Overriding the billable setting for your reservation
When calculating the duration we take any whole or part days and work out how many BILLABLE days.
For example if a duration is 3 days and 6 hours then the BILLABLE days (ie the quantity used in the price calculation) is set to 4, ie we round up.
Sometimes you may want to be kind to your clients and round down to the nearest day (or round up), i.e. give them the 6 hours for free, and call it 3 days billable.
You can easily do that by simply overtyping the billable days field.
