Verify all your suppliers' and customers' e-invoicing capabilities and Peppol status at once by uploading a list.
A Peppol Check verifies whether a company is registered on the Peppol network. Enter a VAT number, KBO/CBE number or company name and our tool searches the Peppol SML/SMP directory. You instantly see whether the company can receive e-invoices over Peppol, which endpoint ID it uses, and which document types it supports.
Since 1 January 2026, e-invoicing over Peppol is mandatory for all Belgian B2B companies. Check whether your customers and suppliers are already registered before you send invoices. Companies that are not on Peppol risk fines of up to €5,000. The Peppol network is international, so you can also look up companies in the Netherlands and across Europe.
