Arranging for invoices to be approved by management is a messy and time consuming process that takes place before we are able to enter them on KF.
A nice idea would be the ability to store 'unapproved' invoices on KF (perhaps even with ability to scanned images of paper invoices). These invoices have to follow an approval process before they can be paid. A quick mechanism/report for managers to see and review these type of invoices.
