you bill hourly and send invoices yourself, Harvest is the cleanest fit. If you lose track of time, Toggl Track’s automatic tracking pays for itself. If budget is the blocker, Clockify’s free plan is real. If you bill through an accountant, FreshBooks keeps time and books together. If clients demand proof, Hubstaff delivers it. If you want automation with less setup, TimeCamp learns your patterns. If you run a large firm, Deltek handles the complexity.

One last note on the free question. Clockify is actually free for unlimited users and projects, and that is not a trial. Harvest, Toggl Track, and Hubstaff also have free plans, but each caps users or projects. Read the limits before you commit.

How to choose the right time tracking software for your consulting firm

The criterion that matters most is billable versus non-billable separation. If a tool cannot cleanly split client work from admin, proposals, and business development, it will not work for consulting. Retainer handling and client-ready reporting come next. Get those three right and the rest is detail.

Match the tool to your team size

Team size decides how much software you need. A solo consultant needs speed. A 50-person firm needs control.

Solo consultants. You need a time tracking app that takes seconds to start. A timer, a client list, and an invoice button cover most of it. Skip tools with approval chains and admin roles. You will never use them.

2-10 people. This is where shared clients and projects appear. You need one workspace everyone can see, so two people do not bill the same hour twice. Look for simple permissions and a shared client list.

10-50 people. You now need roles, approvals, and utilization reports. Managers need to see hours by project without asking. Project budgeting matters too, because one overrun can eat a month of profit.

50+ people. You need enterprise controls: single sign-on, audit logs, multi-currency, and an API. Global firms also need tax rules by region. This is Deltek territory, and the price reflects it.

Match the tool to your billing model

Your billing model decides which features you actually need. Hourly, retainer, and fixed-fee work each stress a different part of the tool.

Hourly billing needs accurate time entries tied to a rate. The tool must carry that rate from the time entry to the invoice without retyping.

Retainer billing needs a running balance. You bill a set amount each month, then draw down hours against it. The tool must show hours used and hours left per client.

Fixed-fee billing needs budget tracking, not rates. You care about hours spent versus hours estimated. Profitability per project is the number that matters.

If you mix all three, pick a tool that handles each without workarounds. Most time tracking tools do hourly well and retainer poorly.

Six questions to ask every vendor before signing

Ask these before you pay. The answers will separate the tools that fit from the ones that do not.

1. How does it separate billable and non-billable time? You want a field on every time entry, not a tag you add by hand.

2. How does it handle retainers? Ask for a live demo of a retainer drawdown. If the rep hesitates, that is your answer.

3. What do client reports look like? Ask to see a real report, not a screenshot from the marketing site. You need hours by project, by person, and by task.

4. What integrations ship on day one? Google Calendar and Microsoft 365 are table stakes. So is your accounting tool. Check the list before you commit.

5. What does support cost, and what are the hours? A cheap tool with email-only support can cost you a client invoice.

6. What happens to my data if I leave? You need a full CSV export of every time entry. No export, no deal.

How do you match the tool to your billing model (hourly, retainer, fixed-fee)?

Start by writing down how you bill today. Most consultants bill two or three ways at once, and that mix drives the choice.

For hourly work, confirm the tool stores a rate per client and per person. Then confirm it pushes those hours into an invoice without a spreadsheet in between. Harvest does this in one flow.

For retainers, test the drawdown view. You want to see hours used this period, hours remaining, and a warning when you cross the limit. Few tools do this well, so test it early.

For fixed fees, test budget alerts. Set an estimate, log hours, and see if the tool warns you at 80 percent. If it does not, you will find out at the end, when it is too late.

One more test: run a fake month with all three models. It takes an hour and saves a year of frustration.

What are the six questions to ask every vendor before signing?

The six questions above are the short list. Here is how to use them in a demo.

Send the questions before the call. A vendor who answers in writing is a vendor who knows the product. A vendor who dodges is telling you something.

During the demo, ask them to show, not tell. Ask for a live retainer drawdown. Ask for a real client report. Ask them to export a CSV on the call.

Then ask about the price model. Most tools charge per user per month, and the real cost shows up at renewal. Ask what the price is at your team size in year two.

Finally, ask for two references in consulting. Professional services teams use these tools differently than software teams do. A reference from a law firm or agency tells you more than a logo wall.

