What is one of the four groups of intermediaries?

Manufacturers are the original producers of goods and are not considered intermediaries. They create products that wholesalers and retailers eventually sell to consumers. While crucial to the supply chain, manufacturers do not fit within the category of intermediaries, which specifically refers to entities that help move products through the distribution process.

Developers are typically involved in the creation and management of real estate or software products rather than in the distribution of consumer goods. They do not serve the function of intermediaries in the traditional sense of moving products from producers to consumers, hence they are not classified as one of the intermediary groups.

Consumers are the end-users of goods and services, and they are not intermediaries in the distribution process. They purchase products for personal use, and their role is at the final stage of the supply chain, contrasting with the intermediary function of facilitating sales between manufacturers and retailers.
