When a customer hires a shipping company to pick up product the customer has purchased and the customer pays the shipping company directly, the shipping company becomes the customer’s agent. As such, the actions of the shipping company are considered actions of the customer. The transaction is subject to sales tax because the product transfers to the customer/customer’s agent at the Tennessee seller’s location.
