What Do Auditors Do? Understanding an Auditor’s Responsibilities

Understanding auditor responsibilities

It is a misconception that the responsibilities of an external auditor can be summed up to individuals that examine financial records with the goal of forming an opinion about the fairness of information presented within a company’s financial statements. An audit, in a broader sense, is a method of creating an opinion or conclusion about processes, transactions, or other information when compared to a standard or criteria. There are a variety of different services or reasons a company may need to engage an auditor.

If embraced, business owners can use auditors as tools to enhance processes and procedures, create a tone from the top that deters fraudulent activity, and hold both management and employees accountable to execute their roles and responsibilities. In this post, we will review a number of topics to gain an understanding of an auditor’s responsibilities in completing an audit and the professional duties they hold as an external auditor.

 

What is the function of an auditor?

What are the Main Functions of an Auditor?

Below are examples of different audit functions, the auditor’s duties, and scope of work:

Internal Audit

An internal auditor is responsible for performing procedures that test the efficiency and effectiveness of company internal controls put in place to achieve business objectives. The scope of an internal audit includes all financial and operational controls that are used to create maximum productivity at a company. Example findings or duties include:

  • Provide recommendations to improve weak internal controls
  • Investigate instances of possible fraud (even those considered immaterial)
  • Perform reconciliations of financial and operating information
  • Monitor compliance with industry standards, laws, and guidelines
  • Evaluate whether processes and procedures are functioning properly

Forensic Audit

An auditor is responsible for using a mixture of audit and investigative techniques to determine whether the suspicion of fraud is warranted and if so, the effects of the fraud. The scope of forensic audits can be as wide as necessary and can take a significant amount of time and resources. Generally, a successful forensic audit relies greatly on the types of monitoring a company has in place. This allows a forensic auditor to utilize logs and information captured as part of monitoring to put an accurate timeline together.

Attestation Services

An external auditor is responsible for providing different services to clients such as guidance on accounting-related matters, technical disciplines, or industry knowledge. Scope of work depends on services rendered but is generally defined by an agreement between the client and auditor.

Auditors report on subject matters like the design and operating effectiveness of a service organization’s internal controls over a certain objective such as security. This is also known as System and Organization Controls (SOC) Reports. See below for more information on this type of report.

Information System Audit: Sample Attestation Service

An external auditor is responsible for evaluating the internal controls pertinent to a company’s IT infrastructure. Scope of information system audits can be determined based on a specific objective but generally include the following steps:

 

What are the responsibilities of an auditor?

What are the Duties and Responsibilities of an External Auditor?

The AICPA has defined the professional responsibilities of auditors performing attestation services. As outlined in AU Section 110, an auditor’s responsibilities when performing a financial statement audit is to create a plan and then execute that plan by collecting applicable supporting evidence to make a determination, or opinion, on whether or not the financial statements presented by management are free and clear of any material misstatements that were presented by way of error or fraudulent activity. Any errors or fraud that do not meet the threshold for materiality are not the responsibility of the auditor

For other types of attestation examinations, auditors are responsible for following SSAE 18. SSAE 18 details an auditor’s responsibilities in performing an audit, and reporting on the opinion, conclusion, or findings in accordance with the attestation standards and type of engagement. While an external auditor is responsible for making sure that the opinion, findings, or conclusion are reported in accordance with requirements, the ultimate responsibility of the subject matter itself is still the responsibility of the client. Let’s talk a little more about that.

Another responsibility of an auditor includes the request for management to supply a written and signed assertion. Why is an assertion so important you may ask? The simple answer is that auditors base their opinion, conclusion, or findings on the information provided by management. Because of this, management is responsible for explicitly stating to the users of their audit report that the information within the report is complete and accurate. This is all outlined as part of the assertion. If management will not provide this assertion, an auditor will be required to provide a modified opinion.

 

Auditor skills

What Skills Do Auditors Need?

Auditors are required to retain the type of skills such as proper education, industry background, and working knowledge when acting as an external auditor under SSAE 18. Having the right type of expertise is particularly essential because auditors are oftentimes required to exercise their own professional judgement in determining whether certain criteria are met or if an opinion should be qualified. In addition to having the right type of proficiency, external auditors are also expected to follow certain ethics requirements. These requirements are outlined in the AICPA’s Application Code of Professionalism.

Depending on the type of audit or attestation engagement underway, the type of designations required will likely differ. A good place to start is at CPA firms. If your organization requires an attestation engagement, the report will only be legitimate if it is signed by a CPA or CPA firm.

This is, however, just the beginning. Attestation services can include a number of different processes from financial services, information technology services, cryptocurrency, oil and gas, health care and the list goes on. When engaging an external auditor to perform these services, doing the proper due diligence such as checking designations such as CISSP, CISA, or past references should be reviewed to determine whether those working on the engagement have the right type of background.

 

Why is auditing important

Why are Auditing and the Auditor Important?

Many times, people cringe at the sight of auditors, but it is important to understand what auditors do and their function in creating a better business. Auditors provide the opportunity for business owners to incorporate independence into the review process of their internal control program. Additionally, the process helps to define gaps, weak controls, and possible risks. Moreover, recognizing the different functions auditors can provide, and using their services as an asset, can ultimately provide companies with an edge over their competitors.

Do Auditors Get Audited?

In fact, yes, auditors do get audited by a third-party auditor. This is done as a way to determine whether a CPA firm and the individuals working there have the correct technical knowledge and that processes are in place to follow planning and reporting requirements. The AICPA Peer Review Program is completed once every three years.
