Use case / Job economics
Understand where job costs are drifting.
Bring recorded labor, materials, and outside work alongside the estimate to find the variance worth reviewing.
Compare costs with the same scope
A useful cost review compares the approved estimate with recorded costs for the same job, quantity, and cost categories. Separate labor, material, machine time, scrap, and outside processing where those fields exist. Identify whether the estimate covers the entire order or only an operation before interpreting a difference.
Recorded cost can lag production. Time entries may await approval and an outside-process invoice may arrive after the work returns. Display the comparison date and the posting state. An open job’s total should be described as recorded cost to date, with missing categories visible, so a partial number is not mistaken for a finished-job result.
Illustrative sample: labor variance with an open invoice
This fictional cost record uses sample dollars. Job WO-4107 has estimated labor of $600 and recorded labor of $720. The $120 difference prompts a review of setup time, quantity, and the rate applied. It does not by itself explain whether the job is unprofitable.
Materials show $400 estimated and $380 recorded, while outside processing has a $250 estimate and no posted invoice. Keep the outside-processing category marked incomplete. Adding the two posted categories produces $1,100 recorded to date, which should not be presented as a final total against the $1,250 estimate. The estimator and accounting owner should confirm the comparison basis.
| Category | Sample estimate | Sample recorded | Review state |
|---|---|---|---|
| Labor | $600 | $720 | Review $120 variance |
| Material | $400 | $380 | Confirm all issues posted |
| Outside processing | $250 | Invoice not posted | Incomplete |
Keep rates, quantities, and allocations inspectable
The mapping should connect estimate revision, job ID, produced quantity, time entries, labor rates, material issues, scrap, and outside-work transactions. Record the currency and the basis for each rate. If overhead is included in the estimate, confirm whether recorded actuals apply an equivalent allocation.
Avoid combining purchase commitments with invoices as though both were separate actual expenses. Distinguish standard cost from posted cost and preserve adjustment or reversal records. A reviewer should be able to follow a variance back to its entries. Refresh after agreed posting milestones rather than implying every expense appears as soon as an operation ends.
Assign financial interpretation to the right owner
Operations can investigate additional setup time or scrap; estimating can check assumptions; accounting should validate rates, posting completeness, and allocations. A proposed answer can organize that review while leaving the financial system responsible for official cost records. Any corrections need the existing authorization process.
Start with a closed job whose costs the team has already reconciled, then test an open job with known missing entries. Agree on what “complete” means before showing final comparisons. SPOF’s job-costing scope depends on the fields made available and their mapping. Accounting should confirm posting completeness and allocation rules before the team uses the comparison for financial decisions.
