The introduction of e-invoicing for the B2B is planned to start in Germany in January 2025. However, it is not yet decided if all companies will have to switch to e-invoicing at the same time (January 2025) or an implementation in stages will take place.
The German project stipulates that electronic invoices will have to comply with the EN 16391 standard, which establishes the requirements for the European invoice. Currently both formats XRechnung and ZUGFerD are compliant with the EU regulation.
