Substantive Tests of Transactions
Substantive tests of transactions are audit procedures designed to detect material misstatements directly in the financial statements. These tests focus on the details of individual transactions and are performed to gather sufficient appropriate audit evidence.
Audit Evidence
Audit evidence is the information used by the auditor to draw conclusions on the financial statements. It includes both documentary evidence (e.g., invoices, contracts) and corroborative evidence (e.g., confirmations from third parties).
Example: An auditor may review sales invoices and shipping documents to verify that revenue transactions are recorded accurately and completely.
Audit Procedures
Audit procedures are the specific actions taken by the auditor to gather evidence and evaluate the assertions made in the financial statements. These procedures can include tests of details, analytical procedures, and inquiries.
Example: The auditor may perform a test of details by selecting a sample of sales transactions and tracing them to the general ledger to ensure they are recorded correctly.
Sampling
Sampling involves selecting a subset of items from a population to test. The auditor uses statistical or non-statistical sampling techniques to determine the sample size and selection method.
Example: An auditor may use statistical sampling to select a random sample of purchase orders to test for compliance with the company's procurement policies.
Assertions
Assertions are the implicit or explicit representations made by management about the financial statements. These include assertions about existence, completeness, accuracy, valuation, and presentation.
Example: Management asserts that all sales transactions have been recorded in the correct period. The auditor tests this assertion by performing substantive tests of transactions.
Materiality
Materiality is the concept that determines the significance of an item in the financial statements. Items that could influence the decisions of users are considered material and require more attention during the audit.
Example: If a company's revenue is $10 million, an error of $100,000 in revenue would be considered material and would require correction and disclosure in the financial statements.
Examples and Analogies
Consider substantive tests of transactions as "quality control checks" in a manufacturing process. Just as quality control checks ensure that each product meets standards, substantive tests ensure that each transaction is recorded accurately.
Audit evidence is like "pieces of a puzzle," where each piece (evidence) helps the auditor form a complete picture of the financial statements. Sampling is akin to "spot-checking" in a warehouse to ensure the quality of the entire inventory.
Assertions are like "promises" made by management about the financial statements. The auditor's role is to verify these promises through substantive tests. Materiality is like "critical thresholds" in a safety system, where exceeding these thresholds requires immediate attention.
