Hey there, ckennedy1.

Let me provide and help you with populating the correct quantity in your back-order columns in QuickBooks Desktop.

In order to show the correct quantity in your back-order columns, create a sales order and save it.

After that, create the invoice from the sales order. This will populate the correct back-ordered quantity in your template column.

Here's how:

1. From the Sales Order, click Create Invoice.
2. Choose to Create invoice for selected items.
3. Hit OK.
4. Enter the correct quantity.
5. Hit OK again.
