What is a Peppol access point and how does it work?
A Peppol access point (AP) is a certified service provider that connects to the Peppol network and enables businesses to send and receive Peppol-compliant e-invoices and other business documents. Access points act as gateways between a business's internal systems and the Peppol four-corner network, handling document transport, format transformation, and protocol compliance.
How is a Peppol access point certified?
Peppol access point certification: (1) The service provider applies to the relevant Peppol authority (OpenPeppol for most regions); (2) The provider implements the Peppol AS4 transport protocol specification; (3) The provider passes interoperability testing against the Peppol test suite; (4) The provider signs the Peppol Transport Infrastructure Agreements; (5) The provider receives a Peppol PKI certificate; (6) The provider is listed in the Peppol directory. Ongoing certification maintenance requires periodic compliance re-testing and adherence to Peppol technical and operational requirements.
Frequently Asked Questions
- Can a business operate its own Peppol access point?
- Yes. Large businesses with high e-invoice volumes may choose to operate their own certified Peppol access point rather than using a third-party provider. Self-hosting an access point requires implementing the AS4 transport protocol, obtaining Peppol PKI certificates, passing OpenPeppol certification, and maintaining ongoing compliance with Peppol specifications. Most businesses use a third-party access point provider to avoid this technical and certification overhead.
- How does a Peppol access point handle document format transformation?
- Many Peppol access points offer format transformation services: they accept documents in the customer's native format (e.g., proprietary ERP XML, CSV) and transform them into the required Peppol document type (e.g., UBL 2.1 BIS Billing 3.0 for invoices). On the receiving side, they transform incoming Peppol documents into the recipient's ERP format. Transformation capabilities and mapping quality vary by access point provider and are a key selection criterion.
