One Payment, Four Stories
Did each sale, settlement and refund reach the right amount, status and destination?
Narrative sequence
- Four witnesses — One fictional payment retains identity while four system witnesses appear.
- Candidate alignment — Candidate copies align on reference, amount, date, status and destination.
- Exception closure — Exact matches close; duplicates, late records, orphans and wrong destinations stay open.
- False pass — The amount/date baseline falsely passes a payment posted to the wrong ledger account.
- Tightened key — Destination and category tighten the key and overturn the false pass.
- Separate economics — Revenue, cash and contribution remain separate quantities.
- Exception lanes — Mature exceptions enter resolve, investigate or UNKNOWN lanes.
| Evidence | Value | Status / meaning |
|---|---|---|
| Bank ↔ ERP | match | amount + date |
| Bank ↔ Gateway | match | reference |
| Bank ↔ Ledger | review | destination |
| Exception 014 | R48,620 | human review |
Trivial baseline
Coarse matcher: amount and date agree, so the payment is treated as reconciled.
Sensitivity
Extend the settlement maturity window and toggle destination, category and status dimensions; timing-only differences shrink while wrong postings remain.
Strongest counter-case
A difference may be timing, while a match on amount and date may still hide a wrong account.
Verdict
SURVIVES: destination-aware exception. DOWNGRADED: gross exceptions are not recoverable savings.
Synthetic example. Deterministic fictional records; not customer data or achieved customer results.
