Indirect exchange is a two step exchange in which the first step is to exchange one's goods or services for a medium of exchange, usually money, and the second step is to exchange the medium of exchange so obtained for the goods or services desired. Indirect exchange contrasts with direct exchange, i.e., barter or trucking, in which one trades his goods or services directly for the desired goods or services of another without the intermediary use of a medium of exchange, usually money. The need for indirect exchange increases as the division of labor increases and more goods and services become available for exchange.
