The PEPPOL network and standard enable you to connect to your trading partners internationally via PEPPOL Access Points like OpusCapita.

What is PEPPOL?

PEPPOL (Pan-European Public Procurement Online) is an interoperability infrastructure, co-funded by the European Commission and 18 government agencies. The goal is to simplify and standardize the B2G and B2B exchange of e-invoices, e-orders, and other supply chain documents.

PEPPOL strives to standardize on three levels: routing, document specifications, and network infrastructure.

“PEPPOL has the potential to become the standard for all business messaging.”

The fundamentals of the EESPA and PEPPOL infrastructures are explained by Ahti Allikas, our e-invoicing expert and a member of EESPA, PEPPOL, and more.

Process The PEPPOL network

PEPPOL easily connects you to other trading partners who are also using PEPPOL, eliminating the need to set up direct connections.

In addition to the cost savings and better accuracy from switching from paper to electronic, the PEPPOL BIS Billing format has become the standard in many countries. While this makes PEPPOL a compliancy requirement, it also simplifies the exchange of electronic documents internationally.

How PEPPOL network works

OpusCapita is a certified PEPPOL Access Point


The sender sends an electronic document (an e-invoice, e-order, etc.) via their Access Point provider.


The Access Point typically validates the document and identifies the recipient’s Access Point.


The sender’s Access Point delivers the document to the recipient’s Access Point via the open network.


The recipient’s Access Point delivers the document to the recipient.

With our Business Network solutions, you can use the OpusCapita Access Point as one interoperability option to exchange documents with your trade partners that use other Access Point providers.

PEPPOL identifiers

Senders and receivers in PEPPOL are identified using ISO6523 identifiers. Depending on the country, they are organization IDs, VAT IDs, public sector IDs, etc.

To send electronic documents via PEPPOL, your receiver’s identifier must be found in the routing of the document. Similarly, to receive documents, your identifier must be found in the routing. OpusCapita Routing Service automatically handles this for you.

PEPPOL e-invoicing

PEPPOL BIS Billing 3.0

PEPPOL processes are specified in documents called Business Interoperability Specifications (BISs), and one of them is PEPPOL BIS Billing.

OpusCapita solutions come with in-built support for PEPPOL e-invoicing, transforming the AR invoice data from your ERP format to PEPPOL BIS Billing 3.0, and delivering it via PEPPOL whenever it’s the recipient’s preferred delivery method. Similarly, when you receive PEPPOL invoices from your suppliers, we transfer them into your workflow system, and transformed them into your preferred e-invoice format.
