Like Hyperbytes (Brian) we have developed many Property Management solutions including Support/Maintenance provisions. Can get an idea from this Showcase from last year:
As well as the Support Platform above we have a deployed a full suite of solutions for Property Management companies that allow Clients to observe all aspects of their Property activity from Accounts, Tenants, Guests, Reservations, Support, Sales, and After Sales services (plus lots of other solutions such as API connectivity, and now a cross-over in to deploying the same to Mobile Applications for Android and IOS). Back-end is Apache/NGINX/MySQL powered. Low overheads, great performance.
You can achieve what you are after with Wappler with a little time and effort. Welcome to the forum and Wappler Chris!
