Supplier

Supplier is a company, person, etc. that provides things people want or need, especially over a long period [Cambridge Online Dictionary].
A supplier is a person, organization, or entity that provides something another person, organization, or entity needs. During transactions, there are suppliers and buyers. Suppliers provide or supply products or services while buyers receive them. We commonly use the term ‘vendor’ with the same meaning as ‘supplier.’ In business, for example, every company has at least one supplier. Suppliers supply or provide the company with materials, products, and services. Supply chain management, or SCM, manages the flow of products and services. It is a business term.
SCM involves the movement and storage of raw materials, work-in-process inventory, and finished products from origin to consumption. ‘Suppliers’ or ‘vendors’ are supply chain management terms. The terms mean entities that provide goods or services to individuals or companies. Suppliers may, for example, manufacture inventoriable items and subsequently sell them to customers. The supply chain is the whole process of making and selling commercial products. It includes every stage, from the supply of raw materials to delivering the product to the ultimate consumer [MarketBusinessNews.com].
