The National System of e-Invoices (pl.: KSeF) - what is it?

The National System of e-Invoices (pl.: KSeF) is an IT platform for issuing, receiving and storing invoices in a structured form (XML).

In 2022, a structured invoice will be another form of invoicing, next to paper and electronic invoices.

From the 2nd quarter of 2023, a structured invoice will become the only form of invoicing, and the use of the National e-Invoices System will be obligatory.
