The challenge
Digitise the issue, checking and tracking of family vouchers and senior citizens’ vouchers, while giving recipients a way to receive and use them in local shops.
The solution
Aurélien and Aymeric spent three years developing a system that combines an administration interface with a mobile application. The solution supports voucher management and use, and also includes tools for association members, fees and registrations.




With an ambitious project and tight deadlines, we were looking for a partner who could understand our expectations. SOLIS succeeded and even supported us in areas where we had not expected their help.
An administration platform for tracking vouchers
The work covered the full management process: issuing vouchers, checking them and tracking their use. The interface gives administration teams a common tool for running the municipal scheme.
The scope also includes the management of association members, fees and registrations. These needs were incorporated into the system in collaboration with the project’s stakeholders.
An application for recipients
The mobile application complements the administration platform: it lets people receive vouchers and use them in local shops. The two parts of the project serve different users within the same scheme.
Delivered in 2024 after three years of development, OZAM combines Node.js, React Native and MySQL. Aurélien and Aymeric delivered the project in collaboration with the stakeholders involved.

Let’s discuss your project
Do you have a similar project?
Your custom application project
Audit, scoping and prototype
Together, we clarify the need, users and objectives, then create an initial clickable prototype to define the user journeys and essential features.
Essential features (MVP) and product roadmap
We define the essential features (MVP), then organise V2, V3 and future development around feedback, ambition and budget.
UX/UI and scalable architecture
User journey design, native or cross-platform technology, backend, APIs, database, administration when needed, security and performance: every decision prepares the application to grow without starting over.
iOS and Android development
We develop the iOS and Android application, incorporate your feedback and advise you throughout the project, with clear tracking of progress and hours.
Testing and app store publication
We test and optimise the application, prepare the accounts, product pages and forms, submit it to the App Store and Google Play, then work with you on the feedback and requested changes.
Production launch and future releases
We configure the production launch, hand over access and technical materials, and can then provide maintenance, support and the following phases.
Public launch plan
(Optional)For a public release, we can organise the waiting list, beta, newsletters and launch calendar to bring the first users together—just as we did for Kinn.
