The initial 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 delivered
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.
Behind the scenes of the project


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.

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.
