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, location for division if multi-division.
Create a class for each active job — retire 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, Equipment Costs.

Direct labor is only part of true cost. Burden rate captures: payroll tax, benefits, training, idle time, vehicle costs, small tools, 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; lose money at scale.

Job Profitability Report: per active job, show revenue earned, costs incurred, gross profit, % complete.
WIP Schedule: list of all open jobs with contract value, costs incurred, % complete, costs to complete, billings to date, 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.
