Start with time tracking that captures which job site each employee works on every day. Time tracking apps like Busybusy, ClockShark, or even simple spreadsheets work as long as employees record their hours by project. The key is assigning hours to a specific job when they happen, not trying to reconstruct it later.

Paper timesheets still work if your crew fills them out daily and notes the job site on each entry. The problem with paper is getting that information into your accounting system takes extra steps. Digital time tracking that syncs with QuickBooks or your payroll provider eliminates manual data entry and reduces errors.

Set up your accounting software to track labor by job. In QuickBooks, this means enabling job costing and creating a customer or project for each job site. When you run payroll, allocate hours to the correct jobs so labor costs flow to the right place. Without this setup, all your labor shows as one lump sum and you have no idea which jobs are profitable.

For construction contractors running multiple crews across different sites, GPS-based time tracking adds accountability. Employees clock in when they arrive and the system logs their location. This prevents time theft and gives you accurate data without relying on memory or estimates.

Calculate your true labor cost per hour, not just wages. Include payroll taxes, workers comp insurance, and any benefits you provide. If you pay an employee $20 per hour but your actual cost is $26 after taxes and insurance, use that $26 figure when tracking job costs. Otherwise your profitability numbers are wrong.

Review labor allocations weekly before finalizing payroll. Catch mistakes while everyone still remembers what happened. An employee who worked three different job sites in a week might forget to log one correctly. Weekly review gives you a chance to fix it before it hits your books.

The payoff for tracking labor by job is knowing which projects actually made money. You might think a job was profitable based on the contract price, but when you see the actual labor hours it consumed, the picture changes. That information helps you bid future work more accurately and identify which types of jobs are worth pursuing.

If setting up job costing feels overwhelming, a bookkeeper near Fayetteville familiar with job-based businesses can configure your system correctly from the start. Getting the structure right upfront saves hours of cleanup later and gives you data you can actually use to run your business.
