The Differences Between Internal Audit and External Audit

Internal audit and external audit show important differences in terms of their objectives, scopes, and degrees of independence:

Feature Internal Audit External Audit
Objective Improves the organization's operations, adds value, and improves risk, control, and governance processes. Provides an independent opinion on whether the financial statements are accurate and reflect reality.
Independence It is independent within the organization but reports to the organization's management. It is completely independent of the organization and is accountable to shareholders or the public.
Scope Includes financial, operational, compliance, IT, and strategic risks  Usually the accuracy of financial statements and the related internal controls
Reporting To the board of directors, the audit committee, and senior management To shareholders, investors, and regulatory bodies
Timing Continues throughout the year, continuously or periodically. Usually done on an annual basis, at the end of a certain period.

The Internal Audit Process: A Step-by-Step Look

The internal audit process is carried out with a systematic approach and consists of certain stages. 

The internal audit process is addressed in detail in sources such as the guide of the Dokuz Eylül University Internal Audit Unit Directorate. In summary, an internal audit process includes the following steps:

1. Planning Stage

This stage forms the foundation of the internal audit activity. Annual audit plans are prepared, and detailed planning is done for each audit task. It will be appropriate to use the following methods for planning:

  • Risk areas are identified by considering the organization's strategic goals, operational processes, and external environmental factors. 
  • According to the results of the risk assessment, the units, processes, or systems to be audited are selected.
  • For each audit task, the objectives, scope, methodology, resources (audit team, duration), and reporting format are determined.

2. Fieldwork (Implementation) Stage

After the planning step, the audit team goes into the field and carries out data collection and analysis activities. Relevant documents (policies, procedures, financial records), system records, and other data are collected. Interviews and observations are conducted.

Then the design and operating effectiveness of the existing internal control systems are tested. The collected data is analyzed in line with the determined audit criteria and objectives. Anomalies, weaknesses, or areas for improvement are detected.

Finally, the important findings detected during the audit (deficiencies, nonconformities, inefficiencies) and their potential effects are documented.

3. Reporting Stage

After the fieldwork is completed, the audit findings and recommendations are turned into a formal report.

The draft report is shared with the managers of the audited unit and the relevant senior executives. Feedback is received and necessary corrections are made. The final report, prepared in light of the feedback, is presented to the audit committee, senior management, and other relevant stakeholders.

4. Follow-Up Stage

One of the most critical stages of the audit process is the follow-up stage. At this stage,

  • Whether the corrective actions for the reported findings are implemented in a timely and effective manner is tracked.
  • The actions implemented are evaluated in terms of resolving the detected problems.
  • The follow-up results are recorded to provide input for future audit planning, thus supporting the continuous improvement cycle.

Internal audit is an indispensable function for the sustainable success of organizations. Paying attention to elements such as independence, commitment to ethical values, a risk-focused approach, and the use of technology will increase the effectiveness of internal audit.

Learn About Part-Time Leadership and Consulting

A management career does not always require a full-time position. The flexible working models and need for expertise that have become quite widespread today have made alternative career paths such as "part-time executive," "part-time leader," "executive consultant," and "executive coach" possible. 

This model offers a great advantage especially in areas that require expertise, such as internal audit. Because planning an organization's internal audit processes, identifying risk areas, and evaluating control mechanisms require years of experience and industry knowledge. However, not every company has the means to keep a full-time internal audit manager on staff. Platin Yaka is by your side with the part-time leadership model!

Platin Yaka is a platform that brings together experienced leaders who have held senior roles at the largest companies globally and in Türkiye. If you want to strengthen your internal audit planning, nonconformity analysis, risk management, and corporate governance processes, you can get one-on-one support from leaders specialized in internal audit at Platin Yaka. 

What Should Be Considered in Internal Audit? 

To establish and maintain a successful internal audit function, we recommend that you pay attention to the following elements:

  • One of the most fundamental principles of internal audit is independence and objectivity. Internal auditors must be operationally independent of the activities and units they audit.
  • Ethics serves as a moral compass that guides public managers in their decision-making processes. This principle also applies to internal auditors and is critical for them to maintain their independence and objectivity.
  • It is important to focus on critical risk areas in internal audit. The biggest risks that could prevent the organization from reaching its goals should be identified, and audit plans should be prioritized according to these risks.
  • The automation of repetitive audit tasks enables auditors to focus on more strategic and value-adding activities. Data analytics tools can be used to detect risks.
  • In internal audit, the effectiveness of cybersecurity controls should also be evaluated regularly.
  • Internal auditors also need to keep their knowledge and skills up to date. Because internal auditors who are competent in their field can offer effective solutions to the complex problems the organization faces.

Frequently Asked Questions 

Who performs internal audit?

Internal audit is performed by specially trained and certified internal auditors who serve as an independent unit within the organization. These auditors are independent of the organization's operational activities and report directly to senior management or the audit committee.

To whom are internal audit reports presented?

Internal audit reports are usually presented to the Audit Committee, the Board of Directors, and the relevant senior management levels. These reports include audit findings, risks, causes, and recommended corrective actions.

Is internal audit mandatory?

For public institutions, internal audit is generally legally mandatory. In the private sector, having an internal audit unit is a common and recommended practice as part of good corporate governance, especially for large-scale companies and publicly traded companies. These companies can also get support from the leaders on the Platin Yaka platform and from auditors who are experts on the subject. 

Does internal audit cover only financial matters?

No, internal audit does not cover only financial matters. Its scope is much broader and includes many areas such as operational processes, information technology (IT) systems, compliance, strategic risks, and environmental, social, and governance (ESG) matters.

What is fractional leadership? 

Fractional leadership is a flexible model that enables a company to benefit from the strategic direction of an experienced leader for a certain period or on a project basis without employing a full-time executive. This approach offers a strong alternative, especially for companies that find it difficult to bear the financial burden of a full-time senior executive.

Startups, SMEs, and large firms in the process of transformation are among the structures that benefit most from this model. When we think specifically about internal audit, the picture becomes even clearer: a growth-stage company wants to take its risk management and internal control processes to a professional level, but working full-time with an experienced internal audit leader may not be sustainable budget-wise. At this point, fractional leadership is an extremely suitable solution. Thanks to the Platin Yaka platform, you can find the opportunity to work with leaders who have decades of experience in areas such as internal audit, risk management, and corporate governance. Find a Platin Yaka suitable for your company's internal audit needs right away.

Is internal audit a cost or an investment?
