As part of the European digitalization initiative, Peppol e-invoicing will become mandatory as of January 1, 2026.
However, this obligation does not apply to everyone. Depending on your situation, one of the following scenarios will apply:
You invoice from outside Belgium and do not use a Belgian VAT number
• The Peppol obligation does not apply to you.
• Your current invoicing process remains valid.
You work through Staffing MS
• Nothing changes.
• You can continue to use your existing invoicing process.
You invoice from a Belgian company to another Belgian company with both a Belgian VAT number
• You must send your invoices via the Peppol network starting from 1 January 2026.
• Please ensure that you prepare your invoicing tools accordingly.
