- Increasing reports of “disappearing invoices” in the National e-Invoice System (KSeF): sellers receive official confirmation, but buyers cannot see the invoices.
- Buyers are unaware of pending invoices, leading to unpaid goods or services.
- Both sellers and buyers may face consequences due to these system errors.
- The issue may persist even after KSeF becomes mandatory for large companies on January 31, 2026, as no IT system is 100% reliable.
- The Ministry of Finance’s IT Center acknowledges the problem but cannot guarantee it will be fully resolved.
