Further, preparing the document works as a guide to the assistant auditor to summarize the work done by them.

Audit Working Papers are also essential for audit quality control purposes. The document reflects the substantial work carried out in the audit process and further works as proof of the tasks performed. In this regard, the audit working paper also demonstrates the depth to which the audit was conducted in the audit process by the auditor. The document clearly demonstrates the completeness of the audit.

Drawing Conclusions

Working papers are essential for concluding the audit findings obtained during the course of time. Such findings further help in providing useful recommendations based on the drawn claims or findings.  It is also useful for providing assurances pertaining to the quality standards that were followed in the audit process. Not just that the document also helps suggest possible areas of improvement that can be worked on for the future.

Preparing Audit Report

The auditor prepares and finalizes the audit report post conducting an audit process. The reports drafted would be based on the findings and other relevant details or information contained in the working papers. The working paper helps the auditor prepare the report without any hassle or waste of time. 

Document Evidence

 Working audits are valuable documentary evidence in the Court of law in case of a charge levied on the auditor for negligence. These documents work as evidence of the task performed by the auditor during the course of the audit. In the case of certain questionable claims put forth by the auditor, the document substantiates such claims. In this regard, the Audit Working Papers draw a clear connection and logic to the claims made by the auditor.

Permanent Record

Retention of records and evidence is crucial to any audit process and an integral part of an audit report. This is in particular essential because it helps the auditors conduct the audit effectively the next year considering this document. The previous year’s working papers are really helpful for planning and conducting the current year’s audit. Further, it also facilitates easy transition in case of a new auditor auditing in the current year. This helps in the understanding of the dynamics of the company. That said, the working papers are permanent, documented records of the work performed by the auditor that can be referred to for future audit purposes. 


Audit Working Papers are a very important part of an audit process. These documents facilitate a quick run-through after the audit process for drawing relevant conclusions and recommendations. Also, given the fact that audit is a time-consuming process, taking several days or months, it may be difficult for auditors to keep a track of it till the end of the audit program. But, with these documents in hand, it can help the auditors run through the procedure quickly and relatively easily.

Moreover, since it provides evidence to all the findings the document should be drafted sufficiently detailed and complete so that even if a new auditor comes on board can understand the kind of audit and work performed, the findings, recommendations, and conclusions reached for planning the future course of action.
