KSeF - it is high time to prepare!
April 2, 2025 at 14:00 CET
The implementation of KSeF is a major challenge, but also an opportunity to bring order and innovation to companies. The process itself, depending on the size of the organisation, can take from a few to even up to several months.
The KSeF is not a project that will be implemented by the IT department alone – it is a challenge for many departments within companies with particular support and structuring of legal and tax processes.
As early as February 2026, the National e-Invoicing System (KSeF) will become mandatory for large companies and 2 months later for others.
