Auditor: What It Is, 4 Types, and Qualifications

What Is an Auditor?

An auditor 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.

Understanding an Auditor

Auditors assess financial operations and ensure that organizations are run efficiently. They are tasked with tracking cash flow from beginning to end and verifying that an organization’s funds are properly accounted for.

In the case of public companies, the main duty of an auditor is to determine whether financial statements follow generally accepted accounting principles (GAAP). To meet this requirement, auditors inspect accounting data, financial records, and operational aspects of a business and take detailed notes on each step of the process, known as an audit trail.

Once complete, the auditor’s findings are presented in a report that appears as a preface in financial statements. Separate, private reports may also be issued to company management and regulatory authorities as well.

The Securities and Exchange Commission (SEC) demands that the books of all public companies are regularly examined by external, independent auditors, in compliance with official auditing procedures. Official procedures are established by the International Auditing and Assurance Standards Board (IAASB), a committee of the International Federation of Accountants (IFAC).

Unqualified Opinion vs. Qualified Opinion

Auditor reports are usually accompanied by an unqualified opinion. These statements confirm that the company’s financial statements conform to GAAP, without providing judgment or an interpretation.

When an auditor is unable to give an unqualified opinion, they will issue a qualified opinion, a statement suggesting that the information provided is limited in scope and/or the company being audited has not maintained GAAP accounting principles.

Auditors assure potential investors that a company’s finances are in order and accurate, as well as provide a clear picture of a company’s worth to help investors make informed decisions.

Types of Auditors

• Internal auditors are hired by organizations to provide in-house, independent, and objective evaluations of financial and operational business activities, including corporate governance. They report their findings, including tips on how to better run the business, back to senior management.
• External auditors usually work in conjunction with government agencies. They are tasked with providing an objective, public opinion concerning the organization’s financial statements and whether they fairly and accurately represent the organization’s financial position.
• Government auditors maintain and examine records of government agencies and of private businesses or individuals performing activities subject to government regulations or taxation. Auditors employed through the government ensure revenues are received and spent according to laws and regulations. They detect embezzlement and fraud, analyze agency accounting controls, and evaluate risk management.
• Forensic auditors specialize in crime and are used by law enforcement organizations.

Auditor Qualifications

External auditors working for public accounting firms require a Certified Public Accountant (CPA) license, a professional certification awarded by the American Institute of Certified Public Accountants. In addition to this certification, these auditors also need to obtain state CPA certification. Requirements vary, although most states do demand a CPA designation and two years of professional work experience in public accounting.

Qualifications for internal auditors are less rigorous. Internal auditors are encouraged to get CPA accreditation, although it is not always mandatory. Instead, a bachelor’s degree in subjects such as finance and other business disciplines, together with appropriate experience and skills, are often acceptable.

Special Considerations

Auditors are not responsible for transactions that occur after the date of their reports. Moreover, they are not necessarily required to detect all instances of fraud or financial misrepresentation; that responsibility primarily lies with an organization’s management team.

Audits are mainly designed to determine whether a company’s financial statements are “reasonably stated.” In other words, this means that audits do not always cover enough ground to identify cases of fraud. In short, a clean audit offers no guarantee that an organization’s accounting is completely above board.
