Also called PA, PDP, Plateforme de Dématérialisation Partenaire, approved platform
A Plateforme Agréée is a platform accredited by the French tax authority to issue, transmit and receive electronic invoices on your behalf, and to report the required data. Every business subject to French VAT must be connected to one from 1 September 2026.
These were called Plateformes de Dématérialisation Partenaires, or PDP, throughout the design of the reform. The 2026 Finance Bill replaced the term with Plateforme Agréée across the regulatory documentation.
Both names describe the same thing, and a lot of vendor material still says PDP. If a supplier asks which PDP you use, they are asking which PA you use.
The reform routes invoices through accredited platforms rather than directly between businesses. Your PA is your connection to the network: it sends what you issue, receives what is sent to you, and passes the tax relevant data to the administration.
That makes choosing one a procurement decision with a deadline attached, and it is separate from the question of whether your invoices are valid. A PA moves the file. It does not make a malformed invoice conformant.
A platform routes the invoice. Whether the invoice is conformant is a separate question, and this answers it.
