Drop shipping is a retail method in which you don't keep products in stock. Instead, you partner with a wholesale supplier that stocks its own inventory - you transfer customer orders and shipment details to them, and they ship the goods directly to the customer. The biggest benefit of drop shipping is you don't have to worry about fulfillment or inventory issues. Also, most customers don't know you're drop shipping, since "private label shipping" lets you ship from the wholesaler with a return address and invoice customized to your ecommerce store.
