Middleware solution

fiskaltrust's middleware platform simplifies integrating multiple countries and baseline features into POS software. It supports different markets with a direct mapping from the POS system to the middleware, minimizing the need for customization. The middleware abstracts away fiscalization and payment logic, providing a clean interface for developers to work with.

Open source approach

The middleware is open source, which means that the code is publicly available on GitHub for anyone to contribute to. This approach reflects fiskaltrust's values of trust, fairness, and openness. We believe that working with partners and the community is the best way to achieve mutual benefit and success.


The open source approach has several benefits for businesses and developers. By contributing to the middleware, businesses can help shape the direction of the project and improve its functionality. Developers can leverage the middleware to simplify compliance efforts and focus on their core business. The platform's partner-based approach also provides access to a network of over 500 integration partners and 800 commercial partners who distribute the middleware to more than 100,000 merchant outlets and process over 3 million unique receipts per day.
