Everything You Need to Know About Mandatory E-Invoicing with Peppol and Odoo 

1. What is mandatory e-invoicing?

Starting from January 1, 2026, mandatory e-invoicing will be enforced for all VAT-liable businesses in Belgium. This means that paper invoices and PDF invoices without structured data will no longer be allowed. All electronic invoices must be exchanged via the Peppol standard, an international standard that enables secure and efficient e-invoicing.

2. What is Peppol?

Peppol stands for Pan-European Public Procurement OnLine. It is a global network for the secure exchange of electronic documents such as e-invoices. By using the Peppol standard, businesses can easily and legally share and process invoices.

3. How does Odoo support e-invoicing?

From Odoo version 17, a free Peppol access point is included as standard. This means you can work fully compliant without extra costs or complex integrations. Odoo simplifies e-invoicing by fully integrating it into your business processes.

7. Are there any downsides to e-invoicing, and how does Odoo help?

Although e-invoicing offers many advantages, there are some challenges:

  • Setup time: Transitioning to Peppol and e-invoicing can take time. With Odoo version 17 or 18, this process is significantly simplified. For older versions, Dynapps provides an integration to ensure compliance.
  • KBO number required: To send an e-invoice, the recipient’s KBO number (Belgian business registration number) is mandatory. Odoo automates this process to prevent errors.
  • Costs for new software: If you don’t yet use Odoo, there may be initial costs. Fortunately, the government offers tax benefits, such as:
    • 20% investment deduction for digital solutions starting in 2025.
    • 120% deduction for renting software or consulting services.
