The Job Profitability Summary is your starting point. This report lists all your jobs with total income, total costs, and gross profit for each one. You can see at a glance which projects made money and which ones lost money. Run this monthly to track how active jobs are trending and to review completed jobs before moving on to the next project.

Job Profitability Detail goes deeper. When a job shows lower profit than expected on the summary, you pull the detail report to see exactly where the money went. Every expense coded to that job appears line by line. You’ll see if materials ran over, if labor hours exceeded the estimate, or if a change order never got billed. This is the report that tells you why a job underperformed.

Profit and Loss by Job is another way to view the same data, formatted like a traditional income statement but filtered or grouped by project. Some people find this layout easier to read because it follows the standard P&L structure they’re used to seeing.

If you’re tracking budgets, a Job Cost vs. Budget report compares what you estimated to what you actually spent. This is where you catch problems while there’s still time to adjust. A job that’s 60% complete but has already burned through 80% of the materials budget needs attention now, not when the final invoice goes out.

These reports only work if your construction job costing is set up correctly. Every expense needs to hit the right job. Every labor hour needs to be assigned to the correct project. Every subcontractor invoice needs to be coded properly. Run a profitability report on a job where half the costs landed in general overhead and the numbers are meaningless.

In QuickBooks, these reports live under the Reports menu. QuickBooks Online calls them Project Profitability reports if you’re using the Projects feature. QuickBooks Desktop has Job reports under the Jobs, Time & Mileage category. The names vary slightly by software version but the concept is the same.

The goal is knowing your real margins by project so you can estimate better, catch problems earlier, and stop taking jobs that lose money. A real estate bookkeeper in American Fork or construction accountant who understands job costing can help you configure these reports and make sure the underlying data is accurate enough to trust.
