internal control refers to the policies, procedures, and processes that a company has in place to ensure the integrity of its financial reporting, the efficiency of its operations, and compliance with laws and regulations. The auditor's assessment of a company's internal controls is an important part of an audit because it helps the auditor to determine the nature, timing, and extent of other audit procedures that need to be performed. The auditor will evaluate the design and effectiveness of the company's internal controls, and will assess the risk of material misstatement in the financial statements. If the auditor determines that the company's internal controls are not sufficient to provide reasonable assurance that the financial statements are free from material misstatement, the auditor will need to perform additional procedures to address the increased risk.

According to W.W.BIGG " internal control is best regarded as indicating the whole system of control, finance and otherwise, established by the management in the conduct of a business, including internal check, internal audit and other forms of control."


Internal control refers to the policies and procedures that a company has in place to ensure the reliability and integrity of its financial reporting, as well as the effectiveness and efficiency of its operations. Internal control systems can help a company to prevent and detect errors and fraud, and to ensure compliance with laws and regulations.
The scope of internal control in an audit refers to the extent to which the auditor will assess the company's internal control system. This typically includes reviewing the design of the controls, testing their effectiveness, and evaluating the overall control environment.

The auditor's assessment of internal control is an important part of the audit process, as it helps the auditor to determine the extent to which the company's financial statements can be relied upon. If the internal control system is weak or inadequate, the auditor may need to perform additional audit procedures to compensate for this.
There are several advantages of internal control:

1. Enhanced audit efficiency: A strong system of internal control can help to reduce the scope of the audit and make the audit process more efficient, as the auditor can rely more on the controls in place rather than having to perform extensive testing.

2. Improved audit quality: A robust system of internal control can help to ensure the accuracy and reliability of a company's financial reporting, which can lead to a higher quality audit.

3. Reduced audit risk: If the internal control system is weak or inadequate, the auditor may need to perform additional audit procedures to compensate for this, which can increase the risk of the audit. By assessing the internal control system, the auditor can identify any weaknesses and take appropriate steps to mitigate this risk.

4. Enhanced investor confidence: The auditor's assessment of the company's internal control system can provide assurance to investors and other stakeholders that the financial statements are reliable and that the company has appropriate controls in place.

5. Compliance with professional standards: Auditing standards require the auditor to assess the company's internal control system as part of the audit process, so a thorough assessment of internal control is essential to ensure compliance with these standards.
There are a few potential disadvantages of internal control :

1. Cost: Implementing and maintaining a robust system of internal control can be costly, as it may require investing in technology and resources, as well as ongoing training and monitoring.

2. Complexity: A complex internal control system may be difficult to understand and navigate, which can make it challenging for auditors to assess its effectiveness.

3. Inflexibility: A rigid system of internal control may be inflexible and unable to adapt to changing circumstances or business needs. This can hinder the company's ability to innovate and respond to new opportunities.

4. Reliance on controls: While internal controls can be an important part of the audit process, they are not a substitute for substantive audit procedures. Auditors must still perform testing and other procedures to obtain sufficient evidence to support their opinions. Relying too heavily on internal controls can lead to an over-reliance on them and a reduction in the overall effectiveness of the audit.
There are several principles that are generally considered to be important in the design and implementation of a good internal control system in the context of an audit:

Relevance: The internal control system should be relevant to the organization's business activities and objectives.

Effectiveness and efficiency: The internal control system should be effective at achieving its intended objectives, and should be designed and implemented in a way that is efficient and cost-effective.

Integrity: The internal control system should be designed to promote ethical behavior and protect the organization's reputation.

Confidentiality: The internal control system should protect sensitive information and prevent unauthorized access or disclosure.

Compliance: The internal control system should be designed to ensure compliance with relevant laws and regulations.

Robustness: The internal control system should be able to withstand challenges and continue to operate effectively under different circumstances.

By following these principles, an organization can design and implement an internal control system that is effective, efficient, and able to support the reliability and integrity of its financial reporting.

What is internal audit

Internal audit is an independent, objective assurance and consulting activity that helps an organization to improve its operations by evaluating and improving the effectiveness of its risk management, control, and governance processes. Internal audit is an internal function that reports to the board of directors or the audit committee, and is separate from the organization's operating units.

The role of internal audit is to provide assurance that an organization's risk management, control, and governance processes are operating effectively. This may involve reviewing the design and implementation of controls, testing their effectiveness, and making recommendations for improvement. Internal audit may also provide consulting services to help the organization identify and address risks and improve its operations.

Internal audit is an important function that can help an organization to identify and address potential problems before they become significant issues. It can also provide assurance to stakeholders that the organization's controls and processes are operating effectively.


The primary objective of internal audit is to provide independent, objective assurance to an organization's board of directors, audit committee, and management that the organization's risk management, control, and governance processes are operating effectively.

1. Internal audit helps to improve an organization's operations by evaluating and improving the effectiveness of its risk management, control, and governance processes. It does this by:

2. Reviewing the design and implementation of controls to ensure that they are appropriate and effective.

3. Testing the effectiveness of controls to ensure that they are operating as intended.

4. Providing recommendations for improvement to help the organization address any weaknesses or deficiencies identified during the audit.

5. Providing assurance to the board of directors and audit committee that the organization's controls and processes are operating effectively.

