Partnership Marketing is the fifth and highest level of a customer relationship that a company can have with its customers. The company works continuously with the customer to ensure that the customer gets even more out of the product. The seller really takes the role of a consultant. The seller completes the product as it were. An example is a technology company that sells highly specialized machines. A few days a month a technician from the manufacturer comes by to monitor and improve the performance of the machine. In partnership marketing, the advice is often given at a strategic level on how the products of one company can make the other company even better. The concept of partnership marketing comes from the management model of the 5 levels of customer focus. Partnership Marketing actually only occurs in B2B relationships. This form of marketing is too expensive for B2C.
