While a trial balance is a useful tool for detecting many types of errors in the accounting records, there are certain errors that may not be revealed by the trial balance alone. [Copyright (c) Notes by Sachin Arora]
Some examples of errors that may not be detected by the trial balance include:
- Errors of Omission: If a transaction is completely omitted from the accounting records, it won’t be reflected in the trial balance. [Copyright (c) Notes by Sachin Arora]
- Compensating Errors: When two errors offset each other in a way that the trial balance still balances despite the mistakes.
- Errors of Principle: Misclassifying an item as an expense when it should be a capital expenditure, or vice versa.
- Errors of Commission: Incorrectly recording a transaction, such as entering the wrong amount or using the wrong account. [Copyright (c) Notes by Sachin Arora]
- Errors in Original Entry: Making mistakes when initially recording a transaction.
- Errors in Reversal of Entries: Accidentally reversing debit and credit entries.
- Errors in Posting: Posting a transaction to the wrong account.

To detect these errors and ensure the accuracy of financial statements, auditors take various steps, including:
- Vouching: Auditors trace transactions from the financial statements back to the original source documents to verify their accuracy. [Copyright (c) Notes by Sachin Arora]
- Reperformance: Auditors independently perform calculations and procedures to confirm the accuracy of recorded transactions.
- Analytical Procedures: Auditors compare financial data to industry averages, prior periods, or other benchmarks to identify unusual patterns or trends.
- Physical Inspection: Physically inspecting assets to ensure they exist and are accurately recorded.
- Confirmation: Auditors may send confirmation requests to external parties (e.g., customers, suppliers) to verify the accuracy of account balances. [Copyright (c) Notes by Sachin Arora]
- Scanning: A quick review of the entire set of financial statements to identify any obvious errors or inconsistencies.
- Substantive Testing: Detailed testing of individual transactions and account balances to provide assurance on the accuracy of financial information. [Copyright (c) Notes by Sachin Arora]
