Discuss and provide examples of how analytical procedures are used as substantive procedures


In the intricate world of auditing, analytical procedures are invaluable tools for auditors, particularly when employed as substantive procedures. These procedures involve evaluating financial information by studying plausible relationships among both financial and non-financial data. As substantive procedures, they are used to identify material misstatements in the financial statements. This article delves into the role of analytical procedures in substantive auditing, providing concrete examples of their application and discussing the nuances that make them a critical component of the audit process.

Understanding Analytical Procedures as Substantive Procedures:

Analytical procedures as substantive procedures involve more than just a preliminary review of financial statements; they are used to draw conclusions based on the analysis of trends, ratios, and relationships within the financial data. These procedures are particularly useful in identifying areas that may need further investigation and in providing evidence of the validity of certain financial records and assertions.

Role in Substantive Auditing:

In substantive auditing, analytical procedures are employed to verify the accuracy and completeness of the financial statements. They are especially beneficial in areas where high volumes of transactions occur or where data can be predictably correlated. These procedures can enhance the efficiency of the audit by focusing attention on areas with greater risks of material misstatement.

Examples of Analytical Procedures in Substantive Auditing:

Trend Analysis:

This involves comparing current financial data with data from previous periods to identify significant fluctuations. For example, an auditor might analyze a company’s sales revenues over the past five years. A sudden and unexplained increase or decrease in revenue could indicate errors or irregularities requiring further investigation.

Ratio Analysis:

This entails computing and analyzing financial ratios and comparing them with industry averages or internal benchmarks. For instance, an auditor may examine the current ratio (current assets divided by current liabilities) to assess a company’s liquidity position. Ratios significantly different from industry norms may signal issues in asset quality or revenue recognition.

Vertical Analysis:

This procedure involves comparing individual components of financial statements to a key figure. An example is comparing various cost elements to total sales to detect unusual variances in the cost structure that may indicate misstatements.

Horizontal Analysis:

Here, the auditor compares line items in financial statements across multiple periods. For example, a consistent increase in inventory levels without a corresponding increase in sales could raise concerns about inventory obsolescence or overstatement.

Regression Analysis:

This more advanced technique involves statistical methods to predict the value of a variable based on the value of another variable. For example, an auditor might use regression analysis to predict sales based on historical patterns and external economic indicators.

Challenges and Considerations:

Quality of Data:

The effectiveness of analytical procedures depends heavily on the quality and reliability of the data used.

Understanding of Business and Industry:

Effective analysis requires a deep understanding of the client’s business operations, industry trends, and economic environment.

Professional Judgment:

Auditors must exercise professional judgment in selecting appropriate procedures, interpreting the results, and deciding on subsequent audit actions.

Addressing the Challenges:

Thorough Planning:

This involves understanding the client’s business and industry and identifying areas where analytical procedures would be most effective.

Use of Technology:

Advanced software tools can assist in conducting sophisticated analyses like regression or variance analysis.

Integration with Other Audit Procedures:

Analytical procedures should be integrated with other substantive and control testing procedures for a comprehensive audit approach.


Analytical procedures, when used as substantive procedures, provide auditors with a powerful tool to identify potential misstatements in financial statements. These procedures, through the analysis of financial trends, ratios, and relationships, offer a perspective that is both broad and insightful. However, their effectiveness hinges on the auditor’s ability to combine technical skill with a deep understanding of the client’s business and industry. In the constantly evolving field of auditing, the adept use of analytical procedures in substantive auditing remains a key driver in achieving audit accuracy and efficiency.
