Rules
Fixed thresholds and comparisons, set with you before go-live. Cheap to run, always the same answer, and explainable line by line to an auditor or a judge.
- A payment declared on the 12th that is not in the bank by the 20th.
- Invoice 4471 registered twice, the second copy already queued for payment.
- A document over the agreed threshold with no second signature.
- A shelf price of 1.89 against a cost of 1.95.
