As a vendor relationship manager, you oversee agreements with vendors that supply things to your company. In this context, a vendor can be anything from a company that provides raw materials to your factory to a delivery service that stocks vending machines. In this role, you may help evaluate existing agreements, negotiate favorable purchasing plans, and review pricing options to help get the best return on investment. This position often involves forming personal relationships with people at other companies. Some vendor relationship managers work in teams to handle larger groups of vendors.
