Structured Electronic Invoicing

Starting January 1st, 2026, all Belgian VAT-liable companies will be required to exchange structured electronic invoices via the Peppol network. These invoices will be sent directly between software systems and will be the only legally compliant documents from that date onward. If your company is ready to send invoices via the Peppol network, please read the tips below carefully. Is your company VAT-liable but not yet registered on the Peppol network? Then contact your accounting software provider as soon as possible and ensure your company is ready in time.

TIPS for correct invoicing via Peppol:

• Don’t forget to link the SPIE purchase order number (Purchase Order nr) to the PEPPOL field during setup. Our PO have the following structure: XXXX/XXXXXXX ABC/DEF.

Invoices without a PO will not be processed.

• It is important that each invoice corresponds to one purchase order (and its attachments).You can send several invoice for one Purchase Order, but only mention one PO on theinvoice.

• SPIE Peppol ID: 0208:0434499028
