Apart from computing sales commission on posting of a sales invoice, can we have an option to compute commission based on settled (paid / matched) sales invoices?  We are receiving this request quite often from customers and the idea is to pay a commission to the salesrep when the customer pays for the sale invoice.  There are good reasons for this method of commission computation including reducing fraud, addressing sales bloating to meet end-of-month commission targets, etc

System should compute commission on part-settlement as well as reverse commission if invoice is unsettled / unmatched.  A method to accrue for commissions to be paid is also appreciated
