Thanx for the answer. I have a follow-on question. We pay sales commission based on the cash receipts. In the above scenario let's assume an invoice is dated in January, the cash was ACTUALLY received in March, but not credited to the invoice until July. I am concerned that the system will (despite the books being long closed for March) record this as a cash sale in March. How do I get this 'fix' to show the cash sale in July; the month the issue was resolved?
