What is KSEF, and why does it matter to you?
KSeF (Krajowy System e-Faktur) is Poland's centralised national e-invoicing platform, operated by the Ministry of Finance. From 2026, it is mandatory for all VAT-registered businesses in Poland to issue and receive structured invoices exclusively through KSeF.
Non-compliance means invoices won't be legally valid, directly impacting cash flow and VAT deductions.
