The invoice stamp mentioned is on the screen and cannot be removed from the template. The customer terms are Due Upon Receipt, that means there is not past due. I appears on reports as current or 0-30 which is our normal pick-up windows. And Of course it does, is not helpful and simply shows you did not consider what was being presented. Yes, if your due days is 0 then the invoice is past due on creation. That is clear and pointless.
