Question

Accepted Answer

Duplicate payment scenarios in 2 way match and 3 way match involve matching invoices with purchase orders and receiving documents.

In a 2 way match, the invoice is matched with the purchase order to ensure the correct amount was billed.
In a 3 way match, the invoice is matched with the purchase order and receiving documents to verify that the goods or services were received.
Duplicate payment scenarios can occur if the same invoice is processed and paid multiple times.
Examples of duplicate payment scenarios include processing the same invoice twice due to system errors or human error.
To prevent duplicate payments, P2P specialists should implement controls such as invoice matching and approval workflows.
