Convention of consistency

The transaction recording methodology should not be changed at any cause or moment. It must be maintained throughout the life span of the firm. Consistency in method will provide an opportunity to compare the financial statements to get various information and interpretations from it. Therefore, the accounting rules must be carefully observed and obtain the same year after year.

For example: If a firm follows the method of straight line for charging the depreciation since its inception should be followed without any change . The firm should not alter the method of charging the depreciation from one to another.
