The purpose of audit engagement letter outlined is to prevent misunderstanding, future disputes, or errors in work operations. The auditor presents this document before the audit and engagement commencement, and formal acknowledgment occurs only after clear communication and receipt. The definition emphasizes its integral and mandatory role in the audit process, serving as widely accepted evidence between the auditor and clients in case of disputes or unclear clauses.

It elaborates on each party’s responsibilities during the audit, including additional help, resources, and services to ensure a smooth process. For every audit firm, it is crucial to establish policies on acquiring new clients and training existing ones. Many firms use a standard audit engagement letter sample, but it’s essential to note that if the auditor is not independent, it may lead to noncompliance and negative publicity.

Examples

Lets understand the concept with the help of some examples.

Example #1

Suppose a local bank requires an audit. After communication and mutual understanding between the bank and the auditor, the auditor issues an audit engagement letter to confirm the appointment formally. This comprehensive letter outlines specific responsibilities, scope, broad duties, and obligations associated with the audit, including a 90-business-day timeline and the required resources for the process.

The audit, a routine practice for many banks and financial institutions, involves a thorough review and assessment of bank statements, balance sheets, and financial reports. This process ensures transparency, identifies potential crises, and guards against malicious or fraudulent activities.

In the letter, the auditor specifies compensation details, the audit end date, and the payment method. This information facilitates smooth functioning and establishes clear expectations between the auditor and the local bank.

After 90 days, the auditor submits a comprehensive report, concluding the audit process and receiving the agreed-upon fees. While this serves as a simplified example, it’s important to note that real-world scenarios involve additional factors and considerations.

Example #2

With the implementation of Statement on Auditing Standards (SAS) 136, benefit plan sponsors are now tasked with additional duties and responsibilities. Under this new standard, plan sponsors, as outlined by the Employee Retirement Income Security Act (ERISA), must engage a qualified accountant to audit financial statements if their plans have 100 or more participants.

The audit engagement letter, a crucial component of this process, requires plan sponsors to explicitly acknowledge their responsibilities, including maintaining plan documents and ensuring accurate transactions. The added responsibilities underscore the Importance of thorough preparation for audits, ensuring compliance with the new requirements under SAS 136.
