Galnaftogaz is a major Ukrainian fuel retail chain renowned for its "OKKO" branded gas stations. With a history of over 25 years, the company has steadfastly committed to delivering superior fuel products and unparalleled customer experiences. Galnaftogaz has over 400 fuel stations equipped with convenience stores and 15,000+ specialists who drive business success and promote business values daily. 


Obsolete Tech Stack

The outdated technology stack posed challenges when attempting to modify the POS solution and incorporate fresh features. It did not align with Galnaftogaz's aspiration to enhance customer experience through novel functionalities and services. Consequently, the company opted for an advanced, custom Point of Sale system to speed up the Time-to-Market for new offerings and surpass customer expectations.

Inefficient Service Delivery

Customers typically spend around 134 seconds at a fuel station's c-store, with 21 seconds dedicated to the check-out process. However, the client's outdated C-store POS fails to meet the competitive service provision speed due to its inconvenient UI and lack of essential integrations with third-party services.

UI Complexity 

Due to the outdated legacy interface, employees faced difficulties utilizing the existing POS solution. The mismatch between staff requirements and the software's UI features resulted in numerous errors, causing a noticeable decline in customer experience and financial losses.
In response to these issues, the company decided to implement a POS system with a native and user-friendly interface to improve employee experience and boost productivity.

Lengthy Onboarding Process

Using outdated convenience store pos software has resulted in a time-consuming onboarding process, employee burnout, and a high turnover rate. Additionally, the company faces the need to hire seasonal staff to accommodate fluctuations in demand. The extended onboarding period for new team members has negatively impacted the productivity of experienced employees (mentors) and necessitated significant investments in training beyond the standard requirements.


The JEVERA dedicated team has undertaken a sophisticated migration from a monolithic architecture to microservices, ensuring the delivery of the best retail POS system. The specialists have employed the parallel-run migration method to mitigate risks associated with a new system rollout. The most challenging part of the project was to build robust integration points with vital back-office systems to provide swift data exchange. 

The modern convenience store POS system is adaptable, allowing seamless integration with emerging technologies such as IoT and 5G. Its flexibility enables businesses to keep pace with the digital evolution. With a guarantee of system efficiency and relevance for over 10 years, this retail POS system provides long-term value and sustainability.
