Job Costing for Field Services Businesses

Job costing shows whether each job actually makes money after labor, materials, subcontractors, equipment, callbacks, permits, disposal, travel time, and overhead burden.

Key idea: a busy schedule can hide bad economics. Job costing tells you whether the work is profitable, not just booked.

Core job-costing metrics

Metric	What It Shows
Revenue per Job	Total customer revenue for the job.
Direct Labor Cost	Technician or crew labor assigned to the job.
Labor Burden	Payroll taxes, benefits, workers comp, and related labor costs.
Materials Cost	Parts, supplies, inventory, or project materials used.
Subcontractor Cost	Third-party labor or specialty work.
Equipment Cost	Rental, depreciation, or usage cost.
Travel / Dispatch Cost	Drive time, fuel, and inefficient routing.
Callback Cost	Rework that consumes labor and materials without new revenue.
Gross Profit	Revenue minus direct job costs.
Gross Margin %	Gross profit divided by revenue.

Simple job profitability model

Job Revenue
- Direct Labor
- Labor Burden
- Materials
- Subcontractors
- Equipment / Rental
- Permits / Disposal
- Callback / Warranty Cost
= Job Gross Profit

Job Gross Profit ÷ Job Revenue = Job Gross Margin %

Which services are profitable and which are underpriced.
Which technicians or crews produce the strongest gross profit.
Which jobs create callbacks and warranty leakage.
Which customers or contract types consume capacity without enough margin.
Whether flat-rate pricing, hourly pricing, or project pricing needs to change.
Whether the business can afford another truck, tech, or crew.
