Prove the costing engine before you rely on it: recreate known results, then test blind.
Stage 1 — Recreate Known Results
Upload a manually prepared workbook; the engine recalculates from source data and explains every difference.
| High School Graduation 2025 | $214,800 | $57,639 | -$157,161 | -73.2% | Manual workbook excluded employer workers' compensation. |
|---|---|---|---|---|---|
| Orange City Community Festival (OC 2026) | $158,200 | $40,818 | -$117,382 | -74.2% | Manual workbook applied current rates rather than work-date rates. |
| Special Detail — Speedway Weekend | $96,400 | $48,495 | -$47,905 | -49.7% | Manual workbook allocated an entire pay period to the event. |
Variances must be explained before an analysis is certified. The three explanations above are the classic manual-process differences: omitted employer burden, current-rate substitution, and whole-pay-period allocation.
