It is possible to change/adjust the price of an online booking. An example of where this would be useful is, if your standard price for an appointment is €50 but it is €45 for a student. In this case, you cannot be sure that the person is a student until the physically present a valid ID to you. Therefore, they book the appointment at the standard price of €50. Once you have verified that they are in fact a student or a senior, you can revise the price down to €45. This 41 second video demonstrates how to go about this. It is a useful feature if you are using BookingHawk.com to track your business financials.
