Peppol aims to interconnect senders and recipients of electronic documents. Both the sender and recipient need an access point to access the Peppol network.
The invoice sender sends their invoice to an access point which connects to the recipient’s access point by means of the Peppol receiver ID. Once the e-invoice is received by the recipient’s access point, it is made available to the recipient. The invoice submission portals ZRE and OZG-RE are connected to the access point of the recipient (the authorities). Within the submission portals, the buyer reference (Leitweg-ID) is then used for addressing the invoices to the various authorities. Once suppliers have registered their customer’s Peppol receiver ID with the relevant submission portal and activated Peppol, they can send their e-invoices via Peppol to the invoice submission portals. The authorities connected to the system can thus retrieve e-invoices submitted via Peppol from their submission portal and process them in their systems as usual.
