KSeF Checklist – check your company’s readiness for the system rollout

As of 1 February 2026, companies conducting business in Poland must be prepared for significant changes concerning obigatory e-invoicing. New requirements apply not only to entities established in Poland, but also to foreign companies that have a fixed establishment in Poland.

Preparing an organization for the use of the National e-Invoicing System (KSeF) in Poland is a complex process that goes far beyond the implementation of an IT tool. It also involves tax, process, organisational and, in some cases, competency-related changes. Proper planning and thorough testing across these areas is crucial to ensure a secure and smooth transition to the new invoicing model.

“The KSeF Checklist – Key Control Points Ahead of System Go-Live” is an educational material we have prepared to support you in identifying the key issues that should be addressed before the mandatory use of KSeF in Poland begins. Its purpose is to help structure preparatory activities, highlight potential gaps, and identify areas requiring further analysis. The checklist may be used both prior to the launch of KSeF and after it goes live – as a control tool and an element of ongoing oversight of the invoicing process.

Please note that the relevance and importance of individual checklist items may vary depending on the industry, scale of operations and the specific processes of a given organisation. In certain cases, the checklist may need to be expanded; however, its primary objective is to draw attention to the most critical areas that should be reviewed in connection with the introduction of mandatory KSeF.

We encourage you to contact us should any questions arise regarding the interpretation of individual points or whether a given requirement is in fact met by your organisation. We will be pleased to support you in analysing these areas and planning next steps, so that you can have a genuine level of confidence that your organisation is well prepared to operate under KSeF.
