Late Invoices, Lost Money --Dickeson

There's one thing about customer changes that will affect the final invoice total. Either the changes have been accepted, and a dollar value placed on the change, or there hasn't been. If there's no documentation of the change, and customer acceptance of the charge, then it should not be invoiced. In this day of e-mailing I can't think of one good reason why there should not be, at the very least, an e-mail record of change orders. Can you? If there is an e-mail documentation, then it must be saved in a file for the invoice. If you're using an electronic job ticket, then the e-mail exchange must be saved in that ticket file.
