Best Construction Invoicing Software for Contractors (2026) | Projul

Construction invoicing software helps contractors create, send, and track invoices tied to their actual job costs, change orders, and project milestones. If you’re still sending invoices from a spreadsheet or a generic accounting tool, you’re leaving money on the table and wasting hours every week.

We ranked 8 of the best construction invoicing software platforms for 2026 based on real pricing, construction-specific features, QuickBooks integration, and how well they actually work on a jobsite. Projul takes the #1 spot because it handles invoicing alongside every other part of your business, all without charging you per user.

What Makes Construction Invoicing Different from Regular Invoicing?

Most invoicing software was built for freelancers or retail businesses. Send an invoice, get paid, done. Construction doesn’t work that way.

Your invoicing needs to handle:

• Progress billing so you can bill based on percentage of completion, not just flat amounts
• Retention tracking to hold back the agreed percentage and release it at closeout
• Change orders that automatically update the contract value and flow into your next invoice
• Lien waivers that get sent and signed alongside payment
• AIA-style billing (G702/G703 forms) for commercial work
• Job costing integration so every invoice ties back to actual costs and you can see real profit margins

If your invoicing tool can’t do at least half of those things, it wasn’t built for construction. Period.

The 8 Best Construction Invoicing Software Platforms (2026)

1. Projul - Best All-in-One for Contractors

Pricing: Core at $4,788/year, Core+ at $7,188/year, Pro at $14,388/year (annual pricing, no per-user fees included)

Projul was built by a contractor who got tired of duct-taping five different tools together. Invoicing is just one piece of a platform that covers CRM, estimating, scheduling, time tracking, job costing, and project management.

What makes Projul’s invoicing stand out:

• Progress billing built directly into each project. Bill by percentage complete, line item, or milestone.
• Change orders flow straight into invoices. When the homeowner adds that extra bathroom vanity, it shows up on the next bill automatically.
• Retention tracking with automatic calculations and release scheduling
• QuickBooks Online two-way sync so your books stay current without double entry
• Online payments through JustiFi with next-day deposits. Your clients pay from the invoice link on their phone.
• Customer portal where clients can see their invoices, approve change orders, and make selections. No more “did you get my invoice?” phone calls.

The biggest thing contractors love about Projul’s pricing is what’s NOT on the invoice: per-user fees. Most construction software charges $50-$100 per user per month. When you’ve got 15 office staff, 30 field crew, and 20 subs who need access, that adds up to thousands. Projul’s flat rate means everyone who needs access gets it.

G2 Rating: 4.7/5 | Capterra Rating: 4.7/5

Best for: Contractors who want one platform for everything and are tired of paying per user.

2. QuickBooks Online - Best Standalone Accounting with Invoicing

Pricing: Simple Start at $38/mo, Essentials at $65/mo, Plus at $99/mo, Advanced at $275/mo

QuickBooks is the accounting software most contractors already use, and its invoicing is solid for basic billing. You can create professional invoices, accept online payments, set up recurring billing, and track what’s outstanding.

But here’s the thing. QuickBooks was built for accounting, not construction. It doesn’t understand progress billing, retention, or change orders out of the box. You’ll need workarounds, custom fields, or third-party apps to make it work for construction-specific invoicing.

That said, QuickBooks integration is basically non-negotiable for any construction invoicing tool you pick. Your accountant expects it. Your bookkeeper expects it. Your tax preparer expects it. If your invoicing software doesn’t sync with QuickBooks, you’re creating more work, not less.

G2 Rating: 4.0/5 | Capterra Rating: 4.3/5

Best for: Solo contractors or very small operations that just need basic invoicing with solid accounting.

3. Buildertrend - Best for Large Residential Builders

Pricing: Starts around $499/mo (custom pricing, contact for quote). Per-user fees apply on most plans.

Buildertrend is a well-known name in residential construction software. Their invoicing ties into their project management, and they support progress billing and change order tracking. The customer portal lets homeowners view and pay invoices online.

Contractors across the country trust Projul to run their businesses. Read their reviews.

The downside? Cost. Buildertrend’s pricing has gone up significantly in recent years, with many users reporting annual bills north of $8,000-$10,000. And that per-user pricing adds up fast when your team grows. Several G2 reviewers mention sticker shock after the first year.

Buildertrend integrates with QuickBooks and Xero for accounting sync.

G2 Rating: 4.2/5 | Capterra Rating: 4.5/5

Best for: Larger residential builders and remodelers who can absorb the higher price tag.

