Peppol BIS Invoice Response is a business-level response that a buyer can send to a supplier after receiving an invoice or credit note. It communicates the buyer’s processing status and can include reasons or requested actions.
The standard status codes include:
- AB: acknowledged
- IP: in process
- UQ: under query
- CA: conditionally accepted
- RE: rejected
- AP: accepted
- PD: paid
Invoice Response is not a transport acknowledgement and does not report network delivery. Transport receipts and eDelivery status messages operate at different layers. Message Level Response or Message Level Status concerns technical or message-level processing, while Invoice Response reports the buyer’s business handling of the invoice.
The message is based on OASIS UBL 2.1 ApplicationResponse and is validated with the applicable Peppol rules.
See the official Peppol BIS Invoice Response documentation and the overview of Peppol message types.
