France’s e-invoicing and e-reporting mandate officially went live on 1 September 2026. After years of preparation, redesign and delay, one of Europe’s most closely watched digital tax reforms has moved from planning into operation.
From this date, every business in scope must be able to receive electronic invoices. Large companies and ETIs must also issue compliant e-invoices and transmit the required transaction and payment data to the French tax authority. SMEs and micro-businesses will join the issuance and e-reporting mandate from September 2027.
The scale of the reform is significant. More than 10 million economic operators are affected, and the French government confirmed on go-live day that 66% of businesses had already selected their approved platform.
But France is not expecting a perfect Day One.
In an announcement accompanying the launch, Minister for Public Action and Accounts David Amiel confirmed that no company will face sanctions during 2026. The message is clear: 1 September marks the start of operational adoption, not the end of the transition.
What changes now?
France’s reform changes much more than invoice format. It introduces a regulated model for how invoices, transaction data and payment information move between businesses, approved platforms and the tax authority.
Under the mandate, companies must be ready to:
- receive structured electronic invoices through the French e-invoicing framework;
- issue compliant e-invoices when their phase of the rollout applies;
- report transaction data for flows that fall outside domestic B2B e-invoicing;
- transmit payment data where required;
- manage invoice lifecycle statuses correctly;
- work with an approved platform connected to the French model.
This makes the French mandate one of the most comprehensive e-invoicing reforms in Europe. It combines domestic B2B e-invoicing with e-reporting, payment data and platform governance. For many organisations, this affects finance, tax, IT, master data, Accounts Payable and Accounts Receivable processes at the same time.

Why the transition period matters
The decision not to apply sanctions during 2026 gives companies room to stabilise their processes. But it should not be read as a reason to delay. The French reform is already live, and the operational work now becomes more concrete.
Companies need to test whether their chosen platform is connected, whether invoice flows work as expected, whether data is complete, and whether internal teams understand how exceptions will be handled.
This is especially important because France has built a platform ecosystem with more than 130 approved private platforms. Selecting a platform is only one part of readiness. Businesses also need to connect it to their ERP, define roles and responsibilities, validate data quality and prepare for lifecycle status management.
We previously covered how businesses should prepare for the September milestone in our article France clarifies how businesses should manage the September e-invoicing go-live. That guidance remains relevant now that the mandate has started.
From deadline discussion to operational reality
In the months before go-live, much of the market discussion focused on whether France would delay the mandate again. The official start confirms that the reform is now moving forward, even with a pragmatic approach to enforcement during the first months.
That shift matters. Companies can no longer treat the mandate as a future compliance project. They now need to understand how it affects day-to-day invoice processing, reporting controls and supplier and customer communication.
Earlier uncertainty around the September deadline was addressed in our previous update on France’s September e-invoicing deadline and delay speculation. With the mandate now live, the focus moves from interpretation to execution.
Platform rules and cybersecurity are becoming central
France’s approved platform model also brings new governance requirements. Cybersecurity is moving rapidly up the agenda. Approved platforms must provide the administration with a cybersecurity progress report by the end of September, report cyber incidents immediately and begin widespread penetration testing this autumn.
Platforms that cannot demonstrate the required security standards could have their operations suspended.
For businesses, this means platform selection and monitoring should not only be based on connectivity or functional coverage. Security, continuity, certification status and operational resilience are now part of e-invoicing compliance.
The importance of platform rules was already clear when France finalised its e-invoicing platform requirements shortly before go-live. You can read more in our earlier article on France’s final platform rules before mandatory go-live.
What this means for AP, AR and tax teams
The French mandate affects both incoming and outgoing invoice flows. Accounts Payable teams need to receive and process structured invoices correctly. Accounts Receivable teams need to issue compliant e-invoices and manage status updates. Tax and finance teams need confidence that reporting data is accurate, complete and submitted on time.
The practical impact is often found in details such as customer and supplier master data, VAT treatment, invoice routing, validation rules, payment information and exception handling. If these elements are not aligned, compliant exchange may still create operational friction.
This is why e-invoicing readiness should be treated as a process and data project, not only as a technical connection.
Key takeaways
- France’s e-invoicing and e-reporting mandate went live on 1 September 2026.
- All businesses in scope must be able to receive e-invoices.
- Large companies and ETIs must also issue e-invoices and report transaction and payment data.
- SMEs and micro-businesses join the issuance and e-reporting mandate from September 2027.
- No sanctions will apply during 2026, but the mandate is active.
- Platform governance and cybersecurity are now critical parts of compliance.
Changes companies need to implement
Companies operating in France should now move from readiness planning to operational control. That means confirming platform connectivity, checking invoice and reporting flows, validating master data, preparing teams for exception handling and monitoring whether lifecycle statuses and payment data are processed correctly.
