How to Track Field Service Job Profitability
Use a simple job-level method to compare field service revenue with labor, materials, travel, and follow-up cost.
Direct answer
A field service job is profitable when the collected revenue covers the direct cost of the work and leaves enough margin for overhead. Start with the job record, not only the invoice total.
Track the direct job inputs
Use the same job record to collect the inputs for a useful estimate.
- Collected revenue, not only the invoice amount.
- Labor time and labor cost.
- Materials and parts.
- Travel or subcontractor cost when material.
- Refunds, discounts, and rework.
Use a simple calculation
Start with a consistent formula. Gross job margin equals collected revenue minus direct job cost. Gross margin percentage equals gross job margin divided by collected revenue.
Steps
- Close the job record with the final scope.
- Add labor, material, and other direct cost.
- Record collected revenue and adjustments.
- Compare the result with the quote or service agreement.
- Use the difference to improve the next estimate.
Read the result with care
One job can be unusual. Review groups of similar jobs. A low result can come from underpricing, extra travel, rework, missing materials, or a delayed payment.
FAQ
What costs should a field service business include in job profit?
Start with direct labor, materials, parts, travel, subcontractors, refunds, discounts, and rework. Add overhead later for a fuller business view.
Should job profit use invoice value or collected revenue?
Use collected revenue for cash results. Use invoice value for a sales or billing view. Label the measure so the team does not mix them.
