BR-FR-21_BT-49: Buyer address on B2B invoices must start with the buyer's SIREN

In short

Fatal: fails the selected checks.

BR-FR-21_BT-49 means a B2B invoice has a buyer electronic address that does not start with the buyer's SIREN, or does not use scheme 0225. Fix it by building the address from the buyer's SIREN and setting its scheme to 0225.

What it means

When the invoice has a BAR note with the value B2B and the document type (BT-3) is not a self-billing type (389, 500, 501, 502, 261, 471 or 473), the buyer's electronic address (BT-49) must start with the buyer's SIREN. The SIREN is the buyer's company registration number (BT-47) given with scheme 0002. The scheme of the address itself (BT-49-1) must be 0225. Self-billed documents and invoices with another or no BAR value are not checked. The CII rule set names the fields with the business terms BT-3, BT-47 and BT-49-1, but it checks the same thing.

Why it matters

The buyer's electronic address is where the approved platform (plateforme agréée) delivers the invoice. On French B2B invoices it must be built from the buyer's SIREN so the buyer can be found, otherwise the invoice is rejected.

How to fix it

Check the buyer's SIREN in the company registration number field (BT-47) and make sure its scheme is 0002. Then set the buyer's electronic address so that it begins with that same SIREN, and choose scheme 0225 for it. In your software this is usually the e-invoicing address on the customer record. If the sale is not between two businesses, the BAR note should not say B2B.

The rule as published

Si le traitement est BAR/B2B et que le type de document (cbc:InvoiceTypeCode) n’est pas en autofacture (389, 501, 500, 471, 473, 261, 502), alors le BT-49 (cbc:EndpointID) doit commencer par le SIREN (cbc:ID[@schemeID='0002']) et le schemeID doit être égal à "0225". Valeurs actuelles : BAR = " … ", EndpointID=" … ", schemeID=" … ", SIREN=" … ".

Where France CTC (CII) run it, the rule reads:

Si le traitement est BAR/B2B et que le type de document (BT-3) n’est pas en autofacture (389, 501, 500, 471, 473, 261, 502), alors le BT-49 (EndpointID) doit commencer par le SIREN (BT-47) et le BT-49-1 (schemeID) doit être égal à "0225". Valeurs actuelles : EndpointID=" … ", schemeID=" … ", SIREN=" … ".
