§09FAQ

Common questions about Belgian e-invoicing.

Is there a free plan, and what are the limits?

Yes, free forever — 10 TVA/BTW invoices per month, 1 user, 1 organisation. Full compliance, PDF generation, and INTERVAT XML export included. No credit card required.

TVA vs BTW — are those the same thing?

Yes. TVA is the French term (Taxe sur la Valeur Ajoutee) and BTW is the Dutch term (Belasting over de Toegevoegde Waarde). Belgium is bilingual so both appear on the same invoice. Oris prints both abbreviations automatically.

How does the Belgian e-invoicing mandate in 2026 work?

From 1 January 2026, all VAT-registered Belgian businesses exchanging B2B invoices domestically must use a structured electronic format (EN16931/UBL 2.1) delivered via Peppol. Oris already generates the correct format and routes via BIS 3.0 — no platform switch needed.

Where is my data stored?

Primary infrastructure is in AWS eu-west-1 (Ireland), with Belgium-specific residency available on the Pro plan. Every tenant is isolated via PostgreSQL row-level security; bank details are encrypted at rest with AES-256-GCM.

Which Belgian public holidays does InvoiceChaser skip?

All 10 national feestdagen (Nationale Feestdag 21 Juli, Allerheiligen, Kerstmis, Nieuwjaar, Pasen, Pinkstermaandag, Hemelvaart, Armistice, Dag van de Arbeid, Maria Tenhemelopneming) plus Flemish, Walloon, and Brussels community holidays.

How do I migrate from Exact Online?

Export your customers, products, and open invoices from Exact as CSV. Our bulk importer validates the file in the browser, maps columns, and imports in minutes. Peppol configuration carries over automatically once your BTW-nummer is verified.
