What is the difference between the federal administrative portal and the two federal invoice submission portals, the ZRE and the OZG-RE?
To find the ZRE and OZG-RE on the federal portal, enter “ZRE” in the search field of www.verwaltung.bund.de. You will then be taken to the page “Transmit invoices electronically via e‑invoice platforms”. Click on the text or on the word “More”. On the new page, click on “Forms & Online Services”. Under “Related Links”, you will find links to the ZRE and OZG-RE and any other available invoice submission platforms.
