An auditor is a person or a firm appointed by a company to execute an audit. [1] 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.
For publicly traded companies, external auditors may also be required to express an opinion over the effectiveness of internal controls over financial reporting. External auditors may also be engaged to perform other agreed-upon procedures, related or unrelated to financial statements. Most importantly, external auditors, though engaged and paid by the company being audited, should be regarded as independent.
The internationally recognised standard setting body for the profession is the Institute of Internal Auditors - IIA (www.theiia.org). The IIA has defined internal auditing as follows: "Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes". [2]

An audit is an "independent examination of financial information of any entity, whether profit oriented or not, irrespective of its size or legal form when such an examination is conducted with a view to express an opinion thereon." Auditing also attempts to ensure that the books of accounts are properly maintained by the concern as required by law. Auditors consider the propositions before them, obtain evidence, roll forward prior year working papers, and evaluate the propositions in their auditing report.
A financial audit is conducted to provide an opinion whether "financial statements" are stated in accordance with specified criteria. Normally, the criteria are international accounting standards, although auditors may conduct audits of financial statements prepared using the cash basis or some other basis of accounting appropriate for the organization. In providing an opinion whether financial statements are fairly stated in accordance with accounting standards, the auditor gathers evidence to determine whether the statements contain material errors or other misstatements.

Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control and governance processes.

With commitment to integrity and accountability, internal auditing provides value to governing bodies and senior management as an objective source of independent advice. Professionals called internal auditors are employed by organizations to perform the internal auditing activity.
