Domestic trade, also known as internal trade or home trade, is the exchange of domestic goods within the boundaries of a country. This may be sub-divided into two categories, wholesale and retail. Wholesale trade is concerned with buying goods from manufacturers or dealers or producers in large quantities and selling them in smaller quantities to others who may be retailers or even consumers. Wholesale trade is undertaken by wholesale merchants or wholesale commission agents.
Retail trade is concerned with the sale of goods in small quantities to consumers. This type of trade is taken care of by retailers. In actual practice, however, manufacturers and wholesalers may also undertake retail distribution of goods to bypass the intermediary retailer, by which they earn higher profits.
