If you're a contractor or construction company owner, you already know the drill—multiple jobs, scattered crews, last-minute change orders… and then comes the paperwork.
Invoicing is often the last thing on your list, but it directly affects your cash flow. And let’s be honest: missed invoices, late payments, and underbilling are all too common in this industry.
That’s why the right invoicing software isn’t a luxury—it’s a must-have. In this guide, we’ll share the list of best invoicing software tools for contractors and how to choose one that fits the way you work.
Picture this: You just wrapped up a remodel, and instead of sending out the invoice that same day, it gets pushed to the weekend. Then, you forget. Two weeks later, you’re chasing payment and wondering why your cash flow is tight.
Sound familiar?
Construction work isn’t like selling products—you deal with progress billing, change orders, retainage, and complex timelines. Generic invoicing tools just don’t cut it.

Pros:
Cons:
Choosing the right construction invoice software comes down to more than just price. Here are the key things to consider:
Can it handle things like progress billing, retainage, change orders, and deposits?
If you use QuickBooks (like most contractors do), your invoicing software should sync seamlessly.
You need something that works fast, especially on job sites. A clunky tool that requires a manual won’t get used.
Look for tools that work just as well on your phone or tablet as they do on a computer.
Will it grow with you? If you’re adding more crews or managing multiple jobs, your invoicing tool should keep up.
If something goes wrong or you need help setting it up, can you get real support—or are you stuck with bots and forums?
If you're still sending out invoices in Word, Excel, or (gulp) handwritten notes, it’s time for an upgrade.
Ontraq makes invoicing part of your entire financial picture—not just a task you remember at the end of the week. With real-time job costing, expert-reviewed financials, and project-level accuracy, you’ll know exactly what to bill, when to bill, and how to stay profitable.

Let’s be real—getting paid shouldn’t be a hassle. But if you’re still messing with spreadsheets or chasing down clients for checks, it probably is.
The right invoicing tool doesn’t just help you send bills—it gives you a clearer picture of where your money’s going (and coming from), helps you stay on top of cash flow, and frankly, saves you from a whole lotta stress.
We’ve seen it happen: contractors switch to smarter invoicing software and suddenly... they’re getting paid faster, spending way less time on admin, and actually seeing where their jobs stand financially. No more guesswork. No more “wait, did I invoice that job?” moments.
And Ontraq? It’s not just another invoicing app. It’s like a financial sidekick—built just for contractors. Invoicing, job costing, QuickBooks sync, all in one place.

Honestly? It’s not that complicated. A proper invoice should include your project name, a list of what you did (labor, materials, etc.), how much it costs, when it’s due, and if there’s any holdback. With Ontraq, you just plug in the basics and it builds the invoice for you. Way better than copy-pasting from an old Word doc.
Yep, most invoicing tools offer templates that make the process easier and invocies look professional. You just drop in your info—logo, job details, pricing; and it looks clean and professional. It’s fairly easy even for first timers.
The good ones do. Ontraq, JobTread, Knowify—these all play nice with QuickBooks, Xero, and a few others. That means less double entry, fewer errors, and no more digging through emails to find that one receipt you forgot to log.
Glad you asked. If you’re in the trades, look for software that can handle:
Zoho Invoice is a decent free solution. However, it lacks construction-specific features. For serious contractors, a paid tool like Ontraq offers more long-term value (plus they have a great free trial)
Absolutely. Even solo contractors benefit from it. Because it saves time, reduces errors, and improves cash flow. Over time, the ROI far outweighs the cost.
