You can limit when your client can reschedule an existing appointment with you, but they can cancel their appointments at any time by logging in to their account in Booksy and selecting their appointment. Prevent cancellations and protect your bottom line by adding No-show protection to your services. Make changes to your Booking Rules by going to your Business Settings (mobile: Profile → Settings) → Advanced Options → Booking Settings. You will receive a notification whenever your client makes any change to an existing appointment.
