Businesses, regulators, stakeholders and investors rely on auditors for verification of whether or not the financial statements actually reflect financial health of a company. To attain this auditors follow a well-structured method called audit procedures. Within these procedures, there is an important component known as substantive procedures.

Even if they sound same, they serve varied purposes and play different roles in the whole audit process. A proper understanding between these two assists in helping businesses to prepare better for audits and facilitates auditing students and professionals in strengthening the conceptual clarity.

What are Audit Procedures?

Audit Procedures

Audit procedures are steps and methods that auditors make use of for gathering proofs and determine whether financial statements are free from material misstatements. They support audit right from planning to conclusion.

  • Testing controls: These tests do evaluations of the quality and efficiency of the internal records. Strong internal controls decreases the chance of errors and frauds. Some of the instances are reviewing approval procedures, seeing segregation of duties, tracking system access restriction and scrutinizing reconciliations.
  • Substantive procedures: These tests do scrutinization of the accuracy, validity and completeness of the financial data. Dissimilar to controls testing, that focuses on the system, substantive procedures mainly targets the numbers and disclosures in the financial statements.

About Substantive Procedures

Substantive procedures are specified audit methods that are used for verification of the actual figures, disclosures and the amounts presented in the financial statements. They are important for detecting material misstatement caused by fraud or error.

Auditors find trends, fluctuations and patterns that might signal misstatements. Like for instance, doing comparison of existing sales to prior years, reviewing gross profit trends, doing analysis of ratios and checking if the costs aligns with business activity.

Substantive procedures focuses only on verification of financial statement accuracy. They are narrow but are more in detail and they directly address the chance of misstatements. When audit procedures are complete audit strategy, substantive procedures are the target tools utilized for validating numbers.

In simple terms, audit procedures are procedures that assists auditors in understanding how the business operates, but substantive procedures gives confirmation of what all financial statements shows.
