Custom KSeF client at LinTax

Our development team is intensively working on a custom KSeF client implementation. Instead of relying solely on third-party solutions, we decided to build a tool tailored to our clients' needs.

Why a custom solution?

  • Full control — immediate response to API changes and FA(2) schema updates
  • Process integration — tightly integrated with our document workflow and accounting system
  • Data security — client data doesn't pass through intermediary systems
  • Performance — optimized for our workloads

Timeline

We are currently in intensive integration testing with the KSeF production environment. We plan to make the solution available to our clients before 1 April 2026.
