After almost six years of preparation, consultation, technical work and successive changes to the implementation roadmap, the first major deadline has now passed. Yet the developments of recent months, and particularly those seen during the summer of 2026, show that the transition is not as straightforward as initially expected, and will at least keep going until the end of the year.
The implementation timeline in France
The first phase of the French electronic invoicing reform officially entered into force on September 1, 2026, and will be extended progressively:
- September 1, 2026: mandatory e-invoicing reception for all businesses, with e-invoice issuance & e-reporting obligations beginning only for medium and large-sized companies
- September 1, 2027: e-invoice issuance and e-reporting obligations become mandatory for small and businesses and micro-enterprises
Grace period confirmed
The French Government and tax authority have finally introduced flexibility around e-invoicing and e-reporting enforcement by stating that penalties wouldn’t be applied until the end of the year:
- With July 2026 official publication of the “Electronic invoicing: practical guide to getting started by September 1, 2026 [↗︎]”, it has been first announced that automatic penalties will not be applied before January 1, 2027.
- Taking into consideration August 2026 technical and operational readiness, the Minister of Public Action and Accounts further announced, first during a radio news interview and later on August 26th during an official conference and publication [↗︎] that “no sanctions will be applied to any company in 2026”.
A busy summer ahead of the September deadline
The final months before the September deadline were particularly active. The French authorities published several important resources, including the latest decree and ministerial order on e-invoicing & e-reporting, the Schematron rules for F10 flows and a new practical guide to electronic invoicing.
At the same time, the CIBS recodification (recodification of French VAT legislation) was also postponed, avoiding another major change at the time of the reform’s launch. This recodification will impact VAT content and VATEX to be indicated on invoices.
Operationally, the summer also saw a clear acceleration. The pilot expanded to around 30,000 companies, while the number of companies registered in the PPF directory increased significantly to 58% as the September deadline approached.
However, these increasing figures should be put into perspective. Compared with the millions of businesses concerned by the reform, pilot participation and PPF directory onboarding remained relatively limited.
From technical readiness to operational readiness
The French e-invoicing reform is not simply about connecting companies to a new infrastructure. It requires finance, billing and accounting teams to adapt to entirely new processes, including invoice lifecycle statuses (mandatory & optional ones) and the management of both technical and business anomalies.
This distinction between technical and operational readiness is particularly important. While a customer may have selected an Accredited Platform and declared a routing address in the PPF directory, yet still not be operationally ready to receive and process electronic invoices.
Feedback from the pilot has already shown that companies considered technically ready can still encounter significant difficulties under real operating conditions, with companies also stepping back because processes are still lacking.
In the light of the recent context, many French medium & large-sized companies have therefore faced a strategic choice at the end of the summer regarding the implementation of e-invoicing on issuance:
- Approach 1: Activate e-invoicing immediately for every technically ready customer
- Approach 2: Adopt a progressive rollout over the coming months
The second approach has been seen, by many companies, as providing valuable time, to test real transactions and train operational teams on situations that may not have been sufficiently covered during the pilot, including Accredited Platforms or PPF rejections, business anomalies, lifecycle statuses, incorrect SIREN or routing IDs, and other transmission issues.
The approach chosen was mainly motivated regarding the impact of an incorrectly routed or rejected invoice in delayed payment but also considering that a large volumes of unresolved anomalies can quickly create additional workload for operational teams.
Following Government and Tax Authority guidelines stating that companies must ensure business continuity, the period from September to the end of 2026 therefore provides an important opportunity to move progressively towards a full implementation.
