What are the different intermediaries in business distribution channels? What roles do they perform?

What will be an ideal response?

Business market distribution channels are structured like those for consumer markets. Similar to the framework for
consumer market channels, business market channels are structured with the manufacturer at the top level and the
business customer at the bottom. Instead of wholesalers, jobbers, and retailers, business markets use manufacturer's
representatives, manufacturer's sales branches, and industrial distributors to distribute products.
Industrial distributors collect components from many manufacturers and resell them to business customers in
contrast to distributors for consumer markets who generally only sell goods to retailers, which resell the goods to
consumers.
Manufacturer's representatives provide consulting services to assist in the sales of industrial products, which are
often complex and benefit from the technical expertise a manufacturer's representative brings. Manufacturer's
representatives often specialize in particular areas, such as commercial lighting.
The manufacturer's sales branch facilitates sales through an indexed catalog of products and coordinates sales.
