If you have appointments that are at unique times on your calendar, you can use the Default Appointment Length and Time Selector Interval in your Appointment Settings to achieve the result you want on your Booking Form. This will give your customers the ability to select the right booking times without you needing to adjust the timing or appointment length of every appointment on your schedule.
To set up an appointment that occurs every 45 minutes on your Booking Form, you'll need to do the following:
Click on Settings > Appointments.
In the Default Appointment Length menu, select 45 minutes.
In the Time Selector Interval menu, select 15 minutes.
Click the Save button to keep the changes.
Once you have made these changes in your Appointment settings, your clients will be able to select appointments 45 minutes apart on the Booking Form.
We also suggest setting up your Booking Style in your Booking settings to Appointment Request. This will allow you to approve the requested appointment times that work for your business schedule and disregard the ones that don't.
