Put a check mark next to the sales orders you wish to invoice. You may select all or just some of the sales orders. Click on “OK.”
Once you select the sales orders, QuickBooks gives you the option to invoice for all the items on each sales order, or you can create a partial billing.

The first option, “Create invoice for all the sales order(s),” will create an invoice for the full quantity of all items listed on the sales order.
The second option, “Create invoice for selected items,” will allow you to create a partial billing. In this instance, our supplier only sent us 3 of each item, even though we had ordered 5.

QuickBooks now creates an invoice for 3 of each of the items for which you are billing.

If you wish, you can include the backordered information on the printed invoice, or the invoice form can be customized to only show this information on the screen. The following sales order columns are available to include on this form:
