Reference details on invoices | E-Invoicing

So that invoices sent to the Bouygues Energies & Services InTec can be processed quickly, certain reference details must be provided on invoices. You can see which details here.

The following invoice reference details must be included:

  • Buyer: Buyer's given name and family name
  • Reference: Project number (11 or 16 digits) OR cost centre code (4 digits)

All invoices must quote the required reference details, no matter whether they are submitted physically (on paper) or electronically. This is because all invoices are processed centrally and distributed to staff electronically for sign-off. Incomplete invoices have to be returned to the sender.
