Which term refers to a business that sells products to another business?

The term "Supplier" is used to describe a business that sells products to another business. In a business-to-business (B2B) context, suppliers provide goods or services that other businesses need to operate, manufacture their products, or sell to end consumers. This relationship is essential for the supply chain, enabling businesses to source the necessary materials to function effectively.

In contrast, customers typically refer to end users or individuals who buy products for personal use, while consumers are the final users of goods and services. A retailer, on the other hand, purchases products from suppliers or manufacturers to sell directly to consumers. Therefore, the best fit for a business that sells to another business is the supplier, as they are directly involved in facilitating the needs of other companies.
