the ability to prepay a purchase invoice if the actual costs is relevant to a different period/date than what it is posted to. this could be something paid for as a one off in advance, or a service for the full year.
The ability to use this within Draycir invoice recognition - even if that requires manually inputting the service dates.
Similar function as to what is in Sage X3
Thanks for the comment - could you help us understand why the pre-payment functionality doesn't work?
