Hello,

For the Belgian localization it will be mandatory to send sales invoices via PEPPOL as from 01/01/2026. We are working on an implementation where we have set up intercompany, and this is necessary for processing the dimensions.

The following issue arises:

• posting a sales invoice from the source company will create a purchase invoice in the destination company.
• it will also send an e-document to the same company.
• This e-document could be converted into a purchase invoice, but this invoice will already exist. It should therefore be possible to link the PEPPOL message to the created purchase invoice in order to demonstrate that the invoice has indeed been sent via PEPPOL.
