What Is an Audit?
The term audit usually refers to the financial audit or review of financial statements. A financial audit is an objective examination and evaluation of the financial statements of an organization to make sure that the financial records are a fair and accurate representation of the transactions they claim to represent. The audit can be conducted internally by employees of the organization or externally by an outside certified public accountant (CPA) firm.
