We would love to see more intelligence when it comes to the automatic settlement policies. For example if we have a booking that pays 25% at time of booking, and 75% a week before arrival, the system will not take into account any payments made in between those two events. If the customer decides to pay their booking early, we rely on human intervention to cancel the scheduled payment, or the guest will get charged twice. We also have the option to close the bill to avoid re-charging, however this is impractical for us due to other complications with closed bills during the guest stay.

Ideally - the system would read the balance of the booking (balance of the booking - not of the profile, in case guest has multiple bookings) and charge accordingly. So if no balance remains, the guest would not get charged.
