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.

Enable Chorus Pro on customers

Chorus Pro automatic transmission is only relevant for government-affiliated customers (B2G sales). In order for Hyperline to send invoices via Chorus Pro, you need to enable the Government affiliated flag on the relevant customers. For each customer where Chorus Pro transmission applies, go to the customer details page, click Edit in the Information section, and toggle on the Government affiliated option.
