Distributors and wholesalers are businesses that purchase goods from manufacturers and other suppliers, store them in large warehouses, and then sell these items to retail merchants or directly to consumers. They play an essential role in the distribution chain by providing access to goods, efficient delivery, marketing and promotional services that enable retailers to reach a larger customer base. Along with this, they also provide value-added services such as product selection advice, customized packaging options and sales training. All of this helps ensure that goods get to the customers quickly and cost-effectively. As a result, distributors and wholesalers serve as key links between manufacturers and end consumers.
