I have been helping out a local charity (Coventry Refugee and Migrant Centre) to streamline their entire therapy services processes. It has been around a year of intermittent development but we got to the final destination eventually. The database is being used by about 8 staff members to gather and manage appointments, generate reports, invoices and related back-office tasks (the time consuming boring ones). The entire system is deployed on the local server with the ability to allow remote access in the future. Or it could be just migrated to the cloud altogether. Responsive design is supported out of the box so you can use it on a smartphone or tablet if you choose to do so.
Update (27 May 2020): Will be upgrading the database to allow the therapists to upload and manage documents of their clients.
