The Financial Accounting Standards Board (FASB), American Institute of Certified Public Accountants (AICPA), Securities and Exchange Commission (SEC), and the International Accounting Standards Board (IASB) work together to create new and amend older standards in order to establish and maintain a common language for communicating financial information.
These organizations set accounting, auditing, and other standards and are excellent starting points when searching for accepted practices and procedures in accounting and auditing.
