Frequently Asked Questions
What net profit margin should a contractor target?
Healthy contractors net 8–15% after paying themselves a market salary. Gross margins need to run 25–35% to get there once overhead takes its 15–25% share.
Why do profitable-looking jobs lose money?
Unbilled change work, labor overruns, callbacks, and forgetting overhead allocation. Job-level profit reviews within a week of completion catch the pattern while memory is fresh.
What is the difference between gross and net profit on a job?
Gross profit is price minus direct job costs. Net subtracts your overhead share — office, trucks, insurance, estimating time. A job can be gross-positive and still net-negative.
