Duplicate Payment Recovery
Duplicate payments often hide behind small differences in invoice numbers, payment dates, vendor names, entities, or locations. Recovery depends on proving that the second payment was not already refunded, credited, or offset.
- Match on amount, service period, vendor account, PO, shipment, and invoice references instead of invoice number alone.
- Confirm whether the second payment was refunded, credited, offset, voided, or still open.
- Package the evidence before asking the vendor for confirmation.
