In six days, B2B e-invoicing becomes mandatory in France. On September 1, 2026, every VAT-registered business operating in France must be capable of receiving electronic invoices through a licensed Approved Platform (PA — Plateforme Agréée). Mid-sized companies (ETI) and large enterprises also face a mandatory sending obligation from that date. SMEs have a deferred sending deadline — but not for receiving. The reform affects more than 10 million economic actors (Service-Public Entreprendre, August 2026).
If your organisation has a French subsidiary, French suppliers, or French customers, this deadline directly affects your ERP and finance operations.
Background: A Reform Long Delayed, Now in Force
France’s B2B e-invoicing reform was postponed twice — originally planned for 2024, then delayed to 2025 — before landing on this final schedule. The architecture rests on a network of licensed Approved Platforms (PAs, formerly called PDPs — Plateformes de Dématérialisation Partenaires) and a government portal (PPF — Portail Public de Facturation) managed by the French tax authority (DGFiP). As of July 1, 2026, 137 active PAs were listed in the official directory (July 2026 review).
Three formats are recognised by French tax authorities for a compliant electronic invoice: Factur-X (a hybrid PDF+XML format, the most widely adopted in France), UBL (Universal Business Language, the same standard used in the Peppol network across Europe), and CII (Cross Industry Invoice). A plain PDF sent by email is not an electronic invoice under this reform, regardless of how it is formatted.
What Changes in Practice for Your Organisation
The receiving obligation applies to all businesses without exception. From September 1, any ETI or large enterprise supplier is both entitled and required to send you invoices in structured format via an approved PA. If your ERP or accounting software is not connected to a PA and cannot ingest a Factur-X or UBL data stream, your accounts payable team will receive invoices it cannot process through its normal workflow. This is an immediate operational risk — even for an SME that has a deferred sending obligation.
For mid-sized companies and large enterprises, sending is also mandatory. Customer invoices must be issued in structured format and transmitted through your PA to your customer’s PA — or directly via the PPF government portal. A Word-generated purchase order exported to PDF remains legally insufficient from September 1 onward.
SMEs have a deferred sending deadline until September 1, 2027, but that extension does not cover receiving. An SME that has not connected its PA to receive invoices will be in breach of the regulation if it rejects or ignores an electronic invoice sent by a compliant supplier.
Major ERP vendors have anticipated the reform. Cegid, Sage, Divalto, and Axelor are registered as dematerialisation operators or connected to licensed PAs (les-aides.fr, 19 August 2026). Businesses still running an ERP with no PA connection — or using informal invoicing tools (Excel, legacy software without an e-invoicing module) — face immediate risk.
Penalties
Fines are graduated by type of non-compliance (Service-Public Entreprendre):
- €500 per business for failure to connect to a licensed Approved Platform
- €15 per non-compliant invoice issued outside the PA network
- €250 per breach of e-reporting obligations (transmission of B2C and international transaction data to the DGFiP)
Fines apply per invoice and per breach — not per company. The Belgian experience with mandatory Peppol adoption is instructive: 17% of businesses were still outside the network three months after the deadline, and the tax authority accumulated significant penalties on monthly invoice volumes that went unprocessed.
Operational Checklist — 6 Days Out
Before September 1, verify each point with your CIO and CFO:
- Is your ERP or invoicing software connected to a licensed PA? Check the official DGFiP directory to confirm your PA is listed.
- Have you tested receiving a Factur-X or UBL invoice end-to-end? A full end-to-end test with a supplier or a PA test feed is essential before the deadline.
- If you are an ETI or large enterprise: have you sent a test invoice via your PA? Sending requires your SIRET number, VAT details, and bank coordinates to be correctly embedded in the XML data stream — it is not simply a PDF export.
- Does your accounts payable team understand what changes in their supplier invoice processing workflow? Automatic receipt via PA changes the validation chain — a short training session is non-negotiable.
- Are your key subcontractors and suppliers also connected? If your suppliers cannot send electronically, that is their obligation — not yours to accept a PDF workaround in their place.
What to Watch After September 1
The September 1 deadline is not a finish line. Three milestones follow:
- September 1, 2027: the sending obligation extends to SMEs, micro-enterprises, and sole traders
- DGFiP audits: expected from the second half of 2026 — first tax assessments related to e-invoicing non-compliance are likely in early 2027
- E-reporting: the parallel obligation to transmit B2C and international transaction data to the DGFiP runs on the same schedule — an obligation that is frequently overlooked in compliance projects
Organisations that connected their ERP to a PA and tested flows before J-0 are well positioned. Those discovering configuration issues on September 1 face several weeks of remediation — at a time when PAs and ERP integrators have been at full capacity since July 2026.
