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—regardless of 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.

​
Setup

Before setting up the integration, you need a Chorus Pro technical account.
1

Log into your Chorus Pro account

2

Navigate to API settings

  • Go to Domains > Connections in the main menu (Domaines > Raccordements in French)
  • Go to the Technical Account section (Compte technique in French)
3

Set up the technical account credentials

  • Set the type of request to Creation of a technical account (Création d’un compte technique in French)
  • Select your company in the company field
  • This creates a login and password — copy these credentials as you’ll need them when setting up Chorus Pro in Hyperline.
4

Enable Chorus Pro integration in Hyperline

  • Ensure you have entered your VAT number and Registration number (SIRET in France) on your invoicing entity.
  • In Settings > Invoicing:
    • Enable Chorus Pro — this option is only available for French invoicing entities.
    • Click the Add credentials button and enter your technical account credentials in the Supplier portal that opens. Once logged in, you can safely close the portal.

​
Testing

To test in sandbox mode, create an account in the Chorus Pro sandbox. Download the CSV file with test accounts and use one of them to log in. For more information, visit the Chorus Pro documentation.

​
Enable Chorus Pro on customers

Chorus Pro automatic transmission is only relevant for government-affiliated customers (B2G sales). 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.

​
Routing

By default, invoices are routed to the customer using their registration number (SIRET), which identifies the public institution. On the customer details page, click the Edit button in the Information section and set the value in the Registration number field. Invoices for customers with a missing registration number will not be automatically transmitted via Chorus Pro.

​
Service code

For some public institutions, an additional service code is required to route the invoice. This code identifies the service within the public institution. If the service code is not provided, the invoice may be rejected during transmission. To set the service code for a specific customer, on the customer details page, click the Edit button in the Information section and scroll down to the E-invoicing code field, where you can enter the service code.
