The EDI 820 is an electronic file format that establishes the data content of the payment order/remittance advice transaction set within the context of an Electronic Data Interchange (EDI) environment. This standard transaction set is used to transmit remittance and/or payment information to a bank with instructions to begin funds transfer. Using the EDI 820 transaction set to electronically transmit data between business partners enables consistent interpretation of payment information and reduces the chances of interpretive and data entry errors.
