Best invoicing software for self-employed

An honest comparison of Belgian invoicing tools for freelancers and independents. Ranked by Peppol support, price, AI features, and readiness for the 2026 mandate.

Criteria

What to look for in invoicing software

With the Belgian e-invoicing mandate taking effect from January 2026, every self-employed person and SME needs invoicing software that is Peppol-native, compliant, and priced for independent workers. We compared the main options honestly. Here is what matters: Peppol connectivity (mandatory from 2026), AI-assisted extraction to save time, Belgian compliance (BCE number lookup, legal template), and transparent pricing.

Peppol-native

Must connect to the Peppol network natively, not as a paid add-on. From January 2026, Belgian B2B invoices must be sent via Peppol.

Price for independents

Freelancers invoice 10-50 clients a month. You should not pay enterprise prices. Look for a flat monthly fee under €20/month.

AI extraction

The best tools extract supplier invoice data automatically so you can process incoming documents in seconds, not minutes.

Belgian compliance

BCE company lookup, correct legal invoice templates, VAT handling for the Belgian market, and 10-year document storage.