6. Providing consulting services to help the organization identify and address risks and improve its operations.

Overall, the objective of internal audit is to help the organization achieve its strategic objectives by providing assurance that its risk management, control, and governance processes are operating effectively.
Here are ten key differences between internal audit and external audit:

1. Independence: Internal audit is an internal function that reports to the board of directors or the audit committee, while external audit is carried out by an independent third party.

2. Objective: The primary objective of internal audit is to provide assurance to the organization's board of directors, audit committee, and management that the organization's risk management, control, and governance processes are operating effectively. The primary objective of external audit is to provide assurance to external stakeholders that the organization's financial statements are reliable and prepared in accordance with relevant accounting standards.

3. Scope: Internal audit may cover a wider range of topics and activities within an organization, while external audit is typically focused on the financial statements and related disclosures.

4. Frequency: Internal audit is typically conducted on a more frequent basis than external audit.

5. Reporting: Internal audit reports to the organization's board of directors or audit committee, while external audit reports to external stakeholders.

6. Responsibility: Internal audit is responsible for evaluating the organization's internal control system, while external audit is responsible for expressing an opinion on the organization's financial statements.

7. Standards: Internal audit is generally subject to professional internal audit standards, while external audit is subject to professional auditing standards.

8. Type of assurance: Internal audit provides assurance on the effectiveness of the organization's internal control system, while external audit provides assurance on the reliability of the organization's financial statements.

9. Nature of work: Internal audit may provide consulting services to help the organization identify and address risks and improve its operations, while external audit is typically focused on testing and verifying the accuracy of the financial statements.

10. Legal liability: Internal audit is not subject to the same legal liability as external audit, as it is not required to express an opinion on the organization's financial statements.

Overall, internal audit and external audit are two different types of assurance activities that serve different purposes and have different characteristics.
Internal check is a system of checks and balances that is designed to ensure the accuracy and reliability of an organization's financial and operational information. Internal check systems are an important part of an organization's internal control system, and are typically put in place to prevent errors and fraud, and to ensure compliance with laws and regulations.

Internal check systems can take many forms, and may include segregation of duties, physical controls, and approval and authorization processes. For example, an organization may implement internal check procedures to ensure that there is a separation of duties between the individuals responsible for processing transactions, preparing financial statements, and reconciling accounts.

Internal check systems are an important tool for auditors, as they can provide assurance that the financial and operational information used in the audit is accurate and reliable. Auditors may review and test the effectiveness of an organization's internal check system as part of the audit process.

Internal check systems are designed to prevent errors and fraud, and to ensure compliance with laws and regulations, which can help to ensure the reliability and integrity of the financial statements.

In addition to providing assurance to the auditor, internal check systems can also have the following objectives:

1. Improved efficiency: Internal check systems can help to streamline processes, identify inefficiencies, and prevent errors and waste, which can lead to cost savings and improved profitability.

2. Enhanced decision-making: Internal check systems can provide management with accurate and timely financial information, which can facilitate better decision-making and strategic planning.

3. Reduced risk of fraud: Internal check systems can help to prevent and detect fraudulent activities, such as embezzlement or financial statement manipulation, which can have serious consequences for a company.

4. Compliance with laws and regulations: Internal check systems can help a company to ensure compliance with relevant laws and regulations, which can help to avoid costly fines and legal penalties.
There are several advantages of internal check:

1. Enhanced audit efficiency: A strong system of internal check can help to reduce the scope of the audit and make the audit process more efficient, as the auditor can rely more on the controls in place rather than having to perform extensive testing.

7. Clear documentation: The internal check system should be well-documented, with clear policies and procedures that are understood and followed by all relevant parties.

By following these essentials, an organization can design and implement an internal check system that is effective, efficient, and able to support the reliability and integrity of its financial reporting.

Internal audit and internal check are two different but related concepts. Internal audit is an independent, objective assurance and consulting activity that helps an organization to improve its operations by evaluating and improving the effectiveness of its risk management, control, and governance processes. Internal check, on the other hand, refers to the system of checks and balances that is designed to ensure the accuracy and reliability of an organization's financial and operational information.
Here are some key differences between internal audit and internal check:

1. Scope: Internal audit may cover a wide range of topics and activities within an organization, while internal check is focused on the accuracy and reliability of financial and operational information.

2. Purpose: The primary purpose of internal audit is to provide assurance that an organization's risk management, control, and governance processes are operating effectively. The primary purpose of internal check is to prevent errors and fraud, and to ensure compliance with laws and regulations.

3. Reporting: Internal audit reports to the organization's board of directors or audit committee, while internal check is a part of the organization's internal control system.

4. Responsibility: Internal audit is responsible for evaluating the organization's internal control system, while internal check is a part of the control system itself.

Overall, internal audit and internal check are two different but related concepts that play important roles in helping organizations to improve their operations and achieve their strategic objectives.

In-depth auditing refers to a thorough and comprehensive review of an organization's financial records and operations. This type of audit typically involves a more detailed and extensive examination of the company's financial statements and supporting documentation than a typical financial statement audit. In-depth audits are often used to identify and address specific issues or concerns that may not be apparent from a standard audit. They may be conducted for a variety of reasons, such as to assess the effectiveness of internal controls, to investigate potential fraud or mismanagement, or to evaluate the overall financial health of the organization. In-depth audits typically involve a higher level of analysis and may require the auditor to delve more deeply into the company's financial and operational data in order to understand its underlying financial position and performance.

Taylor and Perry have defined Auditing in depth as "the examination of the system applied within a business entailing the tracking of certain transactions from there origin to their conclusion, investigating at each stage the records created and their authorisation."
