What is FA_VAT?
FA_VAT (FA(3)) is the Polish format for structured invoices in the national KSeF system (Krajowy System e-Faktur). Its use becomes mandatory for all businesses in Poland in stages from 2026.
How to create FA_VAT invoices

Every input is checked against the EN 16931 and format rules; errors are reported right at the field.
