SERVICE REP and PO# are not available.  Also the SERVICE DATES for each line item.  These are all very major categories needed on our invoices.  

Another detail - We use the Invoice # QB gives as our PO number when ordering parts for tracking, tech needs to SAVE invoice in order to have an Invoice Number assigned.  No problem, however once invoice is SAVED, program takes tech back to the HOME screen and does not allow any further updates to that invoice without having to look up the customer again and locate the invoice he was working on.  Very cumbersome.
