Dated supplier statement, vendor ledger, invoice copies, credit notes, remittance evidence, currency and cutoff date.
Workflow
- Confirm vendor, currency and the same cutoff date before comparing balances. Capture opening balances and movement totals.
- Match invoice, credit and payment references without silently merging repeated invoice numbers. Preserve unmatched items.
- Explain differences only from evidence: an issued payment not received can be a timing item, while a wrong recorded invoice amount needs correction review. Missing documents stay unknown.
- Return an exception register and a balance bridge. Do not pay a supplier, send a dispute or edit a ledger. A qualified owner reviews any correction.
Output contract
reference | statement amount | ledger amount | difference | evidence | timing/error/unknown | reviewer | next check
Fictional acceptance test
Fictional vendor statement closes at $1,200 and the ledger at $900. A $300 payment recorded in the ledger on cutoff day has a bank reference but is not on the supplier statement. Statement $1,200 minus the timing payment $300 equals ledger $900; the item remains pending supplier confirmation, not an invented invoice error.
Review gates and limits
Recompute the $300 bridge, check cutoff and duplicate references, and verify that a payment in transit is not counted twice. If evidence is removed, the explanation becomes unknown.
