An auditor is a person or a firm appointed by a company to execute an audit. To act as an auditor, a person should be certified by the regulatory authority of accounting and auditing or possess certain specified qualifications. Generally, to act as an external auditor of the company, a person should have a certificate of practice from the regulatory authority.
In other words, he or she is a person authorized to review and verify the accuracy of financial records and ensure that companies comply with tax laws. They protect businesses from fraud, point out discrepancies in accounting methods and, on occasion, work on a consultancy basis, helping organizations to spot ways to boost operational efficiency. Auditors work in various capacities within different industries.[1]
