QuickBooks Online has a Projects feature that lets you assign income and expenses to individual jobs. You can track what you’ve billed a customer, what you’ve spent on that project, and see the profit margin. For many project-based businesses like consultants, creative agencies, or professional services firms, this is enough to get a clear picture of job-level profitability.

Where it gets more complicated is when you need detailed cost breakdowns within a job. A general contractor tracking labor, materials, and subcontractor costs across multiple phases needs more structure than what QBO gives you out of the box. You won’t find built-in cost codes or phase tracking the way construction-specific software handles it. But that doesn’t mean QBO can’t do it. With the right chart of accounts, item categories, and consistent coding discipline, you can build a construction job costing structure that gives you meaningful project-level reporting.

The biggest gap most business owners run into isn’t the software itself. It’s the setup. A default QBO configuration treats every business the same. There’s no distinction between a landscaper tracking costs on ten active jobs and a retail shop selling products. If you just turn on Projects and start entering transactions without building the right structure underneath, the reports won’t tell you anything useful.

A few specific limitations worth knowing about. QBO doesn’t handle retainage natively, so you’ll need workarounds if that’s part of your contracts. Progress billing requires some manual setup. And committed costs (contracts you’ve signed but haven’t been invoiced for yet) won’t show up automatically, meaning your job cost reports can look better than reality until those invoices arrive.

For skilled trades and smaller contractors running a handful of jobs at a time, QBO configured correctly is often the most practical solution. You get cloud access, your bookkeeper and tax accountant can work in the same file, and the cost is reasonable. Jumping to construction-specific software makes more sense when you’re running dozens of active projects or need integrated scheduling and project management alongside your accounting.

The answer really comes down to setup and consistency. QBO can handle job costing for most small businesses if someone who understands both the software and your industry builds the structure properly. As a small business accounting firm working with project-based businesses across the East Valley, we see the difference between a well-configured QBO file and one that was thrown together. The software is the same. The results are completely different.
