To transmit an e-invoice to the authorities of the direct Federal Administration, the invoice receipt platform ZRE must be used. The ZRE platform assumes the following three tasks for the transmission of e-invoices:
- The receipt of e-invoices via various transmission channels.
- The technical verification of e-invoices (including invoice size, number and type of attachments, virus check, entry of all mandatory information)
- The transmission of e-invoices to the respective invoice recipient via buyer reference.
