Internal control review showing an Australian business reviewing financial processes, risk controls, approvals and business operations

How Internal Control Reviews Can Help Identify Business Risks

September 19, 2026•16 min read

A business can have good people, reliable software and strong financial results — and still have weaknesses in the way work is controlled.

A payment may be approved by the wrong person. A customer refund may not be independently checked. Payroll changes may be made without proper review. Important financial information may rely on one employee who knows how everything works but has no documented backup process.

These issues can remain invisible until something goes wrong.

An internal control review can help Australian businesses identify weaknesses in their processes before they develop into larger financial, operational, compliance or governance problems.

Rather than simply asking whether a business has policies in place, an internal control review looks at how controls actually operate. It can examine who is responsible, how transactions are authorised, how information is checked, where risks exist and whether the controls in place are appropriate for the business.

For growing businesses, this can be particularly useful because processes that worked when a business was smaller may become less effective as transaction volumes, employees, customers and financial complexity increase.

Quick answer: What is an internal control review?

An internal control review is a structured assessment of the policies, procedures and controls a business uses to manage risk and protect its financial and operational processes.

The review may consider areas such as:

  • Financial approvals

  • Bank and account reconciliations

  • Accounts payable and receivable

  • Payroll processes

  • Access to accounting systems

  • Revenue and customer transactions

  • Inventory and assets

  • Financial reporting

  • Segregation of duties

  • Management approvals

  • Documentation and record keeping

  • Compliance processes

  • IT and system access

  • Fraud and error prevention

The purpose is not necessarily to find that something has gone wrong. Instead, it is to identify where a process could fail, where responsibilities are unclear or where existing controls may not be working as intended.

ASIC notes that internal audit can contribute to governance by reviewing and making suggestions about an organisation's financial and non-financial control environment, risk identification and monitoring processes, and governance processes.


Why internal controls matter to business risk

Business risk is broader than financial loss.

Australian businesses can face risks relating to economic conditions, regulation, technology, cyber security, legal issues, staffing, customers, suppliers and other operational factors. Business.gov.au recommends identifying, analysing, evaluating and treating risks rather than waiting for problems to occur.

Internal controls form part of how a business manages many of these risks.

For example, consider a business where one employee can:

  1. Create a new supplier,

  2. Approve the supplier invoice,

  3. Enter the payment into the accounting system, and

  4. Release the payment.

The business may trust the employee completely. However, the process itself creates a concentration of responsibility.

A control review could identify the lack of separation between these activities and recommend a more appropriate approval process.

The same principle applies to many areas of a business.

The question is not simply:

“Do we trust our employees?”

It is:

“Have we designed our processes so that errors, inappropriate transactions and other risks can be identified before they cause significant damage?”

That distinction is important.


What can an internal control review identify?

An internal control review can uncover different types of weaknesses depending on the business and the scope of the review.

1. Lack of segregation of duties

Segregation of duties means separating important responsibilities so that one person does not have excessive control over a transaction or process.

For example, different people may be responsible for:

  • Creating suppliers

  • Approving purchases

  • Processing payments

  • Reconciling bank accounts

  • Reviewing financial reports

Small businesses may not always have enough employees to completely separate every responsibility.

That does not mean controls are impossible. Alternative controls may be appropriate, such as additional management review or regular independent reconciliations.

A review can help identify where duties are concentrated and whether compensating controls are needed.

2. Weak approval processes

A business may technically have an approval process but not enforce it consistently.

For example, the documented policy might require management approval for purchases above a particular amount, while employees regularly make purchases without documented approval.

An internal control review can compare the intended process with what actually happens.

That distinction can reveal a significant gap between control design and control operation.

3. Inadequate reconciliations

Reconciliations are an important way to identify discrepancies.

Businesses may reconcile:

  • Bank accounts

  • Credit cards

  • Payroll accounts

  • Accounts receivable

  • Accounts payable

  • Inventory

  • Clearing accounts

  • Balance-sheet accounts

If reconciliations are incomplete, delayed or not independently reviewed, errors can remain in the accounting records.

