Is there any plugins/stacks for a Professional outpatient practice or a clinic ?

I presume you need a booking system? The only opions I have seen are php scripts that can be incorporated into a web page. It’s easier on Wordpress pages as you can add them as a plugin. It is something I have wanted for a while now and there is a gap in the market for a booking stack.
