I have the same question,  we're planning to switch to online from Desktop by end of month 

need to have line item number in all invoices and estimates, as this helps a lot to review with customers and staff when go over the phone  regarding any of this docs.

makes it easy just to say  look at line # XX and advise. 

also how do you make the (ship via) window to show in invoice without having the (tracking No) window .  you should have the option.
