Peppol (Pan-European Public Procurement Online) emerged from an international project aimed at standardising public procurement and contract award procedures in the European Union and globally. Peppol is run by OpenPeppol AISBL, a Brussels-based non-profit organisation established under Belgian law.
Peppol essentially pursues the vision of creating full interoperability across different systems. This means that any business in a given country should be able to manage all procurement and contract award procedures electronically, whether it be with an administration located in the same country or abroad. For this purpose, Peppol provides a data transmission network (the Peppol eDelivery Network) and specifications for the documents to be transmitted (Peppol Business Interoperability Specifications, BIS). The main advantage offered by this organisation is the entirely electronic, seamless and automated exchange of documents. Peppol also supports the automated mass import of documents.
The invoice submission portals ZRE (for the direct federal administration) and OZG-RE (for the indirect federal administration) as well as the cooperating federal states use the Peppol network to enable suppliers to automatically submit their e-invoices.
Technically speaking, Peppol is based on what is known as the “four-corner model”.
