PDP (Plateforme de Dématérialisation Partenaire) is a private e-invoicing platform registered with the French tax authority. Under the French reform (2026–2027), businesses exchange domestic B2B e-invoices through PDPs, which also report data to the administration. When comparing software for France, the key question is whether the vendor is — or connects to — a registered PDP.