How do you test time tracking software before committing?

Use the free trial, but test it like a real week, not a demo. Free plans from Harvest, Toggl Track, and Hubstaff all cap users or projects, so read the limits first.

Day one: set up two clients and three projects. Log a full day of real work. Time yourself. If setup takes more than 30 minutes, the tool is too heavy for a solo practice.

Day two: log a non-billable day. Track admin, email, and a proposal. See how the tool handles time that never reaches an invoice.

Day three: run a report and send it to yourself as a client would see it. If the report needs cleanup in a spreadsheet, note that cost.

Day four: test the mobile app on iOS or Android. Log an hour from your phone. Check that it syncs.

Day five: export everything to CSV. If the export is clean, you can leave anytime. That is the real test of any time tracking tool.

How do consultants handle retainers and fixed-fee projects in time tracking software?

Retainers and fixed fees break the simple “hours times rate” math, so the tool has to track time for visibility while billing a flat amount. The fix is to separate tracking from billing inside the software. You still log every hour, but you change what the invoice pulls from.

Most consultants run at least one of four models: retainer with rollover, fixed-fee project, milestone billing, or a mix of hourly and value-based pricing. Each needs a slightly different setup. Here is the practical workflow for each one.

How do you set up retainer hours with rollover in time tracking software?

A retainer is a block of hours a client prepays each month. Rollover means unused hours carry into the next month instead of expiring.

Set this up as a project with a monthly hour budget, not a dollar budget. In Harvest, you create the project, set the budget type to hours, and mark it recurring. Each month the budget resets. To handle rollover, carry the leftover hours forward yourself or use a tool like Toggl Track that lets you adjust the budget mid-cycle.

Track every hour against that project, billable and non-billable. At month end, run a report showing hours used versus hours available. If the client used 18 of 20 retainer hours, the 2 leftover hours roll to next month. If they used 24, you bill the extra 4 at your hourly rate.

The key move: keep the retainer as its own project so retainer hours never mix with project work. This makes the rollover math clean and gives you a client-ready report in one click.

Watch the overage. A retainer client who blows past their hours every month is really an hourly client. Your time tracking data will show that pattern in two or three months.

How do you track fixed-fee projects and change orders?

A fixed-fee project bills one price no matter how long it takes. You still track time, but for profitability, not billing.

Create the project, set a fixed fee as the budget, and log all hours as billable. The software will show you hours worked against the fee. If you quoted $8,000 and you have logged 60 hours at a $150 target rate, you are at $9,000 of “value” — you are losing money.

This is where change orders matter. When a client asks for work outside the original scope, create a separate project or task for it. Do not log change-order work under the main project. That way your original project stays profitable on paper, and the change order gets billed on its own.

Name change orders clearly: “Website Redesign — Phase 2 Add-On.” Log time there, then invoice it separately. Tools like Harvest and Toggl Track both let you attach a flat fee to a task, so the change order bills as a set amount even though you tracked real hours.

The rule: fixed-fee projects need a budget alert. Set it at 80% so you get warned before you blow the fee.

How do you handle milestone billing and mixed hourly and value-based pricing?

Milestone billing splits a fixed fee into stages. You bill 30% at kickoff, 40% at delivery, 30% at sign-off. The project fee never changes — only the timing of invoices does.

In your time tracking tool, set up the project as fixed-fee, then create tasks for each milestone. Log time under the milestone task it belongs to. When a milestone is done, generate an invoice for that portion. Harvest handles this well because you can invoice a percentage of a project budget.

Mixed pricing is the common case for consultants. One client pays hourly, another is on retainer, a third is fixed-fee. The tool has to support all three at once without forcing you into one model.

The workflow: use project-level billing settings. Hourly projects bill by tracked time. Retainer projects bill by the block. Fixed-fee projects bill by the fee. Milestone projects bill by stage. Keep each client’s work in its own project, and the software sorts the billing for you.

For value-based pricing, where you charge for outcomes rather than hours, track time anyway. You will not bill from it, but you need it to see your real effective rate. If you charge $20,000 for a project that takes 200 hours, your effective rate is $100 an hour. That number tells you whether your pricing works.

