Check your French e-invoicing calendar in 2 minutes: e-invoicing, e-reporting and the actions your business needs to prepare.
From September 1, 2026, receiving electronic invoices becomes mandatory for every business established in France and registered for VAT; issuing follows in waves: large and mid-sized enterprises (ETIs) in 2026, then SMEs and micro-enterprises in 2027.

You can demonstrate compliance with certification from an accredited body or an attestation from the software publisher. After the 2025-2026 legislative reversal, publisher attestations remain valid for online and in-store sellers.
