UNRELIABLE Today I got a message that my booking system was down. Instead of informing me that my live link was down calendly has just been letting the URL bounce for who knows how long because they wanted me to upgrade my plan. I have no idea how much money this cost me but I'll never recommend this service to anyone. Incredibly poor handling and I'll be sure to mention this at every Miami tech event I find myself at.

Filtering by email only. Filtering by email only. A customer calls up she wants to reschedule her appointment, I can't find the customer and I can only filter by email I cannot even filter by our first name or last name or her phone number only by email. Such an easy task for such a big company. Don't makes sense. When you look for an appointment, it should be easy to just look it up by putting in a person's name or phone number.

Absolute trash Absolute trash. The Optometry practice I work at uses this and it is utter rubbish to use! It's clunky, not user friendly, it doesn't sync with calendars properly so there are always conflicting or double bookings which ends up causing numerous complaints from patients. I would not recommend this as it is poorly written.

It can be used for basic things It can be used for basic things, but for more serious use it lacks some important features or simply doesn't work as expected. E.g. for sms notifications the guest reconfirmation only works once per guest address, you can't book a meeting from the admin page, etc. The chat support is nothing but a basic AI chatbot. All in all it doesn't cost much, the sms notifications make it worth the price, but it could be much better.

not user-friendly design and useless support Fantastic support response time! Still waiting on a solution after 48 hours... It was impossible to update my availability in a way that actually affected the booking link! This design is infuriating! It creates nothing but frustration when trying to manage event availability. Who designed this? Did they even consider usability? The whole process is hidden and convoluted. It takes forever to find the event, then unearth the availability settings buried in some obscure menu. Fix this mess before it drives everyone crazy!
