What Is the Best Invoicing Software for Construction?
Top Pick: Buildxact — Best for Residential Builders Needing Progress Billing and Estimate-to-Invoice Conversion
Buildxact is the best invoicing software for construction overall. It turns your estimate straight into a progress invoice. It also syncs with QuickBooks. That combo means less manual data entry. It also means you get paid faster.
Runner-Up: ServiceTitan — Best for Commercial Contractors Managing AIA-Style Progress Billing and Retainage
ServiceTitan is the runner-up. It suits commercial contractors. They need AIA-style progress billing and retainage tracked in one place.
Most general accounting tools were not built for the way contractors bill. They miss retainage, phased draws, and change orders. That is why the best invoicing software for construction is usually progress billing software with job costing baked in.
Here is how the top two compare on the features that matter most to contractors:
| Feature | Buildxact | ServiceTitan |
|---|---|---|
| Progress billing | Yes | Yes (AIA-style) |
| Retainage tracking | Yes | Yes |
| Job costing | Yes | Yes |
| Accounting sync | QuickBooks, Xero | QuickBooks, Sage |
| Best for | Residential builders | Commercial contractors |
Both options help you send professional invoices. They help you track payments. They help you keep a healthy cash flow. The right pick comes down to your project type.
Buildxact is the best invoicing software for construction overall, especially for residential builders who need progress billing and estimate-to-invoice conversion. ServiceTitan is the runner-up for commercial contractors managing AIA-style progress billing and retainage. Both tools include job costing and sync with major accounting platforms, so the right pick depends on your project type.
What Features Should Construction Invoicing Software Have?
The most important feature is progress billing. This means you can invoice in phases as work gets done, not just once at the end. Without it, you are guessing at payments and waiting too long to get paid.
Progress Billing and Milestone Invoicing
Progress billing software lets you bill by percentage of completion or by project milestone. Each invoice pulls from your estimate. This means you skip manual data entry and avoid mistakes. This is how contractors get paid faster on long jobs.
Retainage and Change Order Management
Retainage tracking keeps the percentage a client holds back visible on every invoice. This way nothing gets forgotten at closeout. Change order management ties approved changes to the right invoice. This way extra work never goes unbilled.
Job Costing and Expense Tracking
Job costing shows labor, materials, and expenses per project. This way you know which jobs make money. Look for accounting integrations with QuickBooks or Xero, mobile invoicing from the job site, and automated payment reminders. Online payment options like credit card, ACH, and PayPal or Stripe help you get paid on time.
7 Best Invoicing Software for Construction
Buildxact is the best contractor invoicing software for residential builders because it turns an approved estimate into a progress invoice in a few clicks. ServiceTitan is the runner-up and fits commercial contractors best, thanks to AIA-style progress billing and retainage tracking built in.
Below are seven tools worth a look, each matched to a contractor type.
Buildxact — Best for Residential Builders
Buildxact is construction invoicing software made for home builders and remodelers. You build the estimate first, then convert it straight into an invoice. No re-typing numbers.
Progress billing and retainage are built in, so phased jobs stay accurate from deposit to final draw. QuickBooks and Xero integrations keep your books in sync.
Pricing starts around $149 per month, billed annually. It suits residential builders who want estimates and invoices in one place.
ServiceTitan — Best for Commercial Contractors
ServiceTitan is built for contractors running bigger commercial jobs. It handles AIA-style progress billing, retainage, and change orders without workarounds.
Field service management tools let crews update job status from the site. That data flows into the invoice, so billing matches the work installed.
It also covers customer relationship management and reporting and analytics. Pricing is custom-quoted and runs high — often $300+ per user monthly. It fits commercial contractors with steady job volume.
Knowify — Best for Job Costing and Progress Billing
Knowify pairs job costing with progress billing in one platform. Every invoice ties back to real labor and material costs, so you see profit per job as you bill.
It supports AIA-style billing, retainage, and change orders. That makes it a strong fit for subcontractors on commercial projects.
Knowify connects with QuickBooks Online and QuickBooks Desktop. Plans start near $149 per month for small teams. It suits contractors who need tight job costing alongside construction billing software.
Tradify — Best for Trade Contractors
Tradify is invoicing software for contractors in the trades — plumbers, electricians, and HVAC techs. You create quotes, jobs, and invoices on your phone.
It handles invoices and estimates, tracks payments, and sends automated payment reminders. That helps small business owners get paid on time without chasing clients.
Online payment options include credit card and ACH. Tradify costs about $39 per user per month. It fits trade contractors who bill many small jobs, not phased commercial work.
Joist — Best for Small Contractors and Solo Tradespeople
Joist is a free invoicing app for contractors who want something simple. You can send professional invoices and estimates from your phone in minutes.
It works well for solo tradespeople and small crews. There is no progress billing or retainage, so it suits one-off jobs rather than long phased projects.
