Is there a way on Cojilio that a box can be checked before a payment is made to book an appt that says "I have read and accept the conditions of the cancellation and disclaimer policies."
Yes, this is set in the Cancellation Policy of the service. Clients will have to check the box that they have read and understood the policy you have set.
This is set in Service Details > Cancellation section. Here is a Help Guide: Set a Cancellation Policy on a service
When someone pre books a session on Cojilio and wants to cancel before the 48 hour "cancellation" policy is in effect, Is there or can there be a cancellation option on their confirmation? Or Do we, the business have to cancel them manually?
If a client books a service that has a cancellation policy of 48 hours, they are able to cancel/reschedule their own appointment on their own up until 48 hours before the appointment.
Once their appointment is within 48hours, clients will still be able to cancel their appointment if they agree to pay the cancellation fee set on the service. To avoid the cancellation fee, they can call in to cancel their appointment and ask you to waive the cancellation fee.
