KSeF e-invoicing

Send and receive e-invoices via KSeF and comply with the upcoming Polish e-invoicing mandate by connecting your business to Pagero’s open, cloud-based network.

E-invoicing via KSeF

Poland adopted Peppol for B2G e-invoicing in November 2019. The course is now set for a nationwide obligation for B2B e-invoicing. For this purpose, the National System of e-Invoicing (KSeF – Krajowy System e-Faktur) is currently being created, which is to be mandatory for all taxpayers doing business in Poland.

The mandate to use KSeF has already been postponed several times. On April 26, 2024, the Ministry of Finance announced a new phased timeline for the KSeF implementation.

Important dates

Oct 2021 – Dec 2021

KSeF pilot phase (e-invoices were not valid for tax purposes).

January 2022

Voluntary e-invoicing phase; recipient consent is required (valid for tax purposes).


Starting February 2026, businesses with sales exceeding PLN 200 million (ca. EUR 46 million) must comply with the KSeF. As of April 2026, all entrepreneurs will fall under the scope.

Structured invoices give taxpayers the full benefits of end-to-end process automation.


Mutual settlements and invoice booking are more manageable on the Krajowy System e-Faktur platform.