ASIC states that companies have obligations to maintain financial records that correctly record and explain transactions and financial position and performance, and that appropriate controls and processes form part of maintaining complete and accurate records.

An internal control review can therefore look beyond whether a reconciliation exists and consider whether it is performed consistently, reviewed appropriately and followed up when differences arise.

4. Excessive system access

Accounting and business systems often contain sensitive financial information.

A control review may examine:

  • Who has administrator access

  • Who can create or modify suppliers

  • Who can change customer records

  • Who can approve payments

  • Who can process payroll

  • Who can modify accounting data

  • Whether former employees still have access

  • Whether access levels match employees' responsibilities

Access should generally reflect what a person needs to perform their role.

As businesses grow, system permissions can become outdated unless someone regularly reviews them.

5. Poor documentation

A process that exists only in someone's memory can become a business risk.

This is particularly common when one employee has been responsible for a process for several years.

If that person leaves, takes extended leave or changes roles, the business may discover that nobody else knows exactly how the process works.

An internal control review can identify processes that need:

  • Documented procedures

  • Defined responsibilities

  • Approval requirements

  • Backup arrangements

  • Review points

  • Escalation procedures

Business.gov.au notes that clear policies, procedures and processes can help clarify responsibility, support consistent decisions, meet legal and regulatory requirements and keep a business operating during disruption.


Internal control reviews can reveal risks that financial reports do not show

Financial statements can tell you what happened financially.

They do not necessarily explain why something happened or whether the process behind the numbers is reliable.

For example, a business might report strong revenue growth while having:

  • Weak customer credit controls

  • Increasing overdue accounts

  • Unapproved discounts

  • Inconsistent revenue recognition processes

  • Poor debtor follow-up

  • Inadequate cash controls

The financial statements may initially look healthy.

A control review can investigate the processes behind those numbers and identify weaknesses that management reporting alone may not reveal.

This is one reason internal controls should be considered alongside financial reporting rather than as a completely separate issue.


7 business risks an internal control review can help identify

The specific risks will depend on the organisation, but an internal control review may highlight issues such as:

1. Financial reporting risk

Errors in accounting records can affect management reports, financial statements, tax information and business decisions.

Controls can help reduce the likelihood that material errors remain unidentified.

2. Fraud risk

Controls cannot eliminate fraud risk, but appropriately designed processes can make inappropriate activity more difficult and increase the likelihood that unusual transactions are detected.

3. Cash-flow risk

Weak controls over invoicing, collections, payments or cash management can contribute to avoidable cash-flow pressure.

4. Compliance risk

A business may have obligations relating to taxation, payroll, financial reporting, industry regulation or other requirements.

Weak processes can make compliance harder to manage consistently.

5. Operational risk

A business can become dependent on undocumented processes, individual employees or manual workarounds.

These weaknesses can create disruption when circumstances change.

6. Technology and access risk

Inappropriate system access, weak user controls or outdated permissions can increase exposure to unauthorised changes or information access.

7. Governance risk

Management may not receive sufficiently reliable information to understand what is happening within the business.

That can make it harder to identify emerging problems and make timely decisions.

ASIC describes risk identification and management as core responsibilities of directors, including the identification and management of emerging risks.


What does an internal control review actually involve?

The process will depend on the size, structure and objectives of the business.

A practical review may follow several stages.

Step 1: Understand the business

Before testing controls, it is important to understand how the business operates.

This can include reviewing:

  • Business structure

  • Key revenue streams

  • Major expenses

  • Financial systems

  • Staffing structure

  • Approval responsibilities

  • Critical suppliers

  • Customer processes

  • Reporting requirements

  • Existing policies and procedures

A control that is appropriate for a small professional services firm may not be appropriate for a larger organisation with multiple locations and a larger finance team.

Step 2: Identify key processes

The review can focus on processes where weaknesses could have a meaningful impact.

