The use of intermediaries is the primary difference between the two.
Step-by-step explanation:
Direct distribution channel is one in which the consumer is directly connected to the manufacturer and there is no use of a distribution system that is separate from them and there are no intermediaries.
The contact between the two is direct.
To the contrary in an indirect distribution channel there is no direct connection between the manufacturer and the person who is actually buying the product and the business is being mediated by the middlemen.
