Antidote to Common Audit Documentation Deficiencies

If the audit documentation is incomplete, inaccurate, or untimely, the auditor may not be able to support their opinion, which could lead to an audit failure.

What is audit documentation, anyway?

Audit documentation is the record of the procedures performed, evidence obtained, and conclusions reached as part of an audit. It is the principal record of the auditor’s work and provides support for the auditor’s opinion in the audit report. Audit documentation is important for a number of reasons, including:

  • To provide a record of the audit work performed, which can be used to support the auditor’s opinion in the audit report.
  • To facilitate the planning, performance, and supervision of the audit engagement.
  • To provide a basis for the review of the quality of the audit work.
  • To provide a record of the auditor’s findings and recommendations, which can be used by the client to improve its internal controls and financial reporting.
  • To provide evidence that the auditor has complied with auditing standards and professional ethics.

Audit documentation can be in paper form or electronic form. It may include a variety of documents, such as:

  • Audit plans and programs
  • Checklists
  • Confirmation letters
  • Memoranda and correspondence
  • Analytical procedures
  • Summaries of significant findings
  • Copies of supporting documents, such as invoices, contracts, and bank statements

The quantity, type, and content of audit documentation are matters of the auditor’s professional judgment. However, the documentation should be sufficient to support the auditor’s opinion and to provide a record of the audit work performed.

Audit documentation is typically retained by the auditor for a period of time after the audit is complete. The retention period will vary depending on the auditor’s firm policies and the applicable laws and regulations.

I didn’t document my audit procedure properly. So, what?

Bad audit documentation can have a number of negative impacts, including:

  • Increased risk of audit failure. Audit documentation is the principal record of the auditor’s work and provides support for the auditor’s opinion in the audit report. If the documentation is incomplete, inaccurate, or untimely, the auditor may not be able to support their opinion, which could lead to an audit failure.
  • Increased risk of litigation. If audit documentation is not adequate, the auditor may be more likely to be sued by investors or other stakeholders if the client’s financial statements are found to be fraudulent or otherwise inaccurate.
  • Increased regulatory scrutiny. If an auditor’s audit documentation is found to be deficient, it could lead to increased scrutiny from regulatory bodies, such as the Public Company Accounting Oversight Board (PCAOB).
  • Damage to the auditor’s reputation. Bad audit documentation can damage the auditor’s reputation and make it more difficult to attract and retain clients.
  • Increased costs. If an auditor has to go back and fix bad audit documentation, it will increase the cost of the audit for the client.

In addition to the above impacts, bad audit documentation can also make it difficult for the auditor to identify and prevent fraud and other financial irregularities. It can also make it difficult for the auditor to assess the effectiveness of the client’s internal controls.

For all of these reasons, it is important for auditors to ensure that their audit documentation is complete, accurate, timely, and objective.
