Questions about Peppol

Do I need an access point?

To send through the Peppol network, yes. Quittio creates the valid file; a certified provider handles the transport.

No. In Germany, ZUGFeRD or XRechnung are sufficient. Peppol is an additional channel used by some authorities and international customers.

When which invoice becomes mandatory is explained in our guide to the German e-invoicing mandate.
