I have worked with Over & In for over 10 years on all manner of design and web developments.
The latest web development and design in 2019 needed to feature a way for parents to enter their children onto Tennis and Football group coaching lessons. This data then needed to be stored and accessible via a register app on the day of the coaching as well as the ability to export spreadsheet registers. The extra information required for each attendee also need to be accessible. To do this we used a combination of Woocommerce and FooEvents.
The design also needed to show a clear distinction between Football and Tennis which we did by use of different menus depending on the selection and also colour profiles.
