France's e-invoicing mandate: what it means if you operate there
By Jérôme Denis, AI & data governance consultant · 9 min read · 12 August 2026
France is switching its entire business-to-business invoicing flow onto a mandated electronic rail. If your group has a French subsidiary, a branch, or any entity registered for French VAT, this reaches you whether or not anyone in the head office has been following it. The intent is fiscal: the tax authority wants transaction data close to real time so that VAT returns can eventually be pre-filled. The effect on you is operational, and the first hard date is now weeks away.
Who this actually applies to
The rule attaches to establishment in France, not to nationality of ownership. A German group with a French SAS is in scope for that SAS. A US company with no French establishment, invoicing a French customer from abroad, is not obliged to issue through the French system, but its French customer will have a reporting duty on that purchase. In practice, foreign-owned French entities are affected exactly like domestic ones, and the fact that the parent runs a global ERP does not exempt anybody.
The word used in the French texts is facturation électronique, and it is worth knowing because it does not mean what "electronic invoicing" often means elsewhere. It does not mean emailing a PDF. It means a structured data file exchanged through a platform the tax authority has approved.
The two dates
1 September 2026. Every business subject to French VAT must be able to receive electronic invoices. No exemption for size: sole traders, micro-businesses and craftsmen are all included. From the same date, large companies and mid-caps (entreprises de taille intermédiaire) must issue electronically.
1 September 2027. The obligation to issue extends to small and medium companies and to micro-businesses. After that date, every VAT-registered business in France both sends and receives on the mandated rail.
Anyone who followed this file will know the calendar has moved before. The original plan started in 2023, then July 2024, before the 2024 budget act reset it to September 2026 and 2027. An amendment to push it again to 2027 and 2028 was rejected in April 2025. The current dates are the ones to plan against.
How the system works
Invoices no longer travel directly from supplier to customer. They pass through approved intermediaries, which extract the tax-relevant fields and forward them to the administration while routing the invoice itself to the recipient's platform. The French call the resulting topology the Y model, and it does what you would expect: two branches of commercial flow, one stem of fiscal data.
The intermediary is called a plateforme agréée, PA for short, meaning approved platform. If you are reading older material you will see plateforme de dématérialisation partenaire, or PDP. Same thing. The administration renamed it in July 2025 because "partner" made an official registration sound like a commercial arrangement. Both acronyms are still in circulation, and searching either will find you the current registry.
Three formats are accepted. Factur-X is the practical choice for most companies: a single file that is both a readable PDF and an embedded XML payload, so a human can open it and a machine can parse it. UBL and CII are pure XML, aimed at systems that already speak them. Your platform handles the conversion, which is most of what you pay it for.
The free portal that no longer exists
This is where a lot of published guidance, including French-language guidance, is now wrong, and it changes the budget conversation.
The original design gave the Portail Public de Facturation (PPF), the public invoicing portal, three jobs: national directory, fiscal data concentrator, and a free operational platform where a small business could key in and receive invoices without paying anyone. In October 2024 the tax administration announced by press release that the third job was being dropped. The portal keeps the directory, which maps a company's registration number to the platform it uses, and it keeps the concentrator role feeding data to the authorities. It does not send, receive or archive invoices.
The consequence is direct. There is no free public option. Every French entity, down to the one-person business, must contract with a private approved platform and pay for it. If your French subsidiary's plan was "we will use the government portal", that plan no longer exists and needs replacing before September.
E-reporting, the part foreign groups miss
Alongside invoicing there is a second obligation called e-reporting, and it is the one that catches international operators, because it covers exactly the transactions the invoicing mandate does not.
E-reporting applies to sales to private consumers, and to transactions with parties outside France: exports, imports, intra-EU supplies and acquisitions. If your French entity sells to consumers, or trades with the rest of the group abroad, or buys from a foreign supplier, those flows do not go through the invoicing rail. They still have to be reported periodically, with payment data in some cases. A group that maps only its French domestic B2B flows and declares itself ready has usually missed half its obligation.
Penalties
Failing to issue an invoice in the required electronic form carries a flat 15 euros per invoice, capped at 15,000 euros per calendar year per business. Missing or late e-reporting is 250 euros per omission, under the same annual cap. Neither figure will sink a large group. Both are irritating enough to make the compliance project cheaper than the alternative, which is the point of setting them there.
What to do between now and September
- Choose and contract an approved platform
Check the registry maintained by the tax administration and confirm the platform is actually registered rather than in the process of applying. Ask specifically how it connects to your existing ERP, because a platform that requires manual file upload is a platform that will not be used.
- Clean the customer and supplier master data
This is the step that decides whether September is quiet or loud. Every French business partner needs an accurate SIRET registration number and, where relevant, a valid intra-EU VAT number. An invoice addressed with a wrong or missing SIRET is rejected automatically by the platform. There is no human at the other end who will work out what you meant.
- Map your flows against the two regimes
Separate domestic B2B, which goes on the invoicing rail, from consumer sales and cross-border transactions, which go on e-reporting. Groups with intercompany flows should do this before choosing a platform, because it affects which features you need.
- Run in parallel before you have to
Issue a real batch through the platform while you can still fall back. Rejections in a test run are information. Rejections in October are unpaid invoices.
The realistic difficulty is not technical. It is that the change lands on people who were doing something simple, and the new process is not simple. Budget for training and for a noisy first quarter, and treat any vendor promising a seamless transition with the scepticism it deserves. An operational audit before you commit to a platform tends to cost less than switching platforms afterwards.

FAQ
When does French e-invoicing become mandatory?
Every VAT-registered business in France must be able to receive electronic invoices from 1 September 2026. Large companies and mid-caps must issue them from the same date. Small and medium companies must issue from 1 September 2027.
Does a PDF emailed to a customer count as an electronic invoice?
No. The invoice must be in a structured format such as Factur-X, UBL or CII and must travel through a platform approved by the French tax authority.
Is there still a free government platform?
Not for exchanging invoices. The public portal was scaled back in October 2024 and now serves only as the national directory and the channel that forwards tax data to the authorities. Every business has to contract with a private approved platform.
Does the mandate apply to a foreign company selling into France?
The invoicing mandate covers domestic business-to-business transactions between entities established in France. Cross-border sales and sales to consumers fall under e-reporting instead, which obliges the French-established party to report the transaction data periodically.
What are the penalties?
15 euros per non-compliant invoice, capped at 15,000 euros per calendar year, and 250 euros per missing or late e-reporting submission, also capped at 15,000 euros a year.
