Integration with the KSeF system is a topic that in the coming months will become one of the biggest challenges for entrepreneurs in Poland. From 1 February 2026, the obligation to use the National e-Invoices System will cover companies with annual revenues exceeding PLN 200 million, and just two months later – from 1 April 2026 – the system will become mandatory for all enterprises.
This is a revolutionary change in how invoices are issued and processed. Every invoice will be generated and stored in KSeF, which requires companies to adjust their financial and accounting systems. However, a well-executed KSeF integration will not only allow compliance with legal requirements, but also significantly simplify a company’s financial processes.

What is KSeF?
KSeF (National e-Invoices System) is a central platform from the Ministry of Finance of Poland for issuing, sending, receiving and storing structured invoices. From 1 February 2026 it will gradually cover all companies and entities issuing invoices in Poland.
The implementation aims at the full digitisation of invoicing and accounting processes, easier tax-control, and greater document-flow security. To enable full integration with KSeF, the Ministry recently released the KSeF 2.0 API documentation, which allows integrators and IT companies to begin connecting their systems to the national platform.
Thanks to this, Sparados SA can already today implement features of automatically retrieving invoices from KSeF and linking them with the correct transaction.
What is the Sparados system?
Sparados is an innovative fintech platform for managing corporate finances, enabling, among other things, issuing virtual Mastercard business cards for employees and contractors. It’s a modern tool supporting companies in expense control, payment analysis and accounting-process automation.
The Sparados team continuously develops new functionalities in the client panel and mobile application. Besides integrations with accounting systems, invoice-processing automation and the expansion of the lunch-card offering, the fintech startup already now provides full integration with KSeF via the KSeF 2.0 API. Thanks to this, Sparados bridges the world of banking and accounting, creating a link between transaction and invoice. It’s a solution preparing Polish companies for the digital revolution and facilitating the transition to invoicing in KSeF.

Banking-to-KSeF Integration – How Sparados Automates the Invoicing Process
The new regulations force companies to integrate their financial systems with KSeF. One of the biggest challenges is the automatic matching of invoices with payments — for example card transactions or bank transfers.
“Sparados, as the first fintech in Poland, offers a system that can automatically retrieve e-invoices from KSeF, analyse them and link them to financial transactions. Thanks to this, entrepreneurs no longer need to manually match data or verify payments,” emphasises Michał Stachera, CEO of Sparados.
By implementing full automation, Sparados meets the real needs of B2B companies and their accounting departments. In practice it means the end of guessing which invoice applies to which payment. Your accountant will literally thank you – every bank statement is supplemented with the unique KSeF invoice identifier (mandatory from 2026), which allows clear linking of the invoice with a specific transaction.
Thanks to the Sparados solution, accounting receives a ready-made, complete transaction file with the invoice number, supplier name and tax ID, which reduces time on journal-entry work practically to zero.
The system automatically eliminates all common accounting questions: “Where is this transaction from?”, “Could you send the invoice for operation X?”, “Do you have a payment confirmation?”, “Which transaction is this invoice connected to?” - Our platform provides a complete information set directly on the bank statement, so the data no longer requires additional verification or email communication with accounting.
Additionally, Sparados simplifies cost tracking – each invoice is enriched with supplier data, and the system allows instant searches of all invoices from a single vendor based on information provided directly from the bank account. Thanks to this, companies gain full transparency and their financial processes become predictable, fast and error-free.
Thanks to the banking-to-KSeF integration, the Sparados system independently recognises which invoices have been paid and which require a reminder. It is the end of tracking inflows and perpetual spreadsheet checking – now the process is fully automated and you can focus on scaling the business, not on administration.
