- Companies must manage invoices both within and outside the KSeF system, leading to accounting challenges and risk of double-booking.
- Invoices are issued in multiple formats: structured XML in KSeF, electronic PDFs, and traditional paper, and this will continue until the end of 2026.
- Some businesses avoid KSeF by issuing simplified invoices (receipts up to 450 PLN), which remain outside the system.
- Duplicate invoice delivery (via KSeF and email) causes confusion and increases the risk of errors in accounting.
- System login failures and incomplete invoice data in KSeF add to the uncertainty, with regulations lacking clarity on these issues.
