Since 2025, e-invoicing has become increasingly important in B2B transactions: structured electronic invoices enable automated processing, less manual work and greater legal certainty.

E-invoicing mandate 2026: What companies need to know now

19. June 2026

Less red tape, lower costs, and faster payment processing: Germany’s e-invoicing mandate is driving the digitalization of accounting and invoicing. Since January 1, 2025, companies in Germany have been required to receive electronic invoices in B2B transactions. E-invoicing is therefore no longer a future topic, but part of everyday business. Companies should now check whether their software supports current requirements and formats such as XRechnung 4.0 and ZUGFeRD 2.5.

The ZUGFeRD format combines a readable PDF invoice with embedded XML data, supporting efficient digital invoice workflows.

The ZUGFeRD format combines a readable PDF invoice with structured XML data.

Learn more about its benefits, how it differs from XRechnung, and the continued development of ZUGFeRD 2.5.

Since November 27, 2020, incoming invoices have only been accepted in electronic invoice format. This means that paper invoices and PDF invoices are accepted only in exceptional cases. The introduction of XRechnung was certainly a milestone — but was it a step forward or a step back?