4. JobTread - Best for Estimating-to-Invoice Workflow

Pricing: Starts around $4,788/year (custom pricing, contact for quote)

JobTread has gotten a lot of attention for its estimating and budgeting tools. The invoicing flows directly from your estimates and budgets, which is great for keeping your numbers connected. You build the estimate, win the job, and invoice from the same data without re-entering anything.

JobTread supports progress billing, change orders, and integrates with QuickBooks Online. The interface is clean and the reporting is strong.

The trade-off is that JobTread focuses heavily on the financial side. If you need full project management, scheduling, CRM, and field tools in the same platform, you’ll still be adding other software to fill the gaps.

G2 Rating: 4.8/5 | Capterra Rating: 4.8/5

Best for: Contractors who are very budget and estimate-focused and want tight financial tracking.

5. FreshBooks - Best Generic Invoicing for Sole Proprietors

Pricing: Lite at $21/mo (5 clients), Plus at $38/mo (50 clients), Premium at $65/mo (500 clients)

FreshBooks makes invoicing dead simple. Create an invoice in 30 seconds, send it, get paid. The interface is one of the cleanest in the business and the mobile app works great.

But FreshBooks was not built for construction. There’s no progress billing, no retention tracking, no change order integration, and no job costing. You’re getting a really good generic invoicing tool, not a construction invoicing tool.

If you’re a one-person handyman or small specialty contractor who invoices flat-rate jobs, FreshBooks could work. The moment you need to bill a project in phases or track retention, you’ve outgrown it.

G2 Rating: 4.5/5 | Capterra Rating: 4.5/5

Best for: Sole proprietors and handymen with simple, flat-rate billing needs.

6. Xero - Best for Contractors with International Operations

Pricing: Starter at $20/mo, Standard at $47/mo, Premium at $80/mo

Xero is a cloud accounting platform from New Zealand that’s popular in the US, UK, and Australia. Its invoicing is clean, supports online payments, and handles multi-currency if you do work across borders.

Like QuickBooks, Xero is an accounting tool first. It doesn’t understand construction workflows natively. No progress billing, no retention, no AIA forms. But it does integrate with several construction-specific platforms (including Projul) that handle the construction side while Xero handles the books.

G2 Rating: 4.3/5 | Capterra Rating: 4.3/5

Best for: Contractors who prefer Xero over QuickBooks or operate internationally.

7. Invoice Ninja - Best Free/Budget Option

Pricing: Free (open source, self-hosted), Pro at $10/mo (hosted)

Invoice Ninja is an open-source invoicing tool that’s free if you host it yourself, or $10/mo for the hosted version. It handles basic invoicing, recurring invoices, expense tracking, and online payments. For $10 a month, the feature set is impressive.

The catch? Zero construction-specific features. No progress billing, no change orders, no job costing, no retention. It’s a generic invoicing tool at a price that’s hard to beat. If you just need to send simple invoices and get paid, Invoice Ninja is a scrappy option for very small operations.

G2 Rating: 4.7/5 | Capterra Rating: 4.8/5

Best for: Very small contractors or startups on an extremely tight budget who just need basic invoices.

8. Contractor Foreman - Best Budget Construction-Specific Option

Pricing: Free plan (1 user), Standard at $49/mo, Plus at $87/mo, Premium at $148/mo

Contractor Foreman is the budget pick on this list for construction-specific software. It includes invoicing, estimating, scheduling, and project management at a lower price point than most competitors. They even have a free plan for one user.

Invoicing features include progress billing, change order tracking, and QuickBooks integration. The interface is more basic than some competitors, and some users report the mobile experience could be smoother. But for a contractor watching every dollar, it’s a solid starting point.

G2 Rating: 4.5/5 | Capterra Rating: 4.5/5

Best for: Budget-conscious contractors who need construction-specific features without the premium price tag.

Why QuickBooks Integration is Non-Negotiable

Here’s a conversation that happens in every construction company in America:

Your bookkeeper asks, “Can you export the invoices into QuickBooks?” And if the answer is no, or if it requires manual re-entry, you’re burning hours every month and introducing errors.

Around 80% of small contractors use QuickBooks for their accounting. Your invoicing software needs to play nice with it. Look for two-way sync, not just a one-way export. Two-way means when a payment is recorded in QuickBooks, it updates in your invoicing tool too. And when you create an invoice in your construction software, it shows up in QuickBooks automatically.

Projul’s QuickBooks Online integration syncs customers, invoices, payments, and expenses in both directions. You create the invoice in Projul where all your project data lives, and it lands in QuickBooks where your bookkeeper lives. Everyone’s happy.

