I like that it only took me 1 hour to set up my TidyCal bookings options, connect it to my Outlook calendar and test it to make sure that is works the way I want it to. Previously, I have spent countless hours trying to get my booking application(s) to not schedule over other appointments to no avail. Those other systems required much more time to set up and still did not work properly. I'm so happy with the simplicity of TidyCal and the one time license purchase! Thank you.
