The happy path is rarely where POS finance modules fail. We build a short catalogue of exceptions—void after approval, reversal after funding request, timeout mid-disclosure, supervisor force-post—and test what the ledger and the customer copy then show. Residual tickets and silent approvals are listed with the control that should have caught them.
What is included
- Catalogue of void, reverse, timeout, and force-post paths
- Sample tests in a lab till or supervised store window
- Residual balance and orphan-approval search
- Recommended dual-control points for high-risk exceptions
How we start
After your note we confirm the module family, whether we need a live till or a lab environment, and the sample window. The figures on this page are for planning. There is no online payment.
