What is Audit?

An audit or audit is an inspection or examination of processes, activities and records to ensure compliance or requirements.

The biggest audit we have ever known concerns the financial audit, in which a series of accounts or business books, documents or records are inspected to determine if they are accurate and follow the rules and laws.

Auditing is required to help build trust within a company or in a specific entity that requires public trust. For companies, an internal audit helps to prevent fraud. 

The Companies Act of 2013 governs audits in India. The act makes it mandatory for all companies in India to conduct audits. Any practising chartered accountant duly registered under the Chartered Accountants Act of 1949 is eligible to be appointed as a company auditor as per Section 141 of the Companies Act for 2013.

Types of Audit

There are mainly nine types of audits –

1. Internal audit – Internal audits are conducted by an organization’s internal audit department or professionals to evaluate and improve the effectiveness of internal controls, risk management processes, and operational efficiency.
2. External audit – An external entity performs the eternal audit and objectively assesses an organization’s financial statements.
3. Financial audit – In a financial audit, a third-party auditor is commonly hired to perform a financial audit on a company to ensure the accuracy of the company’s financial records and statements. 
4. Operational Audit: Operational audits evaluate the efficiency and effectiveness of an organization’s operations, processes, and systems. 
5. Payroll audit – A payroll audit is an internal audit performed by an auditor to ensure payroll accuracy. The audit involves wages, taxes, benefit deductions, employee information, and withholdings.
6. IRS Tax Audit – Such audits are internal and ensure the accuracy of filed tax returns. IRS audits help to ensure there is no discrepancy or that the company has not paid more or fewer taxes.
7. Information Systems Audit: Information systems audits assess an organization’s information systems’ reliability, security, and integrity. 
8. Forensic Audit: Forensic audits help to investigate and uncover potential fraud, financial irregularities, or misconduct within an organization. 
9. Performance Audit: Performance audits evaluate a government agency or program’s efficiency, economy, and effectiveness. 

Features of Audit

• Objective Review: An audit is an independent examination of the financial records for accuracy and conformity with laws and regulations.
• Systematic Process: Audits are carried out in a structured, methodical way, reviewing transactions, controls, and procedures in detail.
• Compliance Focus: The primary purpose of an audit is to determine if the financial statements comply with accounting standards and regulations.
• External or Internal: Audits can be carried out by external auditors (independent of the organization) or internal auditors (employees).
• Periodic: Audits are usually conducted periodically, mostly annually, to review financial performance.
• Opinion and Report: After completing the audit, the auditors submit a written report on whether the financial records are accurate and credible.

What is an Investigation?

Investigation is a process of gathering information, examining evidence, and conducting inquiries to uncover facts, resolve specific issues, or address allegations of wrongdoing. Investigations are often triggered by suspicions, concerns, complaints, or incidents involving fraud, misconduct, policy violations, or other irregularities. 

The investigation aims to establish the truth, identify responsible parties, gather evidence for further action, and potentially support legal proceedings or disciplinary actions. The investigation has a predetermined scope and purpose and is conducted by an investigator on behalf of the person who requires the information about the company. Investigations can be conducted internally by designated personnel, external investigators, or law enforcement agencies in cases of suspected criminal activity. 

The investigative audit examines the following:

1. Planning: The audit team identifies the scope of the investigation, including specific areas, transactions, or people involved. Auditors gather relevant information and develop an investigative plan.
2. Investigation: Auditors gather evidence through interviews, document review, data analysis, and other investigative techniques. They may also consult with legal or forensic experts to aid in the investigation.
3. Analysis: The collected evidence is analyzed to establish patterns, identify irregularities, and determine the extent of potential fraud or misconduct. This analysis helps auditors understand the issues’ underlying causes and potential impact.
4. Reporting: The findings of the investigative audit are documented in a comprehensive report. The report typically includes a summary of the investigation, the identified issues, the evidence gathered, and recommendations for remedial actions or further investigations.

Features of Investigation:

• In-Depth Examination: An investigation is a more detailed, focused examination that examines specific issues like fraud, misconduct, or irregularities.
• Purpose-Specific: Investigations are often conducted to uncover problems or concerns, such as theft, corruption, or financial mismanagement.
• Ad Hoc Process: Investigations are not done regularly like audits but are typically initiated in response to specific concerns or incidents.
• Can Result in Litigation: In some cases, investigations may result in litigation or disciplinary action based on the findings.
• Confidential: Investigations are usually confidential for the integrity of the process and to avoid the interference of evidence.

Main Differences Between Audit And Investigation

Purpose

Audit: To assess and provide an independent opinion on the accuracy, reliability, and compliance of financial statements, processes, or controls. 

Investigation: To spot specific fraud, misconduct, illegal activities, or significant irregularities. The objective is to gather evidence, determine the facts, and identify responsible parties.

Scope

Audit: Broader scope and cover various aspects of an organization, such as financial statements, internal controls, operations, and compliance.  

Investigation: Investigations have a narrower scope and are focused on specific incidents or allegations. Investigators gather evidence related to a particular issue or event, such as fraud, embezzlement, or violation of company policies.

Approach

Audit: Audits follow a systematic and structured approach using predefined procedures and sampling techniques. They rely on professional judgment and generally accepted auditing standards to evaluate controls, identify risks, and verify financial information.

Investigation: Investigations are more flexible and often require a customized approach based on the nature of the issue. Investigators may employ interviews, data analysis, forensic accounting, and document review to gather evidence and uncover the truth.

Independence

Audit: Auditors, usually external, maintain independence from the audited organization to ensure objectivity and impartiality. 

Investigation: Investigators may be internal or external to the organization, depending on the circumstances. They often have a specific reporting structure, such as reporting to a special committee or legal department, to ensure independence and integrity.

Reporting

Audit: Audits result in an audit report that provides an opinion on the financial statements or other audited areas. The report communicates findings, identifies weaknesses or areas of improvement, and may include recommendations.

Investigation: Investigations culminate in a report presenting the findings, evidence, and conclusions related to the investigated issue. The report may serve as a basis for disciplinary actions, legal proceedings, or other remedial measures.
