Order Routine Specification.
After selecting suppliers, the buyer negotiates the final order, listing the technical specifications, the quantity needed, the expected time of delivery, return policies, warranties, and so on. Many industrial buyers lease heavy equipment such as machinery and trucks. The lessee gains a number of advantages the latest products, better service, the conservation of capital, and some tax advantages. The lessor often ends up with a larger net income and the chance to sell to customers that could not afford outright purchase In the case of maintenance, repair, and operating items, buyers are moving toward blanket con tracts rather than periodic purchase orders. A blanket contract establishes a long-term relationship in which the supplier promises to resupply the buyer as needed, at agreed-upon prices, over a specified period of time. Because the seller holds the stock, blanket contracts are sometimes called stockless purchase plans. The buyer's computer automatically sends an order to the seller when stock is needed. This system locks suppliers in tighter with the buyer and makes it difficult for out-suppliers to break in unless the buyer becomes dissatisfied with prices, quality, or service. Companies that fear a shortage of key materials are willing to buy and hold large inventories. They will sign long-term contracts with suppliers to ensure a steady flow of materials. DuPont, Ford, and several other major companies regard long-term supply planning as a major responsibility of their purchasing managers. For example, General Motors wants to buy from fewer suppliers who must be willing to locate close to its plants and produce high-quality components. Business marketers are also setting up extranets with important customers to facilitate and lower the cost of transactions. Customers enter orders that are automatically transmitted to the supplier Some companies go further and shift the ordering responsibility to their suppliers in systems called vendor managed inventory (VMI). These suppliers are privy to the customer's inventory levels and take responsibility for replenishing automatically through continuous replenishment programs. Plexco International AG supplies audio, lighting, and vision systems to the world's leading automakers. Its VMI program with its 40 suppliers resulted in significant time and cost savings and allowed the company to use former warehouse space for productive manufacturing activities.
