- KSeF was meant to simplify invoicing, but in some cases it made processes more complex and required extra staff to operate it.
- Both businesses and tax authorities are still learning how to use KSeF in practice, and interpretations of its rules often differ.
- The biggest technical issues appeared at the start with large taxpayers, mainly due to overload in connected systems rather than KSeF itself.
- Implementation costs vary: very large companies face very high integration and process-change costs, while small firms often only pay slightly more for accounting software subscriptions.
- The system will likely keep evolving, and in a few years taxpayers will face another major change with the EU e-invoicing system VIDA.
