Business refers to the process of being involved in both commerce and trade to earn a profit. It involves the selling of goods, services, or information by one person to other people and is usually found in capitalist countries. Trade is a subset of business that involves buying and selling and in which one purchases goods or services from another person and pays for them. Business includes not only trade but also commerce, which refers to other activities involved in business, including advertising, purchasing, operations, finance, and so on. In other words, business is the entire enterprise of making, selling, and controlling the production of goods, while trade, a narrower activity, involves only the buying and selling of goods. Trade is a part of business, but business is not the same as trade.
