Petre, Adrian: Peppol check
Can I e-invoice this customer? See whether a customer receives e-invoices via Peppol and under which Peppol ID your invoicing software finds them. For one customer, or your whole customer list at once.
Since 1 January 2026, Belgian VAT-registered businesses invoice each other with structured electronic invoices, over the Peppol network. Who must e-invoice? (FPS Finance)
One customer
Every day we read the Peppol Directory, the public register of who receives Peppol documents. A card there is voluntary: a company not in it may still be reachable.
This company was in the Peppol register but left it on 1 October 2026. Ask the customer which channel they now receive invoices on.
If the customer is not ready yet, you may send the invoice another way, for example as a PDF; if electronically, with their agreement on a secure alternative. That invoice is valid; the customer risks a penalty. Source: FPS Finance, B2B questions
