Each company must make their own decisions about how they meet their tax obligations.
Belgium introduced mandatory B2B e-invoicing on 1 January 2026. All VAT-registered companies established in Belgium must now issue and receive structured electronic invoices for domestic B2B transactions. The required format is Peppol BIS Billing 3.0 (UBL 2.1), transmitted via the Peppol network — Belgium's chosen four-corner model for secure invoice exchange.
The obligation applies to all Belgian VAT-registered businesses regardless of size or sector, with no phased rollout by company size. Invoices must be issued within 15 days of the end of the month in which the supply took place. Non-compliance can result in penalties of up to €5,000 per infringement.
Rydoo is actively working on e-invoicing compliance and assesses each company's situation individually, as integration flows and requirements differ by country and business context. If you have questions about how Belgium's e-invoicing mandate affects your setup with Rydoo, reach out to your Rydoo point of contact for guidance tailored to your situation.
