What's new?​

The French outbound B2B e-invoicing flow is live: registered customers can submit domestic B2B e-invoices through efsta and the Iopole platform. Submissions carry the mandatory French invoice content, retries are protected against creating duplicate invoices, and every submission is logged with traceable identifiers — validation or technical failures surface as clear, user-facing outcomes instead of silent errors.

Around the core flow:

  • The portal shows your French onboarding state explicitly — Registering until directory registration completes, then Registered — and invoice actions stay safely blocked until you are registered.
  • A dedicated French test environment runs alongside production, so partners can complete onboarding and send end-to-end test invoices with test data fully isolated from production.
  • The Peppol validation service now stays warm in all environments, eliminating cold-start delays on validation requests.

What this means for our users?​

France's e-invoicing mandate is approaching, and you can now build and verify your outbound flow end-to-end — in test mode, against the real API — before going live. Clear registration status means no guessing about when you can start billing, and duplicate protection means a retried submission never becomes two invoices at the tax platform.
