- Only 5230 companies have voluntarily adopted the National e-Invoice System (KSeF) despite the upcoming mandatory implementation in 9 months.
- Experts warn that companies face potential chaos, lack of a testing environment, tight schedules, and numerous regulatory changes.
- The transition to fully electronic, structured e-invoices is a significant reporting revolution for businesses.
- Since January 2022, only 5230 firms have used KSeF, and the number of electronic invoices sent is low compared to the expected volume.
- There is a crisis of trust in KSeF and legal stability, with some companies doubting the final implementation date of February 1, 2026.
- The absence of a testing environment hinders companies from accelerating their adaptation process.
- A new testing environment is expected to be available by September 30, 2025, which experts consider insufficient time for compliance.
