What is Peppol?

Peppol is an international network and set of standards for exchanging business documents (invoices, orders, credit notes) between organisations across country borders.

Peppol (Pan-European Public Procurement On-Line) is an open, international e-procurement network governed by OpenPeppol, a non-profit association. It provides a framework of technical specifications — transport, document formats, and directory services — that let any two businesses exchange invoices, orders, and other business documents regardless of the software they use.

The Peppol network uses a four-corner model: the sender's access point delivers the document to the receiver's access point, with both access points registered in the Peppol directory (SMP/SML). Buyers and sellers are identified by Peppol Endpoint IDs, often derived from VAT numbers. You don't send directly to a trading partner — you publish your endpoint in the directory and receive documents through your registered access point provider.

The main e-invoicing format on Peppol is Peppol BIS 3.0 (Business Interoperability Specification), which is a profile of UBL 2.1. It adds Peppol-specific validation rules and mandatory metadata (EndpointID, PartyTaxScheme, etc.) on top of the base UBL schema. Most EU public-sector e-invoicing and a growing share of B2B invoicing uses this format.

Invotify Pro generates Peppol BIS 3.0 XML files, including EndpointIDs when a customer's Peppol ID is stored. Invotify does not operate a Peppol access point — you deliver the generated file through your country's registered access point providers. To receive invoices on Peppol you also need a registered access point.

Frequently Asked Questions

Q01

What is Peppol and who runs it?

Peppol (Pan-European Public Procurement On-Line) is an international network and set of standards for exchanging business documents such as invoices, orders, and credit notes between organisations across borders. It is governed by OpenPeppol, a non-profit association, and is used by public authorities and businesses across Europe, Australia, Singapore, and beyond.

Q02

How does the Peppol network actually work?

Peppol uses a four-corner model: a sender connects through their Access Point, the document travels over the secure eDelivery network, and the receiver collects it through their own Access Point. Each participant has a unique Peppol identifier, so documents are routed reliably without both parties sharing a direct connection.

Q03

What format do Peppol invoices use?

The standard business format is Peppol BIS Billing 3.0, which is built on UBL 2.1 XML and conforms to the European standard EN 16931. This means a Peppol-compliant invoice is also EN 16931-compliant, making it valid for e-invoicing mandates across the EU.

Q04

Does Invotify support Peppol?

Yes. On the Pro plan, Invotify can export your invoices as Peppol BIS Billing 3.0 XML, ready to send through a Peppol Access Point. The same engine also produces UBL 2.1 and CII output, so you can meet most European e-invoicing requirements from a single document.
