Chorus Pro service portal allows the transmission and validation of documents relating to the financial execution of works contracts.

The documents as a whole constitute an invoicing file that breaks down as follows :


The monthly invoicing process usually starts with the transmission by the contracting party (supplier) of the draft monthly statement (or works status).

The issuer submits a document in Chorus Pro service portal. The following party receives it and then associates its own document.

Notifications that enable progress of the invoicing file to be tracked are sent regularly.

Each party has the opportunity to make an initial submission event of absence of one of the processing parties.

  • Existence of private and public structures in Chorus Pro service portal.
  • Creation and activation of a user account.
  • Authorization for users to access the "Work invoices" application.
  • Definition of a process for managing invoicing documents between parties.