A few practical tips across all four models:

• Tag every time entry with the right project and task. Clean tags make reports usable.
• Run a profitability report monthly, not just at invoice time. You want to catch a losing project early.
• Use automatic time tracking for retainer clients so you never forget a billable hour.
• Export time tracking data to your accounting tool so invoices match your books.

The best time tracking software for consultants handles all four models without workarounds. Harvest and Toggl Track both do. Clockify handles them on paid plans. If your tool forces you to fake a fixed fee as hourly, it is the wrong tool.

Set up one retainer client and one fixed-fee client this week. Run them through a full billing cycle. You will learn more in one month than in any demo.

How do you sync time tracking data with QuickBooks or Xero without double entry?

The fix is simple: connect your time tracker to QuickBooks or Xero once, then let approved time entries flow straight into invoices. No retyping. No copy-paste.

Most tools do this through a native integration or a Zapier-style bridge. Harvest and Toggl Track both push billable hours to QuickBooks Online and Xero. The xero time tracking integration works the same way: you link the accounts, map clients to contacts, and pick which service items your hours should bill against.

Here is the part people miss. You only sync approved time. If a junior consultant logs 40 hours and a partner has not reviewed it, that time should not hit your books yet. Set an approval step first. Then sync.

Once synced, the invoice builds itself from your time entries. You pick the date range, choose the client, and the tool pulls in every billable hour with its task description. You review, adjust if needed, and send. The invoice lands in QuickBooks or Xero as a real transaction, not a PDF you typed by hand.

How do you handle multi-currency invoicing and tax rules when syncing time entries?

Multi-currency is where syncing gets messy. Your time tracker might log hours in one currency while your accounting software holds the client in another.

Set the currency at the client level, not the invoice level. That way every time entry inherits the right currency before it ever reaches QuickBooks or Xero.

Tax rules add another layer. Consulting services are taxed differently depending on where the client sits. A US client in another state may owe no sales tax on services. A UK client may fall under VAT. An EU client may trigger reverse-charge rules.

Your accounting software should own the tax logic, not your time tracker. Let QuickBooks or Xero apply the tax code when the invoice is generated. Your time tracker’s only job is to deliver clean hours to the right line item.

If your tool lets you set tax rates per client, use that as a backup. But treat the accounting side as the source of truth.

What are common reconciliation pitfalls when syncing time tracking data with accounting software?

The biggest pitfall is duplicate invoices. This happens when someone syncs time entries, then also creates the invoice by hand. Now the client gets billed twice.

Fix it by making the sync the only path to an invoice. One source, one invoice.

The second pitfall is orphaned time. A consultant logs hours under a client name that does not match the contact in QuickBooks. The sync fails silently. Those hours never get billed.

Match your client names exactly across both systems before you sync anything. Do this once, at setup, and you avoid months of cleanup.

The third pitfall is edited time after invoicing. Someone changes a time entry that already flowed into a sent invoice. Now your books and your tracker disagree.

Lock time entries once they are invoiced. Most tools let you do this. Turn it on.

How do you walk through an end-to-end billing workflow from time entry to invoice?

Here is the full path, start to finish.

A consultant tracks time using a timer or manual entry. Each entry gets tagged with a client, a project, and a task. Billable or non-billable gets marked at this step.

The entry goes to an approver. They check it against the project scope and approve or send it back.

Approved hours sit in a billing queue. At the end of the month, or when the project hits a milestone, you pull that queue into a draft invoice.

You review the draft. You adjust descriptions, confirm rates, and check the currency and tax code.

You send the invoice. It syncs to QuickBooks or Xero as a live transaction. Your books update. Your client gets a clean, itemized bill.

Then you reconcile. Compare the hours billed against the hours tracked. If they match, you are done. If they do not, find the orphaned entries and fix them before the next cycle.

Run this loop once with a real client. The friction points show up fast, and they are always in the same two places: client name mismatches and unapproved time. Fix those two and the rest runs itself.

How do you present time tracking data to clients to build trust and justify invoices?

Trust comes from showing your work, not just your total. A client who sees a clear list of tasks, hours, and dates rarely argues about the bill. A client who sees one lump sum often does.

Your time tracking data is proof. When you present it well, you stop defending invoices and start having calm, factual conversations.

What templates help present time tracking data to clients?

