What is a duplicate invoice and how do you prevent duplicate payments?

Intermediate

Answer

A duplicate invoice is the same invoice entered more than once (e.g., resent by the supplier or scanned twice), risking a double payment. Prevention includes enforcing unique supplier+invoice-number checks in the ERP, matching to POs/receipts, blocking payment of unapproved items, and running duplicate-detection reports before each payment run.
Real-world example The ERP rejects a re-keyed invoice because the supplier ID and invoice number already exist, preventing a $8,400 double payment.
