Supporting New Black's global retail operations through a long-term development collaboration

Introduction

Since 2018, Wirtek and New Black have developed a collaboration focused on supporting the development and evolution of the EVA platform and its mobile applications, used by international retail brands.

As retail becomes increasingly connected across physical and digital channels, technology platforms play a critical role in helping retailers manage operations, sales and customer experiences across multiple channels, touchpoints and geographical markets. Through its collaboration with New Black, Wirtek contributes development expertise supporting the continued evolution of the EVA platform and its mobile applications. Its technology supports sales, logistics and customer engagement for tier-1 international retail brands.

New Black in brief

New Black is a technology company developing digital solutions for retailers operating across online and physical environments. The company focuses on helping retailers manage complex operations through integrated technology platforms that connect stores, online channels and customer experiences.

About the EVA platform

The EVA platform, developed by New Black, is a unified retail platform designed to connect key retail operations in a single engine. The platform supports capabilities such as point of sale, online commerce, inventory and order management, payments, and system integrations. By bringing these functions together, EVA enables retailers to operate digital and physical sales channels through one platform.

In 2025, New Black received the NRF Retail’s Big Show Europe award for Seamless Unified Retail in recognition of their platform. The EVA platform processed over 100M transactions in 2025, with compliance coverage across more than 44 countries.

Strengthening the mobile platform

When Wirtek joined the project, several technical challenges needed addressing. The codebase required continuous improvements and refactoring to prevent technical debt, the architecture needed attention to support scalability, and the overall stability of the platform needed strengthening.

In addition to improving the mobile applications built headless on EVA, Wirtek contributed to development work supporting the broader platform. This included helping integrate financial reporting processes required in different countries and supporting EVA’s ability to operate across international retail environments.

For this project, Wirtek’s work focused on:

• Mobile application development — development work supporting the continued evolution of the mobile application used by multi-billion euro retail brands.
• Platform stability improvements — strengthening code quality and architecture to improve reliability and scalability.
• International compliance integrations — supporting integrations that allow retailers using the platform to comply with fiscal and legal legislation across more than 40 countries.
• Platform documentation improvements — establishing documentation and shared knowledge resources to support development of a large and complex platform.

Results and benefits

Key improvements include stronger technical stability, improved application performance and a better overall user experience. As the technical quality of the application improved, headless-built consumer apps supported by Wirtek showed increasing ratings in the app stores.

Through the partnership, Wirtek contributes development expertise and technical insights that support New Black in delivering stronger technology solutions to its retail clients. This allows New Black to extend its delivery capabilities while continuing to support the growth and international operations of its customers.
