A vendor is a person or company that sells goods or services to customers. They can be found in various settings, such as markets, stores, or online platforms. Vendors play a crucial role in the supply chain by providing products that meet the needs of consumers. For example, a food vendor at a local fair sells snacks and drinks to attendees. In addition to selling products, vendors often build relationships with their customers to encourage repeat business. They may offer promotions or discounts to attract buyers. A retail vendor might provide a loyalty program, rewarding customers for their continued support and purchases.
