Frequently asked questions
Who is required to use Chorus Pro for invoicing?
Since January 2020, all suppliers issuing invoices to French public entities—regardless of their size or location—are required to use Chorus Pro. This includes microenterprises, SMEs, and large companies when billing ministries, local authorities, hospitals, and other public sector bodies.
Can foreign suppliers use Chorus Pro?
Yes. Foreign suppliers providing goods or services to the French public sector must also use Chorus Pro. Registration is open to non-resident entities, and the platform provides dedicated onboarding assistance to facilitate cross-border compliance.
Is registration on Chorus Pro mandatory?
Yes. In order to submit invoices and access services such as tracking and communication with public entities, suppliers must first register and create an account on the Chorus Pro platform. The process is free and can be completed online.
What invoice formats are accepted on Chorus Pro?
Chorus Pro supports structured invoice formats including UBL 2.1, CII (Cross Industry Invoice) and Factur-X. Invoices must comply with required fields defined by the French administration to ensure validation and processing.
Are invoices submitted through Chorus Pro legally valid without a digital signature?
Yes. Digital signatures are not required when using Chorus Pro, as the platform itself ensures the integrity and authenticity of transmitted data. This simplifies the process while still meeting legal and fiscal requirements.
Can invoices be tracked after submission?
Absolutely. Chorus Pro provides real-time tracking of invoice status, from submission to payment. Suppliers receive updates at each stage and can communicate directly with public entities through the platform’s built-in messaging system.
Managing public sector invoicing with full compliance
The mandatory use of Chorus Pro for B2G transactions represents a fundamental requirement for all companies supplying the French public sector. Since 2020, businesses must submit all invoices to government entities, local authorities, and public institutions through this centralized portal using structured formats like UBL or Factur-X. This means that ERP systems must be capable of generating, validating, and transmitting compliant invoice data, while also being able to synchronize the document’s lifecycle statuses back from the portal in a fully automated and secure way.
At Code10, we support this transition through a combination of SAP Standard implementation and advance eCompliance integration delivered via our eCompliance Hub. Our solutions support structured invoice generation, validation, and secure transmission, while also ensuring accurate status tracking—helping organizations meet B2G requirements with reliability and control.
