/What is Tracing in Auditing?
Tracing is the process of following a transaction in the accounting records back to the source document. This typically involves locating an item in the general ledger, tracing it back to a subsidiary ledger (if necessary) to look for the unique identifying document number, and then going to the accounting files to locate the source document. Tracing is used to track down transactional errors, and also by auditors to verify that transactions were recorded properly. Auditors use tracing on a sampling basis, where the results obtained are assumed to apply to the entire population of transactions.
Example of Tracing
An auditor for Grumpy & Sons is reviewing the purchases made by a client. She makes a random selection of the purchases recorded by the client, and reviews the purchase order authorization for each one, as well as the associated receiving record and supplier invoice. Her intent is to trace the purchased amount stated in the client’s general ledger back to the amount billed by the supplier. She uses the purchase order review to determine whether the purchase was authorized, and examines the receiving record to verify that the associated goods were received.

Advantages of Using Tracing in Auditing
The key advantages of using tracing in auditing are as follows:
Ensures completeness. Tracing helps verify that all transactions originating in source documents are recorded in the accounting system and included in the financial statements.
Detects errors or omissions. By tracing transactions step-by-step, auditors can identify where errors or omissions might have occurred in the recording process.
Strengthens internal control evaluation. Tracing provides insights into the effectiveness of internal controls related to transaction processing.
Improves audit trail validation. Tracing ensures there is a clear and reliable audit trail from source documents to the final financial statements.
Supports assertions testing. Tracing is particularly useful for testing the completeness assertion, ensuring that no material transactions are excluded from the financial records.
Increases audit confidence. By methodically following a transaction, auditors gain confidence that financial records are complete and accurate. It also reduces the risk of material misstatements, enhancing the overall reliability of the audit opinion.
Tailored for specific risks. Tracing can be focused on high-risk areas where there is a higher likelihood of errors or fraud.
Useful for fraud detection. Tracing can help detect fraud by identifying transactions that appear to be missing or improperly recorded at certain stages.
In summary, tracing is a powerful tool for ensuring that transactions are completely and accurately captured in financial statements, making it an essential part of an auditor’s substantive procedures and risk assessment.
