Your customer wants you to deliver a partial order, but wants only one invoice for the complete order, not a separate invoices each time some items are shipped.
The B type invoice can be used for this purpose. The total value of the order is charged to the customer's account, while it tracks the items that are still on backorder.
This tutorial explains how to set up and use the B Type or accounts receivable invoice with backorders.
