What is an audit?

An audit is an independent or internal examination of a company’s financial statements, operations, processes, or systems to assess their accuracy, compliance, and potential risks. Depending on its purpose, an audit may cover financial records, internal controls, compliance procedures, IT systems, or specific business activities.

Audits are used to verify the reliability of information, identify errors and weaknesses, and evaluate whether a business follows applicable requirements and internal standards. The exact scope, mandatory status, and format of an audit depend on the jurisdiction, company size, industry, and purpose of the review.

Audit definition

An audit is a systematic examination of financial information, internal processes, controls, or specific areas of a company’s activities. The purpose of an audit is to determine whether information is accurate, processes are reliable, and operations comply with applicable requirements.

An audit may include:

1. Financial audit – review of financial statements;
2. Internal audit – assessment of internal processes and controls;
3. Compliance audit – review of compliance with laws, licences, and internal policies;
4. IT audit – assessment of information systems and technology risks;
5. Operational audit – review of business process efficiency.

In simple terms

An audit helps determine whether a company’s actual operations match its reporting, rules, and internal procedures. It can identify errors, weak controls, and risks before they develop into more serious problems.

How does an audit work?

An audit usually begins by defining its purpose, scope, and the criteria used to assess the company. The auditor then collects documents, reviews processes, and tests selected controls to determine how they operate in practice.

An audit usually includes the following stages:

1. Define the scope. The company identifies which financial information, processes, systems, or compliance areas will be reviewed.
2. Collect information. The auditor requests documents, reports, policies, agreements, and other supporting materials.
3. Review and test. Transactions, internal controls, and compliance with relevant requirements are examined.
4. Identify issues. Errors, weaknesses, non-compliance, and potential risks are documented.
5. Prepare the findings. The audit results are summarized in a report, often with recommendations where appropriate.

The depth of an audit depends on its type. A financial audit, compliance audit, and IT audit may use different methods, but each is designed to provide an objective assessment of the area being reviewed.

Why is an audit important?

An audit is important because it helps a company understand whether its financial, operational, and compliance processes are working reliably. An independent or internal review can identify errors, weak controls, and non-compliance before they lead to financial losses, regulatory action, or reporting problems.

An audit is particularly useful for:

• Confirming the reliability of financial information;
• Assessing the effectiveness of internal controls;
• Identifying compliance gaps;
• Preparing for investment, M&A, or due diligence;
• Reviewing compliance with licences and regulatory requirements;
• Improving internal processes and risk management.

For regulated businesses, an audit may be more than a best practice and can be a mandatory requirement. The exact frequency and format depend on the jurisdiction, industry, and regulatory status of the company.

Audit for business and legal compliance

For businesses, an audit helps assess whether internal processes comply with applicable law, regulatory requirements, and the company’s own policies. This is particularly important for fintech, crypto, financial services, and other regulated industries, where weak controls can affect licensing, banking relationships, and interactions with regulators.

In practice, an audit may cover AML/KYC procedures, transaction monitoring, internal governance, reporting, data protection, outsourcing, and other compliance areas.

Examples of audit

An audit can cover different areas of a company’s operations depending on the purpose of the review.

Example 1. Financial audit

A company undergoes a review of its financial statements before attracting an investor. The auditor examines accounting records, key transactions, and supporting documents to assess the reliability of the reported information.

Example 2. Compliance audit

A crypto business reviews whether its AML/KYC procedures, transaction monitoring, and reporting comply with internal policies and applicable regulatory requirements.

Example 3. IT audit

A fintech company conducts an audit of its information systems to assess access controls, data security, and the resilience of key infrastructure.

Audit vs Due Diligence

An audit and due diligence may both involve reviewing documents, financial information, and internal processes, but they serve different purposes.

An audit generally answers whether a specific area of the business is accurate, compliant, and properly controlled. Due diligence is used to understand potential risks before an investment, acquisition, or other significant transaction.
