TidyCal

Tidy cal is SO easy to setup. The hardest part was just getting my marketing wording correct. The rest was a breeze and it looks really nice when done.

You can have one appointment type or many. You can reference many calendars for available booking slots.

Tip if you have multiple accounts of a single type. Add the first account. Then log out of the account in your browser. Then add the second account. Otherwise, it just uses the first account you are already logged into over and over and doesn't give the option to enter a new account.

The only thing I don't like so far is that I can't customize the appointment confirmation emails. The booking confirmation emails TidayCal sends to me as the provider are beautiful and very easy to read. But the appointment confirmation emails sent to my customers are ugly and hard to read because there is no formatting (bold, size differences, etc.)

***To the AppSumo team, please make those look equally as nice as the Booking Confirmation emails!*** Or at least let us customize them ourselves, even at a global level that would apply to all of our appointments. They don't set a very good impression.