For example:

Purchasing → supplier setup → invoice approval → payment → reconciliation

Or:

Sale → invoice → receipt of payment → bank reconciliation → reporting

Mapping these processes helps show where controls exist and where gaps may occur.

Step 3: Identify risks

The next question is:

What could go wrong?

For each process, consider potential risks such as:

  • Incorrect transactions

  • Unauthorised transactions

  • Duplicate payments

  • Missed revenue

  • Incorrect payroll

  • Data changes

  • Fraud

  • Delayed reconciliations

  • Incomplete records

  • Compliance failures

Business.gov.au recommends analysing risks based on factors including likelihood and potential consequences before deciding how they should be treated.

Step 4: Review existing controls

Once the risks are identified, examine what controls are currently in place.

These could include:

  • Management approvals

  • System permissions

  • Reconciliations

  • Review procedures

  • Dual authorisation

  • Exception reports

  • Supporting documentation

  • Physical controls

  • Independent checks

The review should consider whether the control is appropriately designed and whether it is actually being performed.

Step 5: Test the process

A policy document alone does not prove that a control works.

Depending on the scope, testing might involve reviewing transactions, approvals, reconciliations, access permissions, supporting documentation or evidence of management review.

This can reveal whether the process works consistently in practice.

Step 6: Report findings

The final output should make the findings understandable and actionable.

A useful internal control review should help management understand:

  • What the issue is

  • Why it matters

  • What risk it creates

  • How significant the issue may be

  • What improvement could be made

  • Who should take responsibility

  • Whether follow-up is required

The goal should be practical improvement rather than a report that simply identifies problems.


What are signs your business may need an internal control review?

You do not necessarily need to wait for a major incident.

An internal control review may be worth considering when:

Your business has grown quickly

Processes that worked with five employees may not work effectively with 30.

Growth can introduce new approval levels, systems, locations and responsibilities.

You have changed accounting or business systems

A new accounting platform, payroll system, CRM or payment system can change how information moves through the business.

Controls should be considered as part of that transition.

One person controls too much of the finance process

This can be common in smaller businesses.

If one person handles bookkeeping, payments, reconciliations and reporting, management may benefit from an independent review of the control environment.

You have experienced unexplained errors

Repeated discrepancies, unusual adjustments, duplicate payments or unexplained account movements may indicate a process weakness.

Your financial reporting is regularly delayed

If management cannot obtain reliable financial information on time, the problem may not simply be the reporting process.

There may be weaknesses in the underlying records, reconciliations or review procedures.

You are preparing for an audit

A control review can help identify areas that may require attention before an external audit or assurance engagement.

It does not replace an audit, but it can help management prepare.

Responsibilities are unclear

If employees are unsure who can approve, review or authorise particular transactions, the business may have an avoidable control gap.

Your business has become more complex

Expansion, new entities, new investors, additional funding, acquisitions or multiple operating locations can all change the risk profile of a business.


Internal control review vs external audit

An internal control review and an external audit are not the same thing.

An external audit has a specific purpose, scope and reporting framework. Depending on the entity and circumstances, an audit may involve obtaining evidence to support an opinion on financial statements.

An internal control review is generally more focused on understanding and improving the business's processes and control environment.

A business may conduct a control review:

  • Before an audit

  • Between audit cycles

  • During a period of growth

  • After implementing new systems

  • Following a significant organisational change

  • As part of broader risk management

  • When management wants greater visibility over financial processes

The two can complement one another, but an internal control review should not be described as a substitute for an audit where an audit is required.


How internal control reviews support better business decisions

Internal controls are often discussed in terms of preventing errors and reducing risk.

There is another important benefit: better information.

Business owners and leadership teams make decisions based on information.

If the information is incomplete, delayed or unreliable, the quality of those decisions can be affected.

For example, management may decide to:

  • Hire additional employees

  • Expand into another location

  • Purchase equipment

  • Increase marketing expenditure

  • Seek external funding

  • Change pricing

  • Acquire another business

Those decisions rely on financial and operational information.

