Configuration of Avalara e-invoicing for Belgium, align Avalara and Zuora identifiers and mandates, and ensure compliant PEPPOL invoicing and correction flows.

After setting up your Avalara E-Invoicing and Live Reporting account, generate the API credentials that Zuora uses to connect to Avalara. Then activate your Avalara company profile for Belgium and select the PEPPOL mandate and network required for Belgium e-invoicing flows.

When you configure Belgium in Avalara, make sure that the identifiers and mandate-related values recorded during Avalara onboarding are also aligned with the related Zuora configuration. In Zuora, create the Belgium business region, link it to the Avalara service provider, and populate the required seller information, such as country, legal business details, tax-related identifiers, business address, and contact information.

Because Belgium is a PEPPOL country, ensure that the PEPPOL identifiers and endpoint-related values used in Avalara are consistent with the identifiers used in Zuora business regions and account e-invoicing profiles. This helps prevent validation failures caused by mismatched seller, buyer, or routing information.

For Belgium, the supported billing documents are invoices, credit notes or credit memos, and debit notes or debit memos. Credit notes are the primary correction mechanism. After an invoice is sent through PEPPOL, it cannot be deleted; to nullify or correct it, issue a full or partial credit note that references the original invoice.
