From Accountant to Internal Auditor - Opportunity of Growth

Internal Check Vs Internal Audit: Understanding The Key Differences

Internal audit and compliance audit are both essential functions in any organisation. In recent years, both services have risen in importance, signifying critical control components of an organisation’s structure. However, whilst compliance is increasingly commoditised (and subject to pricing pressure), there is significant opportunity to generate value for business clients through internal audits.

In mid-tier and top-tier accounting firms, there’s a clear separation between compliance and consulting roles in relation to audits. In these firms, internal audit and compliance professionals will generally collaborate for the benefit of their clients whilst ensuring they have sufficient independence safeguards in place. Smaller firms face greater challenges in separating these roles.

A clear benefit of appointing an external compliance auditor for a smaller firm is the opportunity created for a partner to take on a broader consulting role focusing on governance, technology and processes. Or alternatively, if you provide compliance audit services, then consider the value of an independent consultant auditor for internal audit activities.

What is internal auditing?

Internal auditing is an independent, objective assurance and consulting engagement designed to reduce risk and, importantly, add value by improving an organisation’s governance, strategy and operations.

It helps an organisation accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control and governance processes.

The scope of internal auditing within an organisation is broad and may involve topics such as an organisation’s governance, risk management and management controls over the efficiency of operations, the reliability of financial and management reporting and compliance with laws and regulations.

Internal auditors are not responsible for the execution of company activities. They advise management and those charged with governance regarding how to better execute their responsibilities. External accountants can certainly play a role as a participant at a board or committee level.

Understanding the difference between internal checks and audits is also critical, as internal checks operate within daily processes while internal audits provide an independent review of those controls. 

What’s the value of an internal audit?

A recent report by KPMG (Seeking value through internal audits) identified three specific insights that the leaders and managers of organisations receive from internal audits:

  1. Help assess risks and risk management practices
  2. Develop an informed perspective on emerging risks
  3. Focus on sustainable profit generation

Internal auditors have a specific role in helping firms respond appropriately to risks identified through compliance audits. Often, leaders and managers of firms don’t have the experience and skills to be able to address these risks in a considered manner. An external perspective is required.

What skills are required to conduct an effective internal audit?

The KPMG report outlined above identified the top 5 skills needed for internal audit professionals. These were strong communication, technology skills, critical thinking, understanding markets and having a command of data analytics. Financial and accounting skills are conspicuous in their absence.

Accountants in public practice are in a strong position to provide internal audit support, especially around data analytics. In a recent article, ‘Technology and the Future of Audits’, Steven Watson, our Managing Director, suggested that data analytical tools are enabling auditors to better identify financial reporting, fraud and operational business risks. In particular, the use of Computer Assisted Auditing Techniques (CAATs) in an internal audit can assist with testing various financial oversight functions, including, for example, payroll, accounts payable and accounts receivable, credit cards and fuel card expenditure.

What internal audit services should you consider?

A recent PwC report ‘Maximising the value of internal audits’ provided some great examples of how internal auditors could add value to their business clients, including:

  1. Fireside chats on intangibles, including quality of people, morale, engagement, values, teamwork, communications, culture;
  2. What would you like us to look at? Ask management to define two ideas that may reduce cost, improve control, etc., and include them in the audit plan for internal audit and management to work on;
  3. Provide tools to assist value discovery, for example revenue leakage or duplicate payments;
  4. Integrated risk and assurance mapping to provide a holistic view of risks and the related assurance;
  5. Training sessions in risk management and controls effectiveness for management and the audit committee;
  6. Future focus: things might be working now, but if the business strategy contemplates major change, provide feedback on the organisation’s capacity to implement the new strategy;
  7. Providing feedback on the quality of the risk management framework and processes and challenging their effectiveness.

Develop technical expertise in audit practice

Building a successful career in auditing goes beyond experience and progression. It also requires a strong understanding of internal controls, audit frameworks and how different assurance functions operate within an organisation.

As auditors develop their skills, they are expected to interpret not only financial data but also the systems and controls that support it. This includes understanding how internal processes are structured and how they are evaluated through audit activities.

Internal check vs internal audit

As part of developing technical expertise, it is important to understand the internal check vs internal audit distinction and how both functions contribute to a strong control environment.

Internal checks are embedded within daily operations and designed to prevent errors and irregularities through segregation of duties, approval processes and routine verification procedures. These controls operate continuously as part of normal business activities and form the first line of defence against risk.

Internal audits, on the other hand, provide an independent and structured evaluation of these controls. They assess the effectiveness of risk management, governance and operational processes, offering recommendations for improvement where needed. This independent review helps organisations identify gaps, strengthen controls and support more informed decision-making.

Translating internal check and audit concepts into practice

Knowing the difference between an internal check and an audit helps auditors apply the right approach in different situations.

When to use internal audit and compliance audit

The use of an internal audit and compliance audit depends on the objective of the engagement and the specific needs of the organisation. Internal audits are suited for evaluating processes, identifying risks and strengthening internal controls, while compliance audits focus on ensuring that regulatory, legal and reporting requirements are met.

In practice, organisations benefit from using both approaches at different stages. Internal audits help improve how the business operates, while compliance audits provide assurance that standards and obligations are being followed. Together, they support a more balanced approach to risk management, governance and overall organisational performance.

How can you collaborate with external auditors?

If you’re already providing business clients with financial reports and advice, then you might want to consider taking on the role of ‘internal auditor’ with your business clients. Perhaps this starts with a consulting role to the board, for example, as a data analyst, integrating data and systems to provide a high-level review of internal systems and processes.

If you’re already providing compliance audit services, you may consider partnering with an external specialist who can take on the internal audit or consulting role. Our specialised staff can assist your business in establishing an internal audit function or with the performance of internal audits to complete your existing audit plans.

Strengthen your audit approach with the right balance

Both internal audit and compliance audit play an important role in supporting strong governance, risk management and business performance.

While external audits provide independent assurance and compliance oversight, internal audits offer deeper insight into processes, controls and opportunities for improvement. Taking a balanced approach allows organisations to not only meet regulatory requirements but also strengthen decision-making and long-term outcomes.
