The project ‘Introduction of e‑invoicing in the Federal Administration’ is an important part of the 9-point plan for digitalisation by State Secretary Dr Richter and was recognised as a flagship project of the Procurement Office of the Federal Ministry of the Interior (Procurement Office).

Digitalisation and automation of business processes are increasingly becoming part of everyday business operations. The federal project ‘Introduction of e‑invoicing in the Federal Administration’ is a catalyst for digital business processes in the B2G context and was named a Procurement Office flagship project by State Secretary Dr Richter. It establishes an efficient and sustainable connection of the economy to the invoice receipt platforms of the Federal Government as a basis for stable, error‑free, seamless and user‑friendly submission of e‑invoices. It lays the foundation for complete digitalisation of internal processes from tendering or order placement to invoicing and payment. In addition, established standards, such as XRechnung, and European networks (e.g. Peppol) are used to ensure a uniform economic area and efficient cross‑border trading.

Diagram showing the structure of the project “Introduction of E-Invoicing in the Federal Administration”. The structure is presented as four concentric circles. In the innermost circle are “companies” and the “administration”, which form the foundation of the structure. In the next circle consists of three sections: “liquidity”, “transparency” and “efficiency”. The next circle shows “E-invoicing in the context of the Online Access Act (OZG)”, which in turn is the basis for the following sections in the outer circle: 1. Security, 2. Sovereignty, 3. Any time, anywhere, 4. Unternehmenskonto Bund, 5. E-Procurement, 6. Electronic records management, 7. Digital expertise.
