Vendor

A vendor, also known as a supplier, is an individual or company that sells goods or services to someone else in the economic production chain. Vendors are a part of the supply chain: the network of all the individuals, organizations, resources, activities and technology involved in the creation and sale of a product, from the delivery of source materials from the supplier to the manufacturer, through to its eventual delivery to the end user.

Parts manufacturers are vendors of parts to other manufacturers that assemble the parts into something sold to wholesalers or retailers. Retailers are vendors of products to consumers. In information technology as well as in other industries, the term is commonly applied to suppliers of goods and services to other companies.