Start with a simple summary report. One page. Client name, billing period, and total hours split into billable and non-billable. Add a short line for each project and task.

Then attach a detail report behind it. This lists every time entry: date, person, task, hours, and a one-line note. Most time tracking tools generate detailed reports in a few clicks, so you are not building this by hand.

A third template helps for retainers. Show hours used, hours remaining, and any rollover. This answers the “how much is left?” question before it gets asked.

Keep the language plain. “Strategy call, 1.5 hours” beats “Consulting services rendered.” Clients trust notes they can read.

Match the format to the reader. Finance teams want totals and rates. Project managers want hours by project and task. Send each group what they need.

How often should you send time tracking reports to clients?

Send a report with every invoice, at minimum. That is the baseline. It ties the bill to the work.

For active projects, send a weekly or biweekly summary. Short and simple. It keeps surprises out of the final invoice.

For retainers, send a monthly statement. Show hours used and hours left. This prevents the awkward “we went over” talk at the end of the quarter.

For long projects, add a mid-project check-in. Share hours to date against the budget. Clients appreciate the heads-up, and you catch scope creep early.

The rule: the bigger the bill, the more often you share. Frequency builds trust faster than any single perfect report.

How do you handle client pushback on billable hours?

Do not get defensive. Get specific. Pull up the detail report and walk through the entries together.

Most pushback comes from three things: unclear notes, surprise totals, or work the client did not expect. Each has a fix.

Unclear notes? Rewrite your entry descriptions going forward. “Reviewed draft” becomes “Reviewed 40-page draft and left 12 comments.”

Surprise totals? Send reports more often. A client who saw the hours climb week by week will not flinch at the invoice.

Unexpected work? Point to the email or meeting where it was approved. This is why you log change orders as they happen.

If a client still disputes a specific entry, offer to adjust it. One small write-off can save the relationship. Then fix the root cause so it does not repeat.

Stay calm, stay factual, and let the data do the talking. A clean report turns a fight about money into a review of the work itself.

What are the risks of AI-based automatic time tracking for consultants handling confidential client work?

AI-based automatic time tracking can see more than you think. Tools that watch your keyboard and mouse, or log which apps and websites you use, may capture client names, file titles, and document contents. For consultants under NDA, that data collection is a real risk. It can breach a contract, expose confidential work, and put a client relationship on the line.

The tool itself is not the problem. The problem is what it records, where that data goes, and who agreed to it. Below are the four risks to manage before you switch on automatic tracking.

Do client NDAs permit AI-based activity monitoring?

Most NDAs do not mention activity monitoring at all. They were written to cover what you do with client information, not how your software watches you work. That silence cuts both ways. A strict confidentiality clause may treat any third-party access to client data as a breach, even if the data never leaves your laptop.

Read the confidentiality and data-handling sections of each contract before you enable automatic tracking. Look for words like “subcontractors,” “third parties,” and “data processing.” If the NDA requires written approval before sharing client information with anyone, an AI tool that uploads activity data to its own servers counts as sharing.

When in doubt, ask the client. A short email beats a breach claim. Many clients will say yes once you explain that you only track time, not content.

How should you disclose AI tracking to clients?

Disclose it in writing, before the engagement starts. Add one plain sentence to your contract or statement of work: “I use [tool name] to track time on your projects. It records app and document activity to build accurate timesheets. It does not read or store your files.”

Name the tool. Say what it captures. Say where the data lives. Then say what it does not do. Vague promises like “we respect your privacy” do not help. Specific ones do.

If a client objects, offer a fallback. You can exclude their projects from automatic tracking and use manual time tracking instead. Most clients care about confidentiality, not about how you count hours. Giving them a choice removes the friction.

What happens when AI misattributes billable time to the wrong client?

AI guesses. It sorts your activity into projects based on patterns, and it gets them wrong. A quick check of a client email during another client’s call can log that minute to the wrong file. Over a month, small errors add up.

The damage is not just a wrong number. If you bill Client A for time spent on Client B, you have shared nothing, but you have billed inaccurately. That can trigger a credit note, a difficult conversation, or a lost client.

The fix is a review step. Treat AI suggestions as drafts, not final entries. Spend five minutes each evening confirming that time entries sit under the right client and project. This keeps your billable time management honest and your invoices defensible.

