When a customer comes in the first thing they ask is "How Long"

Because of this there is no need to print the date and time due on the ticket. When the customer calls in to COLLECT the phone they get the invoice so there is definately no need to print it there either.
This means that you can use the "Description" box to highlight notes. Also when the customer brings the device back under warranty and has to produce the invoice, there is more detail showing without having to lookup the details
