At a glance

What this means for you

KSeF structured invoicing is mandatory from 1 February 2026 for large taxpayers (turnover over 200M PLN) and from 1 April 2026 for everyone else. KSeF is a clearance model, not Peppol.

How FreeBillGen helps

FreeBillGen already generates the structured e-invoice formats most mandates require - Factur-X (EN 16931), Peppol BIS 3.0 UBL, and country formats - from the invoice you create. Export is always free, and direct transmission to networks like Peppol is on the way.
