A public or private contracting authority can also connect to an existing Peppol service provider, which means they do not need to set up and operate their own Peppol Access Point (or their own SMP server) to be able to accept electronic invoices, specifically XRechnung invoices, from the Peppol network. Peppol service providers provide their contracting partners with various interfaces to enable retrieval of the invoices received.

An up-to-date list of existing Peppol service providers (Access Point and SMP), can be found on the Certified Peppol Access Points (APs) page.