Stronger controls can provide greater confidence that the underlying information has been processed, reviewed and reconciled appropriately.

That does not guarantee that a decision will be successful. It simply gives management a stronger information base from which to make the decision.


What happens after an internal control review?

Finding a control weakness is only the beginning.

The business should decide what happens next.

For each significant finding, consider:

  1. What is the underlying risk?

  2. How significant could the impact be?

  3. How frequently could the issue occur?

  4. Is the current control adequate?

  5. What improvement is practical?

  6. Who owns the action?

  7. When should it be completed?

  8. How will management know the improvement is working?

Some weaknesses may require immediate attention.

Others may be lower priority and can be addressed as part of a broader process improvement plan.

The important point is to connect findings with actions.


How often should you conduct an internal control review?

There is no single review frequency that suits every business.

The appropriate approach depends on factors such as:

  • Business size

  • Industry

  • Transaction volume

  • Organisational complexity

  • Regulatory environment

  • Number of employees

  • Financial risk

  • System changes

  • Growth

  • Previous control findings

A business may also benefit from targeted reviews after significant changes rather than relying only on a fixed timetable.

For example, controls could be reviewed after:

  • Implementing new accounting software

  • Changing payroll systems

  • Expanding into a new location

  • Acquiring another business

  • Changing senior finance staff

  • Introducing new payment processes

  • Experiencing a significant error

  • Preparing for an audit or assurance engagement

Risk management should not be treated as a one-off exercise. Business.gov.au recommends regularly reviewing risk management approaches and updating them as circumstances change.


Internal controls should grow with your business

One of the biggest mistakes businesses can make is assuming that controls are something you establish once and then leave unchanged.

A business changes.

Employees change. Systems change. Customers change. Transaction volumes change. Regulations change. The financial risks facing the organisation can also change.

A control that was appropriate two years ago may no longer be sufficient today.

This is particularly important for businesses experiencing growth.

As the organisation becomes more complex, management may need clearer approval structures, stronger reporting, better documentation and greater separation of responsibilities.

An internal control review can provide a structured way to identify where those improvements are needed.

Frequently Asked Questions

What is an internal control review?

An internal control review is an assessment of the policies, procedures and controls a business uses to manage financial, operational, compliance and governance risks. It can identify weaknesses, gaps and opportunities to improve processes.

Can an internal control review detect fraud?

An internal control review can identify control weaknesses that may increase exposure to fraud or make unusual activity harder to detect. However, a control review is not automatically a fraud investigation and should not be presented as a guarantee that fraud will be detected.

Is an internal control review the same as an audit?

No. An internal control review and an external audit have different purposes and scopes. A control review generally focuses on understanding and improving processes and controls, while an audit has a defined assurance purpose and reporting requirements.

Should small businesses review their internal controls?

Small businesses can also benefit from reviewing controls, particularly when one person performs several financial functions. The appropriate level of control should reflect the size, complexity and risks of the business.

When should a business conduct an internal control review?

A review may be useful when a business is growing, changing systems, restructuring responsibilities, preparing for an audit, experiencing recurring errors or becoming more financially complex.

What areas can an internal control review cover?

Depending on the scope, a review can cover financial approvals, purchasing, payments, payroll, reconciliations, revenue, system access, reporting, documentation, segregation of duties and other business processes.

What happens if an internal control weakness is identified?

Management can assess the significance of the weakness, determine the underlying risk, assign responsibility and implement an appropriate improvement. Follow-up can then confirm whether the revised control is operating effectively.


Final takeaway

An internal control problem does not have to become a financial loss, compliance issue or operational disruption before management takes action.

An internal control review gives businesses an opportunity to look at how important processes actually work, identify weaknesses and strengthen controls before problems become more difficult to manage.

For Australian businesses, effective risk management is not simply about reacting when something goes wrong. It involves identifying risks, understanding their potential impact and putting practical measures in place to manage them.

As your business grows, your controls should grow with it.
