A guest may be booked in for a particular service, but when they arrive at the salon they may have a different service performed. Currently, we have to change the appointment in the appointment book screen to reflect the changes (upgrades/changes/downgrades) before we can pay the appointment. Could we please have the ability to make the changes in the pay screen, and in turn this then update the appointment book to reflect what has actually been charged for. If the stylists forget to change the appointment before paying we get left with appointments that are checked in but never appearing as paid.
