If the credit you provide is scarce or unique
Suppliers wield significant power if the item they provide is scarce or unique, or if there are only a few suppliers. They have considerable power to damage a competitive position. One response is to build close relations with important suppliers to secure delivery and control prices.
In the long term, the solution may be to move into the supplier’s industry to safeguard supplies.
The power of the customer is another source of competition. The issues that need consideration are how dependent the business is on individual customers, the ease with which customers can move to another supplier, the customer’s knowledge of the business’s competitors and the conditions (price, quality, overall offer) that are prevailing. The growth of the internet as a sales channel has empowered customers. In an increasingly networked, global marketplace, prices become transparent and it is much easier to discover when prices for the same thing are different in separate geographic markets. Price transparency became even more of a strategic issue for businesses in euro zone countries when they adopted a single currency.
