How to Reverse a Checked-In Appointment
In the left sidebar, click the calendar icon to open the Appointments module.
Click on the checked-in appointment to open the appointment window.
Click the reverse icon at the top of the appointment window.
Confirm the reverse action.
Important: Reversing an appointment does NOT automatically annul the invoice that was generated at check-in. The invoice remains active and must be managed separately through the Billing module if needed.
