Check what defines a structured electronic invoice

National System of e-Invoices

A structured invoice (herein referred to as e-invoice) is an electronic invoice issued through the KSeF system with an assigned identification number. These invoices are saved in an XML format generated in accordance with a logical structure, or a so-called XSD schema. An e-invoice is issued by sending it to the system which verifies its correctness and - after positive verification - assigns it a unique number.

The Minister of Finance informed that a preliminary audit of the National System of e-Invoices exposed that it is not possible to make the system mandatory in 2024 due to critical flaws related to the system's code, functionality and performance.
The minister did not give an exact date when KSeF will be introduced, explaining that the date will be determined after an external audit.

When is it needed?

As announced, all VAT taxpayers with their headquarters or fixed establishments (FEs) for carrying out economic activity in Poland, will be obliged to issue invoices in a structured form.

The process of implementing KSeF is multifaceted. KR Group is distinguished by an individual approach towards each Client, a holistic analysis of your business situation, and a strict focus on understanding the exact needs of your company.
