Commerce is the exchange of goods and services among two or more parties which often requires their transportation from one place to another (between cities, countries or between parts of a country), especially on a large scale.[1] More specifically, commerce is not business, but rather the part of business which englobes all activities, functions and institutions related to the movement and distribution of finished or unfinished goods and services from the producers to the consumers on a large scale, as opposed to the sourcing of raw materials and manufacturing of those goods. Commerce is subtly different from trade as well, which is the final transaction, exchange or transfer of finished goods and services between a seller and an end consumer. Commerce not only includes trade as defined above, but also a series of transactions that happen between the producer and the seller with the help of the auxiliary services and means which facilitate such trade. These auxiliary services include transportation, communication, warehousing, insurance, banking, financial markets, advertising, packaging, the services of commercial agents and agencies, etc. In other words, commerce encompasses a wide array of political, economical, technological, logistical, legal, regulatory, social and cultural aspects of trade on a large scale. From a marketing perspective, commerce creates time and place utility by making goods and services available to the customers at the right place and at the right time by changing their location or placement. Described in this manner, trade is a part of commerce and commerce is a part of business.

Commerce was a costly endeavor in the antiquities because of the risky nature of transportation, which restricted it to local markets. Commerce then expanded along with the improvement of transportation systems over time. In the middle ages, long-distance and large-scale commerce was still limited within continents. With the advent of the age of exploration and oceangoing ships, commerce took an international, trans-continental stature. Currently the reliability of international trans-oceanic shipping and mailing systems and the facility of the Internet has made commerce possible between cities, regions and countries situated anywhere in the world. In the 21st century, Internet-based electronic commerce (where financial information is transferred over Internet), and its subcategories such as wireless mobile commerce and social network-based social commerce have been and continue to get adopted widely.
