Commerce is the organized system of activities, functions, procedures and institutions that directly or indirectly contribute to the smooth, unhindered large-scale exchange of goods, services, and other things of value—predominantly through transactional processes—at a specified time, place, quantity, quality and price through various channels among the original producers and the final consumers within local, regional, national or international economies. The diversity in the distribution of natural resources, differences of human needs and wants, and division of labour along with comparative advantage are the principal factors that give rise to commercial exchanges.