How do you ensure consent, data residency, and audit trails with AI time tracking?

Three controls cover most of the risk.

Consent. Get it from every party. Your own team should know what is tracked and why. Your clients should approve it in writing. Keep a record of both.

Data residency. Check where the vendor stores data. Some consultants must keep client data inside the EU, the UK, or the US. A tool that routes everything through one region may not fit. Ask the vendor for their data center locations and their GDPR or SOC 2 status before you sign.

Audit trails. You need a record of who changed what, and when. If a client questions an entry, you should be able to show the original AI suggestion, your edit, and the timestamp. Most time tracking tools keep this history. Confirm it before you rely on it.

One more control: turn off content capture. Many automatic time tracking apps let you record app and window titles only, with no screenshots and no file contents. That setting alone removes most of the confidentiality risk while keeping accurate time tracking intact.

None of this makes AI tracking unusable. It makes it safe. Consultants who need automatic tracking can have it, as long as consent, residency, and audit trails are handled up front.

Frequently Asked Questions

What is the best time tracking software for consultants?

Harvest is the best overall pick for most consultants because it tracks billable hours and turns them into invoices in one tool. Toggl Track is the runner-up for automatic time tracking. Clockify is the best free option for solo consultants. Deltek Vantagepoint fits large or global firms.

How do consultants track their time?

Most consultants track time three ways: a start/stop timer, manual time entries, or automatic time tracking that logs activity in the background. The method matters less than the habit. Log time the same day, tag each entry by client and project, and mark it billable or non-billable. That keeps records clean enough to invoice without guesswork.

Is Clockify actually free?

Yes. Clockify’s free plan has no time limit and no cap on users. You get unlimited tracking, projects, and basic reports at no cost. The catch is that advanced features — invoicing, budgeting, and deeper reporting — sit behind paid plans that start around $3.99 per user per month. For a solo consultant, the free tier often covers everything.

What is the best software for time tracking?

It depends on what you need it to do. For simple tracking plus invoicing, Harvest wins. For automatic tracking and integrations, Toggl Track leads. For a free start, Clockify. For enterprise consulting and professional services teams, Deltek Vantagepoint. There is no single best tool — only the best fit for your billing model and team size.

Is there a free app to track consulting hours?

Yes. Clockify and Toggl Track both offer free plans that handle consulting time tracking well. Both have iOS and Android apps, so you can track time from your phone or desktop. Harvest offers a free trial but not a permanent free plan. If budget is the deciding factor, start with Clockify and upgrade only when you need invoicing.

How to bill time as a consultant?

Track every billable hour by client and project, then convert those entries into an invoice. Most tools let you pull unbilled time into a draft invoice, apply your rate, and send it. Decide your rate structure first — hourly, retainer, or fixed-fee — because it changes how you set up projects. Rounding rules and expense pass-throughs should be set before your first invoice, not after.

What is the best free time tracking app for consultants?

Clockify is the best free app for most consultants. It offers unlimited users and projects on the free plan, works on desktop and mobile, and includes a timer plus manual entry. Toggl Track’s free plan is a close second, with a cleaner interface and solid reporting. Both let you track billable versus non-billable time at no cost.

How do consultants track billable hours accurately?

Use a timer instead of reconstructing your day from memory. Start it when you begin client work and stop when you pause. Tag the entry to the right client and project immediately. Review your week every Friday to catch gaps. Automatic time tracking helps here — it captures activity you would otherwise forget, so fewer billable minutes slip through.

Can time tracking software generate detailed reports for clients?

Yes. Most tools can generate detailed reports that show hours by project, task, and team member. You can filter by date range and export to PDF or CSV. Harvest and Toggl Track both produce client-ready reports. Some tools also offer a shared dashboard so clients can see progress without asking. Check the report format before you commit — a clean report saves you time at invoicing.

How do consultants handle time tracking for multiple clients and projects?

Set up a separate project for each client, then use tasks or tags to split work within it. Color-code projects so your timer list stays readable. Use a tool that supports project and task hierarchies — Clockify, Harvest, and Toggl Track all do. Review a per-client summary weekly so no project drifts. When you juggle many clients, automatic tracking and keyboard shortcuts make it easy to switch without losing time.
