3. Audit vs Review vs Compilation — Key Differences

Understanding Key Terms
Businesses often use the terms audit, review, and compilation interchangeably. However, in law and professional practice, these represent:
  • Audit: Provides the highest level of assurance
  • Review: Offers moderate assurance
  • Compilation: Involves no assurance
Each engagement carries a different level of responsibility and consequence.
This article explains how audit, review, and compilation differ, when each applies, and why choosing the wrong engagement can create serious compliance and credibility risks.



1. Introduction — Why This Distinction Matters

Financial statements may be:
  • Audited
  • Reviewed
  • Compiled
Each carries a different degree of reliability for users such as:
  • Banks
  • Investors
  • Regulators
  • Business partners
Misunderstanding these differences often leads to false confidence or regulatory non-compliance.
Impact: Treating a review or compilation as an audit is a common and costly mistake.

2. Objective of Each Engagement

The objective differs significantly across engagements:
  • Audit: To express an opinion on whether financial statements give a true and fair view
  • Review: To provide limited assurance that nothing has come to the practitioner’s attention indicating material misstatement
  • Compilation: To assist management in preparing financial statements without providing any assurance
Understanding the objective clarifies the level of reliance users can place on the financial statements.

3. Audit — Nature and Assurance Level

Nature of Engagement
An audit is a statutory or voluntary assurance engagement conducted in accordance with auditing standards.
Level of Assurance
  • Reasonable assurance
  • Highest level of confidence short of absolute certainty
Key Characteristics
  • Risk-based planning
  • Testing of transactions and balances
  • Evaluation of internal controls
  • Independent audit opinion
Typical Use Cases
  • Statutory audit under Companies Act
  • Lender or investor requirements
  • Regulatory filings

4. Review — Nature and Assurance Level

Nature of Engagement
A review is a limited assurance engagement, usually governed by review standards.
Level of Assurance
  • Limited assurance
  • Negative assurance (nothing has come to attention)
Key Characteristics
  • Primarily analytical procedures
  • Inquiry-based
  • No detailed testing of transactions
Typical Use Cases
  • Interim financials
  • Smaller entities where audit is not mandatory
  • Comfort to limited stakeholders
Impact: A review does not provide the confidence level of an audit.

5. Compilation — Nature and Assurance Level

Nature of Engagement
A compilation is a non-assurance engagement.
Level of Assurance
  • No assurance at all
Key Characteristics
  • Financial statements prepared based on management information
  • No verification or testing
  • No opinion or conclusion
Typical Use Cases
  • Internal management reporting
  • Basic financial statement preparation
  • Compliance where assurance is not required

6. Comparison — Audit vs Review vs Compilation (Conceptual)

Audit involves:
  • Verification
  • Professional judgement
  • Independent opinion
Review involves:
  • Inquiry and analytics
  • Limited conclusion
Compilation involves:
  • Presentation only
  • No verification
The responsibility shifts progressively from auditor-led assurance to management responsibility.

7. Legal & Compliance Perspective

  • Statutory audit is mandated by law for companies
  • Review or compilation cannot substitute a statutory audit
  • Submitting reviewed or compiled statements where audit is required leads to non-compliance
Wrong engagement selection can invalidate filings and attract penalties.

8. Common Misconceptions in Practice

  • “Reviewed statements are almost audited”
  • “Compilation means CA has verified numbers”
  • “Bank won’t notice the difference”
In reality, users are increasingly alert to the type of engagement performed.

9. Practical Guidance for Management

Before finalising financial statements, management should clarify:
  • What engagement is legally required?
  • What assurance do stakeholders expect?
  • What level of risk can the business accept?
Choosing the right engagement avoids future disputes.
