SmartKSeF at the EFL Group – an Effective Response to the Challenges of KSeF

The implementation of the National e-Invoicing System (KSeF) in Poland has been postponed to 1 February 2026 for enterprises whose sales in 2025 exceed PLN 200 million, and to 1 April 2026 for all other entities. Businesses are now facing a range of challenges in adapting their financial and accounting systems to meet the new requirements.

Key obligations include integrating invoicing processes with the government’s KSeF platform, ensuring the accuracy of transmitted data, implementing robust information security procedures, and continuously monitoring legislative and technical updates. In addition, companies must train their finance and administrative teams to ensure full compliance with the new regulations.

This is precisely why the EFL Group, a leading player in the leasing market, has chosen SmartKSeF as its tool for communicating with the National e-Invoicing System. The decision was primarily driven by the flexibility of the solution, its ability to be tailored to specific organisational needs, and the assurance of the highest IT security standards.

SmartKSeF is a comprehensive solution that enables seamless integration with the EFL Group’s existing financial and accounting systems. With its advanced reporting and analytics features, users can effectively monitor and manage electronic invoices, enhancing operational efficiency. The solution is fully compliant with the latest legal requirements and supports all types of e-invoices in one place. An additional advantage is its transparent API, which allows for smooth integration with the current IT infrastructure.

Despite the absence of previous collaboration with the EFL Group and the specific nature of the leasing industry, the expertise of the implementation team and the adaptability of the solution made SmartKSeF the ideal choice. The team’s commitment, proactivity, and high standards of cooperation ensure that the EFL Group receives reliable support throughout the entire implementation process and in ongoing system operation.

We warmly invite organisations facing similar challenges related to KSeF implementation to get in touch and benefit from our experience and the proven SmartKSeF solution.
