What is one of the four groups of intermediaries?

Manufacturers are entities that produce goods, typically using raw materials and labor to create finished products. While they are essential in the supply chain, they do not serve as intermediaries; rather, they are the originators of products before they reach wholesalers and retailers.

Developers generally refer to individuals or companies involved in creating or enhancing products, particularly in industries like real estate or software. They do not fit within the category of intermediaries, as their primary role is to design and produce rather than distribute products to consumers.

Consumers are the end-users of products who purchase goods and services for personal use. They represent the final stage of the supply chain and do not function as intermediaries within the distribution process, which instead involves entities that facilitate the movement of products from producers to buyers.
