Chorus Pro is the official electronic platform, managed by AIFE (Agence pour l'Informatique Financière de l'État), dedicated to the dematerialized transmission of electronic invoices for the public sector in France. Electronic invoicing via Chorus Pro is part of the strict regulatory framework for public procurement.
Since 2017, the legal obligation applies to all structures, including public institutions, which must use Chorus Pro for transmitting their invoices. The widespread adoption of electronic invoicing also depends on the size of companies and structures involved, with a progressive obligation based on their importance.
With over 1.5 billion invoices processed, Chorus Pro remains the reference for dematerialization and regulatory compliance, in anticipation of the 2026 electronic invoicing reform.
