Drop shipping is a form of retail business in which the seller accepts customer orders without keeping stock on hand. Instead, in a form of supply chain management, the seller transfers the orders and their shipment details either to the manufacturer, a wholesaler, another retailer, or a fulfillment house, which then ships the goods directly to the customer. The seller is responsible for marketing and selling the product, but has little or no control over product quality, storage, inventory management, or shipping. By doing this, it eliminates the costs of maintaining warehouses – or even a storefront – purchasing and storing inventory, and employing necessary staff for such functions. As in any other form of retail, the seller makes profit on the difference between an item's wholesale and retail price, less any pertinent selling, merchant, or shipping fees accruing against them.
