To have a clear idea of the important rules of accounting finance we must define the word financial accounting first. So we simply relate financial accounting to the preparation of financial statements for its users such as creditors, suppliers and investors.

No one can deny the importance of accounting in any kind of business. To run an organization one must know how accounting helps in business. As the techniques of marketing changed the accounting standards also have evolved over time to the system of rules that also exist today.

Since accounting had become customary in all kind of business. In 1973, the Financial Accounting Standards Board (FASB) was established. In order to evaluate and analyze the problems which are brought to their attention in the field of accounting. The process of evaluating these problems is long and tedious but necessary to the maintenance of the standard rules for accounting finance. FASB highlights the importance of getting in touch with accountants so they concentrate on their resources to reach and eradicate the problems that are faced by accountants.

Since FASB is not a government agency so they need someone to help them financially so for that very reason it is financed on a private basis. One of the financial supporters of FASB is the American Institute of Certified Public Accountants.

FASB has established a code for financial statements preparation which is called the Generally Accepted Accounting Principles (GAAP). Countries other than the United States have their own principles which are comparable to GAAP and FASB, and globally, all types of principles defines different approaches for countries that are to be implemented in future.

The crux of those principles like GAAP is to inform the users of the financial statements that how effective is their financial statement is, and to provide a guideline for best results.
