Webinar: Mandatory KSeF 2026 – what do SMEs need to know?

From January 1, 2026, the use of the National e-Invoice System (KSeF) will become mandatory for all entrepreneurs. The implementation of the new system requires companies to prepare both technically and organizationally to ensure the correct issuance, receipt, and archiving of electronic invoices. Therefore, we invite business owners, CFOs, and accounting teams to a free webinar, during which experts will present all the most important aspects of the new obligation and practical tips for SMEs. During the webinar, participants will learn, among other things: • What exactly KSeF is and what benefits it brings to companies. • How to access the system and assign the appropriate permissions. • How to issue and receive invoices in KSeF. • What documents will not be available in the system and what to look out for. • How to correctly mark invoices and avoid scam invoices. • What are the possible sanctions for incorrect use of KSeF. The webinar will be led by: Patrycja Mikuła – tax advisor with many years of experience working for international consulting companies and as a chief accountant in companies with foreign capital.
