France is not just introducing e Invoicing. It is introducing an ecosystem.

Between supplier and tax authority sits a new layer: the approved platform (PA, originally called PDP).

๐Ÿ”Ž Invoice exchange flows through approved platforms
โžœ validation logic sits outside the ERP

๐Ÿ”Ž Reporting obligations run in parallel
โžœ data consistency becomes critical

๐Ÿ”Ž Multiple actors interact in one process
โžœ coordination becomes part of compliance
