Things are getting serious: e-invoicing is to become mandatory in Germany. According to the current draft legislation, taxable persons will still be able to "test” the system until the end of 2025, but as of January 2026, e-invoices will have to be exchanged for all domestic B2B transactions between taxable persons established in Germany. There are currently no guidelines on how e-invoices are to be exchanged. Now, the task is to analyze and adapt invoicing processes and make ERP systems fit for the new e-invoicing obligation.
