It would be good if, within the account options section there were the ability to apply a discount rate or a factor of charge rate, for example if we wanted to apply a 25% discount against an account if we could enter either the value 0.25 or 0.75 depending whether we said apply a discount of 25% or apply rates at 75% the normal rate.
While considering this it would also be useful to be able to time limit this if desired so have an additional field where a value could be entered. If no value then the reduction would be ongoing but if a value entered then the discount would only apply to bookings made within that number of days ie for a month we could put in 30 and then after that time it would expire and bookings would be charged at the normal rate agains
