Freight is not taxing correctly for a freight only charge
In the special case where there is no merchandise charge (so the ONLY charge on an order is for freight revenue), freight is not taxable - even if freight is normally taxable in a particular state. This is not happening.
Freight will always use our freight depends logic if this is invoiced a state that has that tax law. Georgia is one of those said states.
This makes the taxability of freight directly correlate to the ratio of taxable and non taxable line items in any given invoice.
