Belgium E-Invoice 2026

BE E-Invoice Readiness helps Belgian SMEs and accountants organize a private preparation checklist for the 2026 B2B structured e-invoice obligation. Track entities, note workflow gaps, collect questions for accountants and software vendors, review EN 16931 field concepts, and export a dated plain-text readiness packet. The app works offline with local storage only. It does not send invoices, validate VAT numbers, connect to Peppol access points or accounting systems, file VAT returns, or give tax, legal, accounting, or VAT advice. Source rows show publisher links and verification dates so you can re-check official guidance with your adviser. BE E-Invoice Readiness is independent and is not affiliated with the Belgian government, FPS Finance, the European Commission, or any Peppol authority.
