A vendor is a person or company that sells goods or services to customers. Vendors can operate in various settings, such as retail stores, markets, or online platforms. They play a crucial role in the supply chain by providing products that meet consumer needs. Vendors can be classified into different types, including wholesalers, who sell in bulk to retailers, and retailers, who sell directly to consumers. Some vendors specialize in specific products, like food vendors at events or software vendors in the tech industry, offering a wide range of options for buyers.
