Late Invoices, Lost Money --Dickeson

But, if you're using electronic job ticketing, how can this ever happen—unless you lose your computer and its server? The only possibility then is that someone may fail to input customer changes in the original order.

We've now solved two problems: Count and Lost Job Tickets. What else? Customer changes, again. These are changes in the original order that may, or may not, modify the invoice. Either you're using an electronic job jacket system or you aren't. If you aren't, it's easy for someone in customer service, or somewhere else, to have forgotten to note the change or to just be "sitting" on the change information.
