How to Track Job Costs in Real Time and Protect Your Margins

The 6-Step Process

Each industry guide below follows this same framework, adapted for the specific context of that industry.

1. 1

   Define Your Direct Cost Categories for Every Job Type

   Job cost tracking starts with knowing what costs you are tracking. Define direct cost categories: materials (parts, consumables), labor (regular, overtime, drive time), subcontractor costs, equipment rental.

2. 2

   Capture Labor Time at the Job Level — Not the Day Level

   Daily timesheets that capture total hours do not allow job-level cost analysis. Labor must be captured by job: clock in on Job A, clock out, clock in on Job B. GPS-based field time capture makes this automatic.

3. 3

   Require Parts to Be Logged Against a Job Before Installation

   Parts pulled from a truck and installed without being logged against a specific job are invisible costs. Require part logging at time of installation — not at day's end — so the job cost is accurate before the tech leaves the site.

4. 4

   Set Up Cost Budgets for Your Most Common Job Types

   A furnace replacement should have a known cost budget: X in materials, Y in labor hours. Compare each completed job against its budget. Jobs that run over budget have either a mis-estimate, mis-execution, or a systemic cost problem.

5. 5

   Review Job Cost vs. Job Revenue Weekly — Not Quarterly

   Quarterly P&L analysis reveals that jobs were unprofitable three months after the fact. Weekly job cost review — comparing actual cost to invoiced amount for the prior week's closed jobs — catches margin problems while the pattern is fresh.

6. 6

   Identify Your Top 5 and Bottom 5 Job Types by Margin

   Six months of job cost data reveals your best and worst job types by profitability. This analysis often reveals that the jobs your sales team pushes hardest are not the jobs making the most money.
