On January 28, 2026, Joanna Koziollek conducted an in-person training session, “National e-Invoice System for Entrepreneurs,” at the Wrocław Center for Technology Transfer of the Wrocław University of Science and Technology.

We would like to thank the participants for their numerous attendance, their substantive questions, and, above all, for sharing their experiences. Your commitment demonstrated that the KSeF is a challenge, but also an opportunity to streamline invoicing processes.

We also extend our sincere thanks to the organizers: the Wrocław Center for Technology Transfer of the Wrocław University of Science and Technology (WCTT), the Enterprise Europe Network, the Horizontal Contact Point, and the Bar Association of Attorneys-at-Law in Wrocław – for their trust, professional organization, and creating a space for substantive discussion.

We invite those of you who were unable to join us in person, as well as all participants of yesterday’s training, to a repeat of the “National e-Invoice System for Entrepreneurs” training session, this time online.
