Chorus Pro B2G Invoice

In this example, we’re issuing a Chorus Pro invoice for business-to-government transactions in France. Chorus Pro is the mandatory platform for submitting invoices to French public sector entities.Notice:

the minimal version (chorus-pro-b2g.min.mdx) contains only the essential fields required to create the B2G invoice,
the fr-chorus-pro-v1 addon ensures the document will be validated using the Chorus Pro rules built into the GOBL library,
the customer must be a French public sector entity with a valid SIRET number,
specific Chorus Pro extensions and identifiers are required for public procurement (such as service codes and commitment numbers),
there are no totals or calculations in the minimal version; all these will be calculated automatically when running gobl build,
the built version (chorus-pro-b2g.mdx) shows the normalized document with calculated totals, line item sums, TVA breakdowns, and automatically generated fields,
the invoice will be formatted according to Chorus Pro requirements and submitted through the platform, and,
all invoices to French public entities above €25,000 must be submitted through Chorus Pro.
