Billing after appointment#1661

We are a doctor’s office that needs to bill patients AFTER the visit. We cannot use the standard payment for all services. We get a better idea about their bill after the consulting. We need to be able to edit the bill soon after the appointment so adjust the amount to be paid. Thsi can simply be acheive if we were to be given edit access to the “Edit appointment screen” (attched) and perhpas also the employee appointment view screen.
