What is Chorus Pro

Chorus Pro is the official digital portal managed by the French public sector (AIFE), used to manage electronic invoicing with government entities in France. As of Today, it allows automatic transmission of invoices to public administrations (G2G/B2G sales). Since early 2020, all companies operating in France—no matter their size—are required to submit invoices to public bodies (ministries, local authorities, hospitals, etc.) via Chorus Pro.
With the upcoming French e-invoicing reforms (2026-2027), Chorus Pro will become part of a broader ‘Portail public de facturation’ (PPF), handling e-invoices between companies and public administrations.
