Peppol comes up in every conversation about e-invoicing. Here is the essential to understand what it is, without the jargon.
Key takeaways
- Peppol is a network, not a piece of software: it routes documents between businesses.
- The four-corner model separates sender, access points, and recipient.
- You connect once; you reach every recipient on the network.
A network, not a single format
Peppol is often mistaken for a file format. In reality, Peppol combines a document format (Peppol BIS, based on UBL 2.1) and a secure transport network that links businesses through access points.
The four-corner model
- 1
Corner 1: the sender
The business that creates the invoice in its software.
- 2
Corner 2: its access point
It puts the invoice into the Peppol format and sends it onto the network.
- 3
Corner 3: the recipient's access point
It receives the invoice and passes it on.
- 4
Corner 4: the recipient
It receives a structured invoice, ready to be processed.
