Functions to the manufacturer: buys in bulk and pays promptly; stores goods (warehousing), saving space; bears risks of price changes and damage; finances production by advance payment; gives market information; advertises products.
Functions to the retailer: breaks bulk into smaller quantities; gives credit; supplies a variety of goods from many producers; delivers goods; gives advice on new products.
Functions to consumers: stabilises prices and ensures steady supply by holding stocks; processes, grades, packages goods.
Discussion: critics say wholesalers raise prices and hoard, but their services make distribution efficient.
