Small shops often wait until the job is done to check margin. By then, it is too late to fix anything. Job costing for small contractors is simply watching sold price versus real cost while work is still in progress.
Compare sold price and planned costs against actual spend as work progresses. Catch problems while you can still pause extras, renegotiate, or issue a change order.
Approved change orders change both sold price and cost. A job-cost view that ignores them lies to you. Live margin should include every approved extra automatically.
You do not need payroll modules or deep accounting to answer “Is this job making money?” Specialty contractors need budget vs actual, committed spend visibility, and margin alerts when numbers slip.
At closeout, summarize sold price, cost, margin, and change-order impact. That recap trains your next bid and shows where verbal extras still leak profit.
