Suppliers provide inputs that the firms in an industry need to create the goods and services that they in turn sell to their buyers. A variety of supplies are important to companies, including raw materials, financial resources, and labor ("Suppliers" [Image missing in original]). For restaurant firms such as Subway, key suppliers include such firms as Sysco that bring various foods to their doors, restaurant supply stores that sell kitchen equipment, and employees that provide labor.
The relative bargaining power between an industry’s competitors and its suppliers helps shape the profit potential of the industry. If suppliers have greater leverage over the competitors than the competitors have over the suppliers, then suppliers can increase their prices over time. This cuts into competitors’ profit margins and makes them less likely to be prosperous. On the other hand, if suppliers have less leverage over the competitors than the competitors have over the suppliers, then suppliers may be forced to lower their prices over time. This strengthens competitors’ profit margins and makes them more likely to be prosperous. Thus when analyzing the profit potential of their industry, executives must carefully consider whether suppliers have the ability to demand higher prices.
Every industry is unique to some degree, but some general characteristics help to predict the likelihood that suppliers will be powerful relative to the firms to which they sell their goods and services. Suppliers tend to be powerful, for example, to the extent that the suppliers’ industry is dominated by a few companies, if it is more concentrated than the industry that it supplies and/or if there is no effective substitute for what the supplier group provides. These circumstances restrict industry competitors’ ability to shop around for better prices and put suppliers in a position of strength.
Supplier power is also stronger to the extent that industry members rely heavily on suppliers to be profitable, industry members face high costs when changing suppliers, and suppliers’ products are differentiated. Finally, suppliers possess power to the extent that they have the ability to become a new entrant to the industry if they wish. This is a strategy calledforward vertical integration. Ford, for example, used a forward vertical integration strategy when it purchased rental car company (and Ford customer) Hertz. A difficult financial situation forced Ford to sell Hertz for $5.6 billion in 2005. But before rental car companies such as Avis and Thrifty drive too hard of a bargain when buying cars from an automaker, their executives should remember that automakers are much bigger firms than are rental car companies. The executives running the automaker might simply decide that they want to enjoy the rental car company’s profits themselves and acquire the firm.

Flash of Genius
When dealing with a large company, a small supplier can get squashed like a bug on a windshield. That is what college professor and inventor Dr. Robert Kearns found out when he invented intermittent windshield wipers in the 1960s and attempted to supply them to Ford Motor Company. As depicted in the 2008 movie Flash of Genius, Kearns dreamed of manufacturing the wipers and selling them to Detroit automakers. Rather than buy the wipers from Kearns, Ford replicated the design. An angry Kearns then spent many years trying to hold the firm accountable for infringing on his patent. Kearns eventually won in court, but he paid a terrible personal price along the way, including a nervous breakdown and estrangement from his family. Kearns’s lengthy battle with Ford illustrates the concept of bargaining power that is central to Porter’s five forces model. Even though Kearns created an exceptional new product, he had little leverage when dealing with a massive, well-financed automobile manufacturer.
