From business point of view, consumer protection is important because of the following reasons:
(a) Long-term interest of business. Without getting goods of the right quality, quantity and price, how can a customer be satisfied. And without satisfying customers, no business can survive for long. The customer is the foundation of any business and keeps it in existence.
(b) Business uses society's resources. Business organisations use the resources which belong to the society, thus, they have a responsibility to provide such goods and services which are in public interest. Businessman are merely trustees of resources. They must use these resources for the sake of consumers.
(c) Social responsibilities. A business organisation has many social responsibilities towards various interest groups and customer is one of the important group. So, it is the prime responsibility of a business to provide goods and services at a fair and reasonable price along with good quality. The interest of customers should be well taken care of by the business as it does with, shareholders or shakeholder.
(d) Moral justification. It is the moral duty of any business to take care of consumer's interest. It should avoid all forms of exploitation of consumers like defective and unsafe products, adulteration, false and misleading information, black marketing etc.
(e) Government intervention. Business organisations should not involved in any unfair trade practices and interests of consumers should be taken care of, then there is no need of intervention by the government because Government intervention spoils the image of the business organisation.
