September 2026 is not a distant deadline anymore. For businesses established or VAT-registered in France, mandatory e-Invoicing is arriving in weeks, not months. And for many businesses, the gap between where they are today and where they need to be is wider than they realise.
This blog sets out what the French mandate requires, what it means operationally for your business, and how to close that gap before the deadline arrives.
France’s reform introduces two interconnected obligations that apply simultaneously. The first is mandatory e-Invoicing for domestic B2B transactions, meaning invoices must be issued and received in a structured electronic format rather than as PDFs or paper documents. The second is e-reporting, which requires transaction data for B2C sales and cross-border transactions to be transmitted to the French tax administration, the Direction Générale des Finances Publiques (DGFiP), even where the invoice itself does not go through the e-Invoicing framework.
Together, these two obligations give the DGFiP near real-time visibility over a business’s transactional activity in France. The mandate is not primarily about convenience or efficiency, though those benefits exist. It is about giving the French tax authority a continuous feed of invoice-level data.
For businesses, this means invoicing is no longer purely an accounts receivable and accounts payable process. It is now a compliance-critical workflow with direct tax implications at the point of transaction.
The French framework operates through approved platforms known as Plateformes Agréées (PAs). These are certified intermediaries that connect businesses to each other and to the DGFiP’s central platform, the Portail Public de Facturation (PPF). Invoices flow through a PA, which validates the data, routes it to the recipient, and simultaneously transmits the required information to the tax administration.
Approved invoice formats under the French mandate include Factur-X, UBL 2.1, and CII. A standard PDF invoice, even one sent by email, will not meet the requirements once the mandate takes effect.
The implementation timeline is as follows:
The receiving obligation on 1 September 2026 applies to every business regardless of size. That date is now weeks away. Any business that has not yet connected to a PA or confirmed its receiving capability is already behind.
For a comprehensive breakdown of the French e-Invoicing framework, including format requirements, platform obligations, and the latest DGFiP guidance, we have just launched a dedicated France e-Invoicing country guide covering everything businesses need to know. If you are navigating this mandate, it is the most complete resource we have produced on the subject and it is free to access.
This is where VAT IT is different from most providers talking about the French mandate.
To transmit invoices and e-reporting data within the French framework, a platform must be officially accredited by the French government as a Plateforme Agréée. This is not a self-certification, a partnership arrangement, or a pending application. It is a formal accreditation issued by the French authorities.
eezi by VAT IT holds that accreditation.
That means businesses connecting through eezi are operating within a government-certified framework from day one. Not all providers can say that. For businesses evaluating their options right now, it is a distinction worth paying attention to. Working with an accredited PA removes the compliance risk of connecting through a provider that has not yet received formal approval, and it means that as the DGFiP continues to refine technical requirements, eezi’s accreditation reflects ongoing compliance with those standards.
For businesses with a September deadline, choosing a platform that is already approved is not a nice-to-have. It is the baseline.
Businesses that have started preparing for the French mandate often discover that the technical integration is only part of the challenge.
The more demanding work tends to involve data quality. The French framework requires specific data fields to be correctly populated on every invoice, including buyer and seller identifiers, VAT numbers, invoice classification codes, and payment terms. Where master data in ERP or billing systems is incomplete or inconsistent, invoices will fail validation at the PA level before they ever reach the recipient.
There is also the question of supplier onboarding. Receiving compliant e-invoices from suppliers requires those suppliers to be issuing through accredited platforms themselves. Businesses with large supplier bases may need to communicate the requirements to suppliers and confirm their readiness before September.
Finally, there is the e-reporting obligation for B2C and cross-border transactions. This is a separate data feed to the DGFiP that runs alongside the e-Invoicing framework. Businesses that focus entirely on the B2B invoicing requirement and overlook e-reporting will find themselves only partially compliant.
If your business operates in France but is not established there, the e-reporting obligations under the French mandate create an additional layer of complexity that many businesses are not yet across.

With September approaching, the window for preparation is narrowing. Businesses that have not yet started should focus on four immediate priorities:
Confirm your receiving capability
The obligation to receive compliant e-invoices applies to all businesses from 1 September 2026. Connecting to an accredited PA and confirming your receiving setup is the minimum requirement that applies universally, and the clock is running.
Assess your ERP and billing system readiness
Can your systems generate invoices in Factur-X, UBL 2.1, or CII format? If not, what is required to enable that capability? This is a question that needs an honest answer before the deadline, not after.
Review your invoice data quality
Run a review of the mandatory data fields required under the French framework against your current invoice templates. Identify gaps and correct them before live submission begins.
Understand your e-reporting obligations
If your business has B2C sales or cross-border transactions in France, make sure your e-reporting process is mapped and ready to run alongside the e-Invoicing framework.
1. Does the mandate apply to foreign businesses with a French VAT registration?
Yes. The obligation attaches to the French VAT registration, not the country of establishment. A business registered outside France but holding a French VAT number is within scope and must be able to receive compliant e-invoices from 1 September 2026, with issuing obligations following according to company size.
2. What happens if a business continues issuing PDF invoices after the mandate takes effect?
PDF invoices will not meet the French e-Invoicing requirements once the mandate applies. Invoices issued outside the approved platform framework will not be treated as legally valid documents for VAT purposes, which creates both compliance risk and potential issues with payment and VAT recovery for both parties.
3. What is Factur-X and why does it matter?
Factur-X is a hybrid invoice format that combines a human-readable PDF with an embedded structured XML data file. It is one of the approved formats under the French mandate and is particularly relevant for businesses transitioning from PDF-based invoicing, as it retains the familiar visual format while meeting the structured data requirements of the framework.
4. How does e-reporting differ from e-Invoicing under the French mandate?
e-Invoicing covers the structured exchange of invoices between business customers and suppliers for domestic B2B transactions. e-reporting covers the transmission of transaction data to the DGFiP for B2C sales, cross-border supplies, and payments. Both obligations apply from September 2026 and both require connection to an approved platform or direct API integration with the PPF.
