The five Cs stand for customer, company, competition, collaborations, and climate.
The five Cs have many of the same concerns as the four and five Ps in certain ways, but they place more of an emphasis on external variables, including potential external partnerships and competitive research.
Moreover, "customer" refers to the target market and the customer experience, whereas "climate" refers to the social, political, and economic backdrop around the market. In contrast, "company" refers to the organization's position and its resources in the marketing process.
