How to See True Profit on Every Project
(And How to Fix It in QBO)
Winning a $1 million contract feels like a massive victory. But if your bank account is shrinking even while sales are booming, you’re not alone. In construction, excavation, and project-based industries, high revenue does not always mean high profits.
The secret to knowing where your money is actually going? Job costing.
If you are doing government contracting or multi-stage projects, tracking revenue and expenses for every single job isn’t optional—it’s vital. Here is why job costing matters and how to manage it in QuickBooks Online (QBO) without going crazy.
Key notes
- Identify Losing Jobs: Uncover hidden losses obscured by overall company Profit & Loss statements.
- Factor in Full Labor Costs: Account for gross wages and employer taxes per project to prevent profit drain.
- Include Equipment & Overheads: Track machine costs and wear to bid accurately on future contracts.
- Proactive QBO Setup: Assign project tags continuously to avoid a end-of-month cleanup of hundreds of transactions.
A profitable company P&L can hide losing projects
Your overall Profit & Loss statement might show a positive net profit at the end of the month, giving you a false sense of security. But when you zoom into individual projects, you often discover that two great jobs are silently subsidizing three losing ones. Aiming for a gross profit margin of 15% to 20% is a healthy baseline in construction—if a job falls below that, you need to know immediately so you can adjust your next bid.
Labor taxes and machine costs will surprise you
The biggest profit drainers are the hidden costs people forget to tag to a project. It’s easy to assign raw materials, but are you assigning gross employee wages and the employer payroll taxes for the hours spent on that specific site? What about heavy machinery wear, fuel, and maintenance? When you leave out labor overhead and equipment costs, a job that looked profitable on paper can easily turn into a net loss.
Don’t wait until the end of the month to tag transactions
QBO’s Projects feature handles job costing beautifully, but only if you feed it clean data. A major trap business owners fall into is ignoring project tagging during the month, leaving 500+ unassigned transactions to sort through at month-end. That delay means you’re looking at old data instead of catching budget overruns in real time.
At the end of the day, accurate job costing gives you total clarity. It tells you exactly which jobs are making you money, which ones are draining your cash flow, and how to bid smarter for long-term success.
