E-invoicing in Germany
Germany has introduced a B2B e-invoicing mandate to be fully effective from the 1st of January 2028 onwards, following the EN 16931 standard from the European Committee for Standardisation (CEN) and ViDA initiative. This means that Germany will gradually transform towards a more regulated e-invoicing model in the future.
B2B e-invoicing
Germany is today in a post-audit model with e-invoicing, where businesses independently manage the creation, transmission, receipt, storage, and reporting of invoices (including VAT), without direct involvement from tax authorities.
In B2B e-invoicing various standards and networks, such as Peppol, are already used, but a large number of companies still rely on email. The commonly used method is to send e.g. ZUGFeRD (PDF with XML data layer) and e.g. XRechnung (pure XML) invoices via email. Large volumes are exchanged as traditional EDI.
B2G e-invoicing
B2G e-invoicing is subject to more regulation compared to B2B. While it is mandatory for the federal government, there are existing alternative approaches that make it decentralized.
The two primary access points for receiving B2G e-invoices from suppliers at the federal government level are the ZRE and OZG RE platforms. However, at the state level, each state has the autonomy to decide whether to use the central government platform, adopt alternative systems, or not implement any system at all.
Closer look at B2G federal platforms
B2G e-invoicing was made mandatory at the federal level in early 2020. Only invoices compliant with EN 16931 standards can be sent to the government. The official e-invoice format for B2G e-invoices is XRechnung, with ZUGFeRD also utilized, primarily because of its compatibility with EN 16931 standards.
When sending electronic invoices to a government entity, a unique buyer reference known as the “Leitweg-ID” is necessary for identification and addressing purposes. While invoice issuers themselves do not require their own buyer reference, the Leitweg-ID must be obtained from the relevant government body.
Sending invoices via ZRE and OZG RE platforms can be accomplished through various methods, including manual data entry on these platforms, email transmission, manual upload, or via Peppol. Technically, you have the option to connect directly to these federal government platforms or utilize a service provider to deliver invoices to the government on your behalf.
ZRE and OZG-RE for delivering e-invoices
ZRE – Zentrale Rechnungseingangsplattform:
- Designed for submission of e-invoices, providing a streamlined process for suppliers to send invoices to the government.
- The federal government and e.g. district authorities require invoice submissions via the ZRE portal.
OZG-RE – Onlinezugangsgesetz-konforme Rechnungseingangsplattform:
- Very similar to ZRE in practice, the main difference is who is reachable via the platform.
- Institutions that are associated with the Federal government, for example, require invoice submissions via the OZG-RE portal.

B2B mandate impact and timelines
Starting from the beginning of 2025, every company in Germany must be ready to receive e-invoices compliant with the EN 16931 standard, such as XRechnung or equivalent formats. Invoice issuance will be mandated in three primary phases also starting in 2025. The Germany mandate applies to domestic invoicing, marking the definitive end of paper-based invoicing entirely from 2028 onwards.
The upcoming changes in electronic invoicing regulations starting from January 2025 will bring both opportunities and challenges for businesses. With suppliers gaining the authority to issue EN-compliant e-invoices to buyers without prior consent, there’s potential for a smoother transition to electronic invoicing, potentially reducing the resources required for accounts receivable.
The coexistence of paper invoices and non-EN-compliant formats alongside EN-compliant e-invoices will keep accounts payable processes complex for some time. However, exchanging invoices in unstructured formats or non-EN-compliant EDI will require prior approval from the buyer.
Starting January 2027, companies with turnovers exceeding €800K will be mandated to send only EN-compliant e-invoices. Smaller companies will have the option to continue sending paper or PDF invoices until January 2028, after which all companies must transition to sending only e-invoices.
