Drop shipping is a supply chain management technique in which the retailer does not keep goods in stock but instead transfers customer orders and shipment details to either the manufacturer, another retailer, or a wholesaler, who then ships the goods directly to the customer. An online drop shipments company wants to create a system to allow customer and suppliers to register. A supplier can add products that it sells. A customer can buy products that are up for sale. Suppliers ship products to customers if they are in stock.
