Chorus pro

Chorus Pro portal mandatory for public sector invoices


Since January 2017, the French government has required public sector actors (State, local authorities, hospitals, public institutions) and their suppliers to use e-invoicing. A specific portal has been set up for this : Chorus Pro.
Tenor supports public sector suppliers with its eDemat software, a dematerialization solution for incoming and outgoing invoices that can automatically send invoices to Chorus Pro via EDI flows.
