Appointment Booking Cowlendar

So far it integrates well with our site - with the only thing missing being exchange calendar integration, but we've chatted with the team, and its on the way. I like the customizability of the calendar display and so far the customer service is excellent. Have chatted a few times and have always gotten a quick response from either the main developer or the staff. Recently, I was on with Theo and he was accommodating!
