Intermediaries in a marketing channel perform the function of sorting goods. The sorting function undertaken by intermediaries covers the functions of sorting, accumulation, allocation, and assorting. Sorting means breaking down a heterogeneous supply into separate stocks that are relatively homogeneous. Accumulation refers to bringing together similar inventory from a number of sources into a larger homogeneous supply. Allocation accounts for breaking down a homogeneous supply into smaller lots. Assorting stands for building up of an assortment of products for reselling in association with each other.
