1. Confirm that this transaction belongs on the regulated receiving path
Start with scope, not the inbox. Service-Public states that the French reform has applied since 1 September 2026: businesses within scope must be capable of receiving electronic invoices, while large enterprises and ETIs begin issuing and e-reporting from that date; the issuing and e-reporting start for SMEs and micro-enterprises follows in 2027. That timetable means a buyer may already have a regulated receiving obligation even when a smaller supplier is not yet required to issue under the new timetable. Record the supplier’s category and the reason it used the regulated channel, but do not infer delivery merely from the calendar. Verify the actual transaction and both legal entities. The central e-invoicing path concerns domestic B2B supplies between VAT-liable businesses established in France. B2C transactions and international flows are treated differently and may belong in e-reporting rather than this receiving investigation. Confirm the contracting supplier, invoicing supplier, buyer legal entity, establishment concerned, VAT treatment, invoice date and the system in which the purchase was ordered. A shared trading name or group name is not enough: compare the supplier and buyer SIREN, the relevant SIRET where establishment-level routing is used, and any reasoned electronic address carried for the recipient. Then establish what is alleged to exist. Ask whether the supplier created a structured or hybrid electronic invoice and submitted it through a plateforme agréée (PA), rather than merely emailing a PDF or making a portal image available. DGFiP explains that affected businesses use an approved platform to send and receive invoices and required data. A compatible software product cannot perform the regulated PA role by itself unless it is registered as a PA. An email attachment can be useful as a readable continuity copy, but it is not evidence that the regulated invoice travelled through the required route. If the flow is out of scope, move it to the appropriate contractual and tax process; if it is in scope, continue with one trace of the original document.
