Choose Sales Order Lines when converting to Invoice (See figure 2 above)
QuickBooks 2015 for Premier (and above) now offers an enhanced feature for converting Sales Orders to Invoices. Previous versions required you to put a quantity of zero for lines that were not to be included in the invoice total; however, those lines transferred to the invoice even though they had zero in the amount and so you were required to manually remove them.
The newly enhanced feature now includes a check-box to the left side of the items, this check-box permits you to select only the specific items you want to be transferred to the invoice. In this way you can avoid sending zero dollar items to the invoice.
