  2. Choose a compatible software: Use invoicing software that natively supports the Peppol format. This will save you many intermediate steps and ensure a smooth and compliant conversion.
  3. Take advantage of the obligation in Belgium: With the electronic invoicing obligation in Belgium, now is the ideal time to adopt software that natively handles the generation of electronic Peppol invoices. This not only simplifies the process but also ensures legal compliance.
