Invoice Receipt Platform
Definition
An invoice receipt platform is a digital system through which companies and public bodies receive, validate, and further process electronic invoices. For the federal administration this has been OZG-RE alone since 19 September 2025; states and municipalities use either OZG-RE or platforms of their own. Platforms check incoming invoices for compliance with the XRechnung standard and route them to the responsible unit within the authority.
