Evouchers is also an initiative of Wonde - a portal for managing school data - and it was initially created as a simple solution for schools and local authorities in the UK to procure, assign and distribute grocery vouchers during school holidays or self-isolation during the 2020 Coronavirus pandemic.

Since its launch, Evouchers have NOW supported the distribution of vouchers to over 750,000 families across 11,000 schools and 30 local authorities.

Project details

Wonde team was about to develop a few new ventures and side projects for their core business.

One such initiative was Evouchers for which they wanted to find a long-term partnership to support them with the current and future initiatives.

They built all of their desktop apps internally but decided to find a partner who will assist them with mobile projects.

One of the main project objectives was to build a mobile app both for iOS and Android, based on designs they made. They were additionally very keen to use React Native, as they've already used it in another project and wanted to keep the same stack everywhere.

  • Mobile App for both iOS and Android

  • React Native as a core mobile framework

  • Mobile development based on prepared designs

  • Long-term partnership

Searching for the right tech partner

Evouchers searched for an experienced React Native Team, and they were talking to 2-3 other agencies at the same time.

However, as they said, our experience seemed aligned with their expectations, and our response to the inquiry was super quick, which was quite impressive.

Even though they didn't work with an agency before, they liked our approach and the fact that we guided them through the cooperation process in a clear way.

From the first meeting, we have been asking the right questions and pointing out the challenges related to many functionalities. We also came up with initial solutions and presented our technology stack ideas, which the CTO liked and accepted immediately.

When selecting an agency, they paid attention to both experience and budget, and together with how happy they were with our approach to the project, they decided to hire us.

Planning Stage

One of the most important factors helping in the entire planning and development process was the fact that we spoke directly with the CTO and the decision-maker right from the beginning, so we could proceed much faster with decisions.
