Business may be understood as the organized efforts of enterprises to supply consumers with goods and services for a profit. Businesses vary in size, as measured by the number of employees or by sales volume. Across continents, large organizations such as Steel Authority of India Limited (SAIL) and Tata Steel count their employees in hundred thousand and their sales revenues in thousands of crores. But most business units in our country are small units - independently owned and managed and employing fewer than twenty employees each. Business includes every occupation which enables people to earn/ get income through production, purchases, sales or exchange of goods and services to fulfill needs of other people.All businesses aim at making a profit. However, satisfaction of human needs is equally important.
