Troubles Connecting with the Fiscalization Service?
Czechia is reintroducing the electronic registration of sales (elektronická evidence tržeb) as EET 2.0, with the pilot starting on 1 January 2027 and full operation from 1 February 2027. The system of the Financial Administration (Finanční správa ČR) provides a web service to which your application must send signed XML messages - which can be a significant challenge full of pitfalls, especially for those without prior experience in web services, TLS, XML signing, and the management of certificates and cryptographic keys.
Fisver-CZ API and Fisver-CZ Proxy handle these complexities for you, allowing you to focus on other development tasks.
Fisver-CZ API
A software module for integration into your existing Java invoicing applications. Fisver-CZ API provides an object model for communicating with the EET 2.0 service, managing sales, signing requests, and processing the acknowledgement code (POK).
The ideal solution for Java-based applications. [Details]
Fisver-CZ Proxy
Fisver-CZ Proxy is a standalone service installed on your infrastructure that connects to your existing application via HTTP. It significantly simplifies the process by handling message signing and the verification of acknowledgements on your behalf.
The ideal solution for non-Java applications. [Details]
Other countries
Similarly, fiscalization solutions are also available for Croatia, Slovenia and Montenegro.
Support for additional countries will be added as fiscalization is implemented across them. [Details]
