A vendor, or a supplier, is a supply chain management term that means anyone who provides goods or services to a company or individuals. A vendor often manufactures inventoriable items, and sells those items to a customer. Typically vendors are tracked in either a finance system or a warehouse management system.
In sales, commerce and economics, a customer (sometimes known as a client, buyer, or purchaser) is the recipient of a good, service, product or an idea - obtained from a seller, vendor, or supplier via a financial transaction or exchange for money or some other valuable consideration.