Joist tracks payments and lets clients pay by credit card. The free plan covers basic needs; paid upgrades add features. It is the best free invoicing app for contractors just starting out.
Xero — Best for Contractors Needing Full Accounting
Xero is full accounting software with strong invoicing. It fits contractors who want invoicing and accounting in one system instead of two.
You can set up recurring invoices, track payments, and run reporting and analytics on cash flow. Xero also supports online payment options through Stripe and PayPal.
It does not include progress billing or retainage natively. You pair it with a construction tool like Knowify for that. Plans start around $15 per month. It suits contractors who want real books, not just invoices.
QuickBooks Online — Best for General Accounting with Progress Invoicing
QuickBooks Online is the tool most construction companies already use. It supports progress invoicing, so you can bill a job in phases against one estimate.
You can send invoices and estimates, track payments, and accept credit cards and ACH. Automated payment reminders help you get paid faster.
QuickBooks pairs with most construction apps on this list, which makes it a safe hub for invoicing and accounting. Plans start near $35 per month. It fits contractors who want general accounting with progress invoicing built in.
How These Tools Compare for Construction
Most construction companies use QuickBooks Online or Xero for accounting, then add a construction-specific tool for progress billing and retainage. That combo covers both sides of billing and invoicing.
If you need estimating and invoicing together, look at Buildxact, Knowify, or ServiceTitan. If you want simple invoices and a low price, Joist or Tradify fit better.
Match the tool to your job type first. Residential builders need estimate-to-invoice conversion. Commercial contractors need AIA billing and retainage. Trade contractors need fast mobile invoices. Pick the one that matches how you bill, and the rest gets easier.
How Do You Handle Retainage and Change Orders in Invoicing Software?
Retainage and change orders are the two things that trip up construction billing. Good construction invoicing software handles both without spreadsheets. Retainage is the 5-10% a client holds back from each payment until the job is done. A change order is any added or removed work that shifts the contract price.
Automating Retainage Calculations
Manual retainage math invites errors. Modern invoicing software lets you set a retainage percentage once. Then it withholds that amount on every progress invoice automatically. It also tracks the running total held. So you know exactly what to bill back at closeout. That keeps your cash flow healthy and your invoices accurate.
Tracking and Billing Change Orders
Change orders need a paper trail before you bill them. Contractor invoicing software links each approved change order to its job. Then it adds the change order to the next invoice. This avoids disputes and manual data entry. Tools like Knowify and ServiceTitan tie change orders straight into job costing. So nothing gets missed or billed twice.
What Are the Limitations of General Accounting Software for Construction Invoicing?
General accounting software like QuickBooks and Xero was made for retail and service businesses. It was not made for contractors. It handles basic billing and invoicing fine. But it was never built for the way construction gets paid. That gap costs contractors time and money.
The biggest miss is retainage. QuickBooks Online and Xero have no built-in field for withholding 5–10% on each progress invoice. So you track it in a spreadsheet. They also can’t produce AIA pay applications. That is the standard billing format on commercial jobs. Progress billing exists in QuickBooks, but it’s clunky. It also doesn’t tie to job costing.
That broken link matters most. When invoices and job costs live in separate systems, you can’t see whether a job is actually profitable until it’s over. For small business owners juggling several projects, that’s a real risk to healthy cash flow.
How Does Invoicing Software Integrate with Project Management and Field Service Tools?
The best construction software integration links your invoicing tool right to your project management and field service management (FSM) systems. Approved change orders and completed milestones turn into invoices. No one has to retype them. That one link stops data silos and manual data entry from eating your week.
Here is how the workflow runs. A field tech marks a job complete in the FSM app. That completion flows to your project management tools. Then it flows to your invoicing software. The software pulls the right progress billing percentage and retainage holdback from the contract. No spreadsheet. No double entry.
Most top picks sync natively with QuickBooks, Xero, or Zoho Books for invoicing and accounting. Some also push updates to customer relationship management platforms. The payoff is simple: fewer errors, faster billing, and getting paid faster.
How Do You Choose the Right Invoicing Software for Your Construction Business?
The most important thing to check is progress billing and retainage support. If a tool can’t handle phased invoices and holdback, it isn’t construction invoicing software. Nice invoice templates don’t change that.
Progress Billing and Retainage Support
Match this to your role. Subcontractors need retainage tracking on every pay application. A general contractor may hold 5–10% for months. General contractors need to bill owners in phases. They also need to manage retainage across many subs at once. Ask one question: can it bill a percentage of a contract and hold back retainage automatically?
Job Costing and Reporting
Job costing software ties every invoice line to a specific project. That way you see real profit per job, not just total revenue. Look for reporting and analytics that show cost versus billed to date. Then check the rest: accounting integration, scalability, pricing, and support.
