First, are you using QBO or QuickBooks Desktop?

In QBO, I create an item for freight, or trucking or shipping, and link it to the freight expense account.  Enter the amount of trucking or freight as a minus amount.  Actually, I use the same method in desktop.  I do bookkeeping for a number of farmers so can help you get it set up properly.  The same situation applies to sales of cattle through the sales barn where some taxable deductions are applied to the sale price.  This allows you to track the sales tax amount of the expense as well.
