Dropshipping is a business model where retailers sell products online without keeping any inventory. Instead, when a customer places an order, the retailer purchases the item from a third-party supplier who ships it directly to the customer. The retailer profits by charging a higher price than what they pay the supplier. It's a low-cost way to start an e-commerce business since you don't need to manage stock or handle shipping logistics, but it requires strong marketing and supplier management skills to succeed
