E-invoicing for authorities of the federal administration

You can find numerous tips here to help your suppliers make the transition to electronic invoicing.

What government authorities need to know about e‑invoicing

A quick overview

  • Since 27 November 2020, invoice issuers have been required to use invoices in electronic form (e-invoices) when billing federal authorities (contracting authorities) for goods and services delivered (see section 3 of the E-Invoicing Ordinance (E-Rechnungsverordnung, ERechV)).
  • There are two federal portals for submitting e-invoices. Organisations of the direct federal administration receive e-invoices via the Federal Central Invoice Submission Portal (ZRE). Many organisations of the indirect federal administration receive e-invoices via the federal Online Access Act-compliant Invoice Submission Portal (OZG-RE).
  • It is very important for federal authorities to inform their suppliers, as this is the only way for both parties to benefit from the advantages offered by electronic invoicing (e-invoicing).
  • Through the so-called “supplier information”, authorities ensure that their service providers and suppliers receive all the necessary information for electronic invoicing from 27 November 2020.

How is e-invoicing organised at the federal level and in Germany’s federal states?

The federal E-Invoicing Ordinance governs the sending of e-invoices by suppliers to the federal administration. Germany’s federal states implement EU Directive 2014/55/EU under their own responsibility.
