What job profit needs before you trust the margin
A job can look profitable while important costs are still missing. Use this closeout review before treating the margin as final.
Revenue alone does not explain the result
A completed invoice can make a job appear profitable before the cost side is complete. Reliable job profit needs the final approved revenue and the costs required to deliver it.
Start with the invoice total after discounts and taxes are handled according to your reporting policy. Payments affect cash collection, not the underlying job revenue: an unpaid invoice can still represent earned revenue, while a deposit is not additional revenue.
Capture labor consistently
Use actual time when the team records it. Include the loaded hourly cost the business uses for job costing, not the customer billing rate. If time is missing, an estimate can be a temporary signal, but it should be labeled as estimated rather than blended silently with actual cost.
Review unusually long shifts, overlapping entries, open timers, and work recorded by people who were not assigned. These are often simple entry mistakes that can materially change the margin.
Include materials from every path
Materials can enter the job through inventory reservations, received stock, purchase receipts, and manual expenses. Make sure the same purchase is not represented twice—for example, once as an inventory issue and again as the full supplier receipt.
Use the cost basis recorded when stock is applied to the job. If a supplier price changes later, historical jobs should not silently inherit the new price.
Review approved changes and discounts
Field changes are easy to document in notes but forget on the invoice. Compare the completed work, photos, updates, and approved estimate. Confirm that approved additions are billed and that removed work or promised discounts are reflected.
Treat the margin as final only after closeout
A useful closeout review checks:
- Final invoice amount and approved changes
- Labor time and cost
- Inventory and direct purchases
- Refunds, discounts, or credits
- Completion notes and photos
- Any remaining unbilled or disputed work
Until those are reviewed, label the result as a current estimate. Once they are complete, the job record becomes useful beyond that one project: it can improve future estimates, staffing decisions, reorder planning, and pricing conversations.
