Germany is one of the countries with varying obligations regarding the electronic invoicing. Although in the future it is planned to standardize the obligation of e-invoicing by introducing the CTC model, there are still legal differences in individual Länder (states).
The authorities of Mecklenburg-Western Pomerania announced mandatory e-invoicing in the B2G area from April 1, 2023. As before, it will be done via the OZG-RE platform. This possibility has existed since April 18, 2020.
