Wholesalers act as intermediaries between manufacturers and retailers. By purchasing goods in bulk from producers and distributing them in smaller quantities to retailers, they play a critical role in stabilizing the supply chain, ensuring that market demand is met efficiently without manufacturers needing to deal with numerous individual retail outlets.

In standard retail documentation processes, an access slip or similar transaction document is generated in multiple copies. The retailer retains the second copy to maintain a record of the transaction for inventory control, sales tracking, and accounting purposes, ensuring that the movement of goods is properly documented at the point of sale.

Market traders are retailers who typically operate in periodic markets, such as weekly or monthly bazaars. They set up their stalls on fixed days in specific locations to serve local communities, distinguishing them from permanent shopkeepers or mobile hawkers who move constantly.

Retailers act as intermediaries in the supply chain, connecting manufacturers or wholesalers to the final consumers. Because they facilitate the flow of goods from the producer to the end-user, they are classified as middlemen. They provide value by breaking bulk, providing convenience, and offering a variety of products in one location.

Market traders often seek to minimize costs by bypassing intermediaries. By purchasing directly from manufacturers, they can secure goods at the lowest possible price, which allows for better profit margins when selling to the final consumer in a market setting.

Retailers often bear the administrative burden in hire purchase agreements because they manage the direct customer relationship, credit checks, installment collection, and the tracking of goods until the final payment is made, which requires significant ongoing documentation and follow-up.

In the context of mail-order businesses, agents often serve as intermediaries who facilitate the promotion and distribution of products to potential customers. These representatives help bridge the gap between the company and the consumer, particularly in markets where direct mail or catalog distribution requires local coordination or personal outreach to generate sales and manage customer inquiries.

In large-scale retail environments like department stores or supermarkets, the organizational structure is complex. Customers interact with sales staff or floor personnel, but they rarely have direct access to the store manager, who is responsible for high-level administrative and operational oversight rather than individual customer transactions.

In the distribution chain, the wholesaler often bears significant risk because they purchase large quantities of goods from manufacturers and hold them in inventory. They face the risk of price fluctuations, obsolescence, and the possibility that retailers may not purchase the stock. While all parties face risk, the wholesaler's role as a bulk holder makes them a primary risk-bearer in the movement of goods.

In many local agricultural economies, wholesalers act as primary intermediaries who collect produce directly from farmers. By aggregating goods from multiple small-scale producers, these wholesalers can achieve the volume necessary to supply larger markets or retailers. While wholesalers often buy from manufacturers, the specific context of 'local' trade frequently involves direct procurement from primary producers like farmers.
