A delivery specialist works with customers to answer questions they may have before buying a product or service and ensure purchased items are delivered on time. Once the delivery or installation is complete, delivery specialists provide customers with more information on how to use the product or how to use their services. For example, delivery specialists at car dealerships run through the specifications and additional features of a car with interested buyers before, during, and after the purchase, then make sure the customer receives the correct vehicle. There are no formal education requirements to become a delivery specialist, but many employers prefer candidates with experience in sales or customer service.
