Peppol messages are business documents, such as an invoice or an order. Each is exchanged according to a specification:

UBL describes the XML structure of a document.
A BIS (Business Interoperability Specification) sets the rules for an exchange.
PINT is an international billing model that individual countries specialise.

The tree lists every active document type in its official OpenPeppol category, exactly as in the reviewed code list. Choose a category or a document type to see its identifiers and processes, followed by a plain-English explanation of the document. The explanations are written for this site and don't change the official classification.
