1. Review fitness after the first live flows—not registration alone
France’s reform is now live, so this review should begin as soon as a representative set of genuine invoices has crossed the production chain. Service-Public reported on 2 September 2026 that the reform took effect on 1 September 2026: affected businesses must be able to receive electronic invoices, while large enterprises and ETIs also begin issuing and e-reporting from that date. SMEs and micro-enterprises begin issuing and e-reporting on 1 September 2027. The same official update advises businesses to map flows, adapt procedures and choose a plateforme agréée (PA) suited to their needs. A review is therefore not an abstract software exercise; it asks whether the live operating arrangement fits the company’s obligations, systems and trading patterns. DGFiP explains that affected businesses use an approved platform to transmit and receive electronic invoices and send the required invoice, transaction and payment data. A PA may also convert a supplier invoice into a format suitable for its client while maintaining integrity, authenticity, readability and completeness. Only a registered PA can perform all regulated transmission, reception and reporting functions; a compatible solution still needs a PA for those functions. Confirm the provider’s current status on DGFiP’s official PA list, but do not confuse that status with proof that the service works well for your particular entities, addresses, formats, integrations, volumes or support model. Registration answers an essential regulatory eligibility question. Buyer fitness is a separate evidence question. It includes correct annuaire routing, reliable Factur-X, UBL or CII handling, usable lifecycle information, PA-to-ERP reconciliation, appropriate e-reporting where applicable, support ownership and sustainable manual effort. Start with a day-7 baseline once seven calendar days of live use are actually available, then use a rolling 30-day view as evidence accumulates. On 6 September 2026, a business that started on 1 September has not yet completed either window; it can prepare the controls and record observations without presenting an incomplete period as a finished result. This is an internal operational review, not a statutory audit or an official platform score.
