From 1 September 2026 every French business must be able to receive a structured electronic invoice. There is no delay — there is a documented tolerance, which is a different thing.
If your group has a French entity or French B2B customers, this is the nearest live obligation on the wall.
Who it binds
- Receiving: all businesses established in France, regardless of size, from 1 September 2026.
- Issuing: large enterprises and mid-size companies (ETI, roughly €250m–€1.5bn turnover) from 1 September 2026. SMEs and micro-enterprises from 1 September 2027.
- A UK group is caught through its French subsidiary or branch, and commercially through French customers who can no longer process a PDF as a compliant invoice.
What it actually demands
- Contract with an accredited platform (PDP / PA). The public PPF platform's role has been narrowed to directory and administrative consolidation — it is not a universal free hub.
- Structured formats: Factur-X, UBL or CII. EDIFACT is permitted between accredited platforms but not for direct PPF transmission, which is exactly where existing UK–French EDI flows break.
- Clean legal-entity and SIRET data, and VAT determination that produces structured tax codes rather than free-text.
DGFiP's July 2026 startup guide sets out an explicit tolerance — no automatic sanctions where difficulties are documented, and invoices sent by email, PDF or paper remain valid at launch. That is a landing ramp, not a postponement, and it is discretionary. The commercial risk is not the penalty. It is a French customer who cannot book your invoice, and a receivable that ages while somebody works out why.
What it means for the estate
Sage X3 2026 R1 (June 2026) shipped e-invoicing for Belgium, France, Germany and Spain — which means the functionality exists and requires 12.0.39. An estate below that patch level cannot ship it, and see the SQL Server 2016 page for why that is rarely a small upgrade.
Treat this as a cash-conversion and control risk rather than a penalty risk, and it becomes a much easier paper to get funded.
