Usually, goods are not sold or consumed immediately after production. They are held in stock to make them available as and when required. Special arrangement must be made for storage of goods to prevent loss or damage. Warehousing helps business firms to overcome the problem of storage and facilities the availability of goods when needed. Prices are thereby maintained at a reasonable level through continuous supply of goods.

Business involves various types of risks. Factory building, machinery, furniture etc, must be protected against fire, theft and other risks. Materials and goods held in stock or in transit are subject to the risk of loss or damage. Employees are also required to be protected against the risks of accident and occupational hazards. Insurance provides protection in all such cases. On payment of a nominal premium, the amount of loss or damage and compensation for injury if any, can be recovered from the insurance company.

Nowadays we cannot think of business without bank. To start the business or to run it smoothly we require money. Banks supply money. Business activities cannot be undertaken unless funds are available for acquiring assets, purchasing raw materials and meeting other expenses. Necessary funds can be obtained from bank. Thus, banking helps business activities to overcome the problem of finance.

Manufacturing industries are engaged in producing goods through processing of raw materials and thus creating form utilities. They bring out diverse finished products, which we consume or use, through the conversion of raw materials or partly finished materials in their manufacturing operations.

Secondary industries are concerned with using the materials which have already been extracted at the primary stage. These industries process such materials to produce goods for final consumption or for further processing by other industrial units. For example mining of an iron ore is a primary industry, but manufacturing of steel by way of further processing of raw irons is a secondary industry.
