Procurement Approval Threshold Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Approval path is selected by comparing purchase amount with requester, manager, procurement-review, and executive thresholds. Amount over requester limit = max(0, purchase amount - requester limit).
