Definition
OZG-RE stands for OZG-compliant invoice receipt platform, the federal government's platform for receiving electronic invoices. It is operated by Bundesdruckerei. Since the ZRE was switched off on 19 September 2025, it has been the only federal invoice receipt platform: it receives invoices for the entire direct federal administration, for more than 170 bodies of the indirect federal administration and for currently five federal states (as of September 2025). Invoices can be submitted by web form, upload, Peppol or email, among other channels. The name refers to the Online Access Act (OZG).
