Study of global customer retention is an emerging trend in the industry. This chapter has proposed a novel model (GCP Model) to practice global customer retention. It aims to find the useful pattern with the combination of IFS, -cuts, expert knowledge, and data mining technique. This proposed model might have some limitations, for instance, some sensitive data of customers are not involved in it, and this will be the future research direction. With respect to the research findings, in order to maximize an organization's profits, policy makers have to retain valuable customers and increase the life-time value of the customer. As such, global customer retention is so important to maintaining a long term and pleasant relationship with customers according to different cultures and locations.
