Understanding Internal vs. External Audits: A Guide for SME Owners in Singapore

Audits are critical tools for evaluating a company’s financial health and operational efficiency. For small and medium-sized enterprises (SMEs) in Singapore, understanding the difference between internal and external audits is essential for effective accounting services and proper financial governance. While both audits provide valuable insights, they differ in their objectives, scope, and who performs them.

In this blog, we will explore the unique characteristics of internal and external audits and discuss how they contribute to better governance, risk management, and financial integrity for SMEs in Singapore.

What is an Internal Audit?

An internal audit is an independent, objective review that assesses the effectiveness of a company’s internal processes, including its governance, risk management, and internal controls. These audits are typically conducted by internal auditors who are either part of the company’s staff or external firms hired to conduct a thorough review of operations.

Objectives of an Internal Audit:

• Risk Assessment: Identifying and addressing potential risks within the organisation.
• Internal Controls: Reviewing the efficiency and effectiveness of internal processes designed to safeguard assets.
• Compliance: Ensuring the company adheres to internal policies and regulations.
• Operational Efficiency: Evaluating whether the company’s resources are optimally utilised.

Example: An internal audit might assess whether a Singapore-based SME is complying with its data protection policies and identify gaps in the company’s cybersecurity practices.

What is an External Audit?

An external audit involves an independent evaluation of a company’s financial statements, ensuring they reflect a true and accurate picture of the company’s financial health. External auditors are typically certified professionals who are not affiliated with the company and provide an unbiased opinion on the financial records.

Objectives of an External Audit:

• Accuracy of Financial Statements: Ensuring financial statements are prepared correctly in accordance with accounting standards such as the International Financial Reporting Standards (IFRS).
• Compliance with Standards: Verifying that the company is following required legal and regulatory financial reporting practices.
• Financial Transparency: Providing stakeholders such as investors, creditors, and regulators with a reliable view of the company’s financial position.
• Detection of Misstatements: Identifying any material misstatements, whether caused by fraud or error, in the company’s financial statements.

Example: An external audit for a Singapore SME might focus on reviewing whether the company’s annual income statement and balance sheet comply with Singapore Financial Reporting Standards (SFRS).

Key Differences Between Internal and External Audits

Though both internal and external audits serve to enhance a company’s operations, they differ in their scope, objectives, and the people performing them. Let’s break down the key distinctions:

1. Purpose and Focus

• Internal Audits: Primarily focus on evaluating and improving internal processes, risk management practices, and operational efficiency.
• External Audits: Focus on providing an independent assessment of the financial statements to ensure they accurately reflect the company’s financial position.

Example: While internal auditors might examine how effectively a company manages its supplier contracts, external auditors will focus on whether the company’s financial transactions related to suppliers are accurately recorded.

2. Who Conducts the Audit?

• Internal Audits: Conducted by employees within the organisation or an outsourced team working closely with the company.
• External Audits: Performed by independent auditors or external audit firms that are not affiliated with the company, ensuring impartiality.

Example: A company may rely on its internal audit department to assess its internal controls, but an external audit will be carried out by an independent firm to examine its financial records.

3. Scope of the Audit

• Internal Audits: Cover a broad range of operational aspects, including financial reporting, internal controls, compliance, and operational effectiveness.
• External Audits: Focus mainly on the financial statements and whether they accurately reflect the company’s financial position.

Example: An internal audit may review a company’s operational efficiency, such as how well inventory is managed, while an external audit focuses on verifying whether inventory transactions are properly recorded in the financial statements.

4. Reporting Structure

• Internal Audits: Results are reported to the company’s management, board of directors, or an audit committee. The findings often include recommendations for process improvements.
• External Audits: Results are reported to external stakeholders, such as shareholders, investors, and regulators, offering an unbiased opinion on the company’s financial health.

Example: Internal auditors may present their findings to senior management, while the external audit report will be shared with external stakeholders in the company’s annual financial report.

5. Frequency of Audits

• Internal Audits: Conducted on a more frequent basis, depending on the company’s needs, emerging risks, or significant changes in operations.
• External Audits: Generally conducted annually, aligned with the company’s fiscal year-end, but can also be required quarterly or for regulatory reasons.

Example: An internal audit may take place every quarter to monitor operational risks, while an external audit is scheduled at the end of the fiscal year to review the company’s financial statements.

Why are Both Audits Important for SMEs in Singapore?

1. Strengthening Internal Controls and Risk Management

• Internal audits help identify inefficiencies and risks, offering solutions to improve processes.
• They also ensure that controls are in place to safeguard assets and mitigate potential threats.

2. Ensuring Financial Transparency and Accountability

• External audits provide an unbiased review of financial statements, ensuring accuracy and compliance with accounting standards.
• This independent verification enhances the trustworthiness of financial reports for external stakeholders.

3. Complying with Legal and Regulatory Standards

• Internal audits ensure adherence to internal policies and help SMEs stay compliant with industry regulations.
• External audits confirm compliance with national financial reporting standards, such as the Singapore Financial Reporting Standards (SFRS).

When Should SMEs Engage Internal and External Auditors?

• Internal Auditors: Engaged continuously to monitor and improve processes, manage risks, and ensure the alignment of operations with the company’s strategic objectives.
• External Auditors: Typically hired annually to audit the company’s financial statements. However, depending on regulatory requirements, SMEs may also engage external auditors quarterly or for specific needs.

Example: A Singapore SME may have internal auditors working throughout the year to assess internal processes, while an external auditor would be engaged annually to verify the company’s year-end financial statements.

Summary

For SMEs in Singapore, understanding the distinctions between internal and external audits is vital for improving business operations, managing risks, and ensuring financial transparency. While internal audits focus on operational efficiency and internal controls, external audits provide independent verification of financial statements. Together, both types of audits help SMEs comply with regulations, build trust with stakeholders, and drive long-term business success.
