Your VAT / Tax ID is required for Peppol e-invoicing. It identifies your business on the invoice and in the XML file.

Belgian format

For Belgium, use the full number including the country code, for example:

BE0123456789

Validate your VAT number

  1. Open Company Settings.

  2. Enter your VAT number in VAT / Tax ID.

  3. Click Validate.

  4. If validation succeeds, you will see a confirmation message. Save your settings to keep the result.

What you see for Belgian companies

When your company country is set to Belgium, the settings page shows the derived Peppol Endpoint ID and scheme ID based on your VAT number. This helps confirm the app will write the correct seller details in the XML.

Non-EU VAT numbers

If your VAT number is outside the EU, validation may only check the format. Make sure the number is still correct for your business.
