In the event that a client has had a different service to the one they were originally booked in for, you need to Edit the service in POS to ensure that the service is also changed on the Appointments page.
NOTE: You can't delete the service listed in POS, and then add back a new one, because the one on the appointments page won't be paid for.
How to change a clients service in POS the right way
Add the client to the sale and click the row the service displays in.
On the right side panel, change the service via the Category and Service drop-down menus.
Once you've picked the service, which the client actually had done, click Save.
The service will be updated in POS.
Click Receive Payment, choose payment type and Finish Sale as per normal.
This process changes the service on the Appointment page as well. This is the correct way of changing the client's service if they had something different to what they were originally booked in for.
