You can use the recurring appointment feature to book appointments for clients when you have them on a cycle.
Choose the following details to create the series of appointments:
Number of days, weeks, months, years.
How long do you want these to repeat
Auto confirm all future appointments - As explained in the video please exercise caution with this feature as if you choose this feature your clients will receive a booking confirmation for EVERY appointment straight away.
Any appointments that are showing as "unconfirmed" have not yet been sent to your clients. They will need confirming before the client receives details of the appointment.
