France has published the final implementing rules for its mandatory B2B e-invoicing framework, just one month before the first phase of the mandate takes effect. While the implementation timeline remains unchanged, the legislation provides additional clarity on how approved platforms must operate and what businesses should expect as they prepare for 1 September 2026.
On 28 July 2026, the French Official Journal published Decree No. 2026-677 together with the Order of 27 July 2026. Both measures implement provisions introduced through the 2026 Finance Law and complete another important milestone in France’s transition to mandatory e-invoicing.
The publication follows a series of regulatory and technical updates released throughout recent months. France has already confirmed that the 1 September 2026 implementation date remains unchanged, published expanded AFNOR technical specifications, clarified how organisations should prepare for go-live, and announced a pragmatic enforcement approach during the initial implementation period. Together, these developments complete much of the legal, technical and operational framework organisations should now be working towards.
What has changed?
The new implementing order does not introduce new compliance deadlines. Instead, it further defines how the French e-invoicing ecosystem will operate in practice.
One of the most important updates concerns the governance of approved platforms. The legislation introduces strengthened security obligations, including ISO/IEC 27001 certification, ongoing surveillance audits and the requirement for platforms to demonstrate continued compliance after approval.
The order also provides greater detail on interoperability. Approved platforms must be capable of exchanging invoice data consistently with:
- the national central directory;
- the French tax administration;
- other approved platforms participating in the network.
These requirements reinforce the interoperability model underpinning the French framework, ensuring businesses can exchange invoices regardless of which approved platform they use.
More clarity for businesses
The legislation also defines the contractual relationship between taxpayers and their chosen approved platform in greater detail. It specifies which information must be captured, maintained and exchanged for electronic invoice reception.
Although much of this responsibility sits with approved platform providers, organisations should understand these requirements before finalising their implementation. Selecting a provider is no longer just a technical decision. Businesses should also assess security, operational maturity and long-term compliance capabilities.

The implementation timeline remains unchanged
The publication once again confirms that France’s implementation schedule remains on track.
From 1 September 2026, large enterprises and intermediate-sized businesses must issue and receive electronic invoices under the new framework. Small and micro businesses will become subject to mandatory electronic invoice issuance from September 2027, while all businesses must be capable of receiving electronic invoices from September 2026.
With only weeks remaining before the first phase begins, the focus is no longer on new legislation but on operational readiness. Organisations should have selected their approved platform, completed ERP integrations and validated their invoice processes before mandatory exchanges begin.
What businesses should do now
The legal framework is now largely complete. The remaining priority is implementation.
Finance and IT teams should ensure that:
- their approved platform has completed all required certification and onboarding activities;
- ERP and finance systems are ready to exchange compliant electronic invoices;
- business processes have been tested for sending, receiving and handling invoice exceptions;
- users understand the operational changes introduced by the new framework.
Businesses that have not yet completed their preparations should use the remaining weeks before 1 September as their final implementation window rather than additional planning time.

France continues to refine its e-invoicing framework as implementation approaches. At the same time, countries across Europe are introducing similar reforms as part of their own digital tax strategies and the wider ViDA initiative.
