In short
The best invoicing program in Belgium depends on your needs. All serious tools support Peppol in 2026. If you're primarily looking for an accounting package, consider Odoo or Exact Online. For freelancers with a side job, Accountable and Billit are popular. If you work with quotes, briefings, and client hours—like creative agencies and freelancers—Offacto is a strong choice.
Since Peppol became mandatory, many entrepreneurs are looking for a new invoicing program. The market is vast, and websites all promise the same. That’s why we compare the most well-known tools based on what truly matters. Full transparency: Offacto is our own tool. We aim to be honest about where other tools might fit better.
What to look for in an invoicing program?
- Peppol: send and receive without extra costs or a separate module.
- Quotes: can you create quotes that turn into invoices with one click?
- Incoming invoices: are purchase invoices automatically read?
- Integration with your accountant: export or direct connection.
- Payments: QR codes, online payments, and automatic reminders.
- Pricing as you grow: what does it cost if you have more invoices, users, or brands?
