What is Chorus Pro and when is it required?
Effective: 2020-01-01 · Authority: AIFE (Agence pour l'Informatique Financiere de l'Etat)
Chorus Pro is the mandatory French platform for B2G (business-to-government) e-invoicing to all public sector entities. It has been mandatory for large enterprises since January 2017, mid-sized enterprises since January 2018, and all businesses since January 2020. Chorus Pro accepts Factur-X, UBL, and EDI formats.
How does Chorus Pro relate to the 2026 French B2B mandate?
Chorus Pro covers B2G invoicing (business to public sector) which has been mandatory since 2017-2020. The 2026 mandate covers B2B invoicing (business to private sector businesses). The two systems are separate. Businesses invoicing both public and private sector clients need both Chorus Pro connectivity and PDP/PPF connectivity.
Frequently Asked Questions
- What happens if a supplier does not use Chorus Pro for public sector invoices?
- Public sector entities in France are required to reject non-Chorus Pro invoices submitted through other channels. Suppliers not using Chorus Pro risk payment delays and invoice rejection. The obligation has been in force for all suppliers since January 2020.
- Does Chorus Pro replace a PDP for the 2026 mandate?
- No. Chorus Pro is specific to B2G invoicing. The 2026 mandate requires B2B e-invoicing through a PDP or the PPF. These are separate platforms serving different invoice flows. A business must use both if it invoices both public authorities and private companies.
