Job Costing for Small Contractors Without Enterprise Software

How to set up real job-level profitability tracking in QuickBooks or Xero, without buying construction-specific software you don't need.

Without job costing, you know overall profit, but not which jobs were profitable, which lost money, or why.
Construction and trade contractors live and die by per-job margin. Some jobs always lose; you need to know which.
Bonding companies, lenders, and serious buyers require WIP schedules and job-level data.
Best practice: every direct cost (labor, materials, subs, equipment) tagged to a specific job.

Enable 'Track classes' and 'Track locations': use class for job and location for division if multi-division.
Create a class for each active job; retire it when closed.
Use 'Projects' feature (QBO Advanced) for richer job profitability reporting.
Customer/project structure: customer = client/owner, project = specific job for that customer.
Set up a 'Job Cost' account structure: separate Direct Labor, Direct Materials, Subcontractors, and Equipment Costs.

Direct labor is only part of true cost. Burden rate captures: payroll tax, benefits, training, idle time, vehicle costs, small tools, and insurance.
Typical burden rate: 15–35% of direct labor cost on top of wages.
Calculate once per year, apply consistently. Refresh annually.
Without burden allocation: jobs look more profitable than they are, you undercut on bids, and you lose money at scale.

Job Profitability Report: per active job, show revenue earned, costs incurred, gross profit, and % complete.
WIP Schedule: list of all open jobs with contract value, costs incurred, % complete, costs to complete, billings to date, and over/under billings.
Backlog Report: signed contracts not yet started; shows future revenue.
Closed Jobs Report: completed jobs with final margin, for benchmarking future bids.
