Abstract: Systems and methods allow small businesses and other buyers to aggregate their purchases to obtain volume discounts from suppliers. The systems are especially beneficial to small businesses that may be unable to obtain any discounted price on their own. The systems reduce transaction costs, improve efficiencies, increases revenue, and provides a more accurate process to buyers and suppliers. The systems are preferably operated by an entity that already has relationships with many of the small businesses and other buyers and possibly with one or more of the suppliers. The operating entity enjoys the reduced prices and other buyer benefits and may additionally receive rebates or extra discounts from the suppliers. The operating entity also can generate goodwill with its existing customers, retain those customers, and acquire new customers.
