Accounting is the system a company uses to measure its financial performance by noting and classifying all the transactions like sales, purchases, assets, and liabilities in a manner that adheres to certain accepted standard formats. It helps to evaluate a Company’s past performance, present condition, and future prospects. The theory of accounting has, therefore, developed the concept of a "true and fair view". The true and fair view is applied in ensuring and assessing whether accounts do indeed portray accurately the business' activities.

To support the application of the "true and fair view", accounting has adopted certain concepts and conventions which help to ensure that accounting information is presented accurately and consistently. Accounting concepts and conventions as used in accountancy are the rules and guidelines by that the accountant lives. All formal accounting statements should be created, preserved and presented according to the concepts and conventions that follow.