What to Look for When Choosing Construction Invoicing Software

Not every contractor needs the same thing. But here’s what you should be evaluating:

1. Does it understand construction billing? Progress billing, retention, and change orders are the basics. If the software can’t handle these, it wasn’t built for you.

2. Does it connect to your accounting software? QuickBooks or Xero integration is a must. Double data entry is a profit killer.

3. Can your clients pay online? In 2026, mailing checks should be optional, not required. Online payment options get you paid faster. Some contractors see a 30-40% improvement in days-to-payment after adding online invoicing.

4. Does it tie into the rest of your workflow? The best invoicing happens when it’s connected to your estimates, change orders, and job costs. Standalone invoicing tools create data silos that cost you time and visibility.

5. What’s the real cost? Per-user pricing looks cheap until you add your whole team. Calculate the total annual cost with every user who needs access, not just the base price.

6. Does it work on a phone? Your PM is on a jobsite, not sitting at a desk. If they can’t send or check an invoice from their truck, the tool is only half-useful.

7. How fast do you get paid? Look at payment processing fees and deposit timing. Some platforms offer next-day deposits. Others hold your money for a week. That cash flow difference matters when you’ve got payroll on Friday.

How Projul Handles the Full Invoice Lifecycle

Most invoicing tools handle the “send invoice, get paid” part. Projul handles the whole story:

Lead comes in through the CRM. You build an estimate. The client signs it in the customer portal. It becomes a project with a budget. Your crews get scheduled and their time gets tracked against the budget.

When it’s time to bill, you create an invoice from the actual project data. Every cost, every change order, every material is already there. The retention calculates automatically. The client gets an email with a link to view and pay in the customer portal. The payment syncs to QuickBooks.

That’s one flow. No copying numbers between apps. No “let me check the spreadsheet.” No waiting for the office manager to get back from lunch to process an invoice.

Your field team tracks time and your office team sees the costs update in real time. When you invoice, you’re billing from real numbers, not estimates from three weeks ago.

Frequently Asked Questions

What is construction invoicing software? Construction invoicing software is a tool that helps contractors create and send invoices specific to construction projects, including features like progress billing, retention tracking, change order integration, and job cost tie-ins that generic invoicing tools don’t offer.

What’s the best free construction invoicing software? Contractor Foreman offers a free plan for one user that includes basic construction invoicing features. Invoice Ninja is free and open-source but lacks construction-specific features like progress billing and retention. For most contractors, free tools have limits that cost more in wasted time than a paid tool would cost in subscription fees.

Does QuickBooks work for construction invoicing? QuickBooks handles basic invoicing well and is great for accounting, but it doesn’t natively support progress billing, retention tracking, or change orders. Most contractors use QuickBooks for accounting and pair it with a construction-specific platform like Projul that syncs invoices back to QuickBooks automatically.

How much does construction invoicing software cost? Pricing ranges widely. Generic tools like FreshBooks start at $21/mo. Construction-specific platforms range from free (Contractor Foreman, limited) to $4,788 to $14,388/year for full-featured options like Projul. Buildertrend starts around $499/mo with per-user fees on top. Always calculate total cost including every user who needs access.

What is progress billing in construction? Progress billing is a method where contractors invoice clients based on the percentage of work completed rather than a single lump sum. For example, if a $100,000 project is 40% done, you’d invoice $40,000. This keeps cash flowing throughout the project instead of waiting until the end.

What are lien waivers and why do they matter for invoicing? A lien waiver is a document signed by a contractor or subcontractor that gives up the right to place a lien on a property for the amount being paid. Many states require lien waivers with each payment. Having them built into your invoicing workflow saves time and keeps you legally compliant.

Can I use regular invoicing software for construction? You can, but you’ll hit walls fast. Regular invoicing tools like FreshBooks or Invoice Ninja don’t support progress billing, retention, change orders, or AIA billing formats. For simple flat-rate jobs, they might work. For anything involving phased billing or multiple draw schedules, you need construction-specific software.

What’s the fastest way to get paid as a contractor? Use invoicing software with built-in online payments. Contractors who switch from mailed paper invoices to online invoicing typically see payment times drop by 10-15 days. Tools like Projul offer next-day deposits through integrated payment processing, so the money hits your account faster too.

The Bottom Line

The right construction invoicing software saves you hours every week and gets you paid faster. If you’re just sending simple invoices, a basic tool like FreshBooks or Invoice Ninja will get the job done. But if you’re running real construction projects with progress billing, retention, change orders, and a team that needs access, you need a platform built for how contractors actually work.

Projul gives you invoicing that’s connected to your estimates, schedules, job costs, and QuickBooks, all in one platform with no per-user fees. Start a free trial and see how it works on your next project.
