What Is KSeF Training And Why Is It Worth Participating?
The KSeF training is an initiative of the tax administration. Its purpose is to provide practical support to entrepreneurs who prepare for the mandatory use of the National e-Invoicing System. Participation in KSeF training:
- enables you to learn about the legal basis of KSeF and the deadlines for implementation,
- allows you to test the application and other tools offered by the Ministry of Finance,
- explains the differences between a traditional invoice and a structured invoice,
- allows asking questions to experts from the National Tax Administration.
The free KSeF training is crucial for micro-entrepreneurs and sole proprietors, who often do not use advanced financial-accounting systems. They may need a practical step-by-step guide.

What Elements Should a Good KSeF Training Include?
Not every training offers the same substantive level. Good National e-Invoicing System (KSeF) training should include:
- discussion of the legal basis and deadlines for the implementation of KSeF,
- step-by-step instructions for registering in the system,
- practical exercises in issuing and receiving invoices,
- explanation of the role of tokens and certificates
- discussion of practical problems – e.g. what to do with attachments, how offline mode works,
- space for questions and individual consultations.
National e-Invoicing System (KSeF) Training And the Role Of an Accounting Office
Many entrepreneurs expect accounting offices to handle KSeF implementation. Meanwhile:
- the accounting office does not participate in sales and purchase processes,
- the responsibility for issuing invoices and their compliance with the regulations remains with the entrepreneur,
- the role of the accounting office is to provide substantive support, not to implement the system in the company.
That is why the KSeF training is addressed not only to accountants, but to entrepreneurs themselves.
