Internal Auditing in the contemporary Saudi business environment characterized by rapid growth and continuous regulatory changes has become an indispensable tool to ensure the sustainability and success of companies. It goes beyond merely detecting errors and fraud; it extends to evaluating and enhancing the effectiveness of risk management, control, and governance processes in accordance with best local and international practices. This is often achieved with the support of specialized expertise provided by accounting firms such as Al-Hamli & Partners, which is considered one of the biggest accounting firms in Saudi Arabia and part of the network of approved accounting firms in Saudi Arabia. This article aims to explain the concept of internal auditing, its importance in the Saudi context, and provide a practical guide on how to build an effective internal control system that reduces risks and enhances operational efficiency in the Kingdom.
What Is the Definition of Internal Auditing?
Internal auditing is an independent and objective activity that provides assurance and consulting services aimed at adding value and improving an organization’s operations. It helps organizations achieve their objectives by adopting a systematic and disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes. In Saudi Arabia, internal auditors follow the International Professional Practices Framework issued by the Institute of Internal Auditors (IIA), in addition to complying with local regulations issued by authorities such as the Capital Market Authority (CMA) for listed entities and the Ministry of Commerce.
The Importance of Internal Auditing and the Role of Accounting Firms in Supporting Companies in Saudi Arabia

The role of internal auditing goes beyond compliance to become a strategic partner in achieving the goals of Saudi Vision 2030 especially when collaborating with accounting firms in Riyadh or accounting offices in Jeddah that possess deep local market expertise. Its importance is reflected in several key areas:
- Risk Identification and Assessment:
Helps identify potential risks (financial, operational, strategic, compliance) and assess their impact and likelihood, including risks related to the Saudi regulatory and economic environment.
- Improving Operational Efficiency:
Provides recommendations to enhance operational processes, leading to increased efficiency, reduced waste, and supporting digital transformation in Saudi companies.
- Ensuring Compliance:
Verifies adherence to internal and external regulations, policies, and procedures, such as ZATCA requirements and corporate governance regulations issued by the Ministry of Commerce and CMA.
- Asset Protection:
Contributes to safeguarding company assets from theft, fraud, and misuse, while strengthening control over financial and human resources.
- Supporting Decision-Making:
Provides accurate and objective information that enables management to make informed decisions. Accounting firms play a vital role in analyzing financial data and delivering insights.

Components of an Effective Internal Control System in Saudi Companies
To build a strong internal control system in Saudi companies, it should include the following key components in line with the COSO framework, often in collaboration with a legal accounting office:
- Control Environment
The control environment is the foundation of all other components. It includes management’s integrity and ethical values, commitment to competence, management philosophy and operating style, organizational structure, and the assignment of authority and responsibilities. Senior management must set the tone by adhering to ethical values and fostering an environment that promotes control and compliance with local regulations.
- Risk Assessment
The company must identify and analyze risks related to achieving its objectives. This includes identifying internal and external risks, assessing their likelihood and impact, and determining how to manage them. The risk assessment process should be continuous and dynamic, taking into account changes in the Saudi operational and regulatory environment.
- Control Activities
Policies and procedures designed to ensure management directives are carried out, including:
- Segregation of Duties: Ensuring that all tasks related to a single transaction are not concentrated in the hands of one individual (e.g., separating authorization, recording, and payment responsibilities).
- Authorization and Approvals: Defining authority levels for approving transactions in accordance with established powers and policies.
- Periodic Performance Reviews: Comparing actual performance against planned targets and identifying variances.
- Physical Controls: Safeguarding physical assets (such as inventory and cash) as well as digital assets.
- IT Controls: Protecting data and systems from unauthorized access, in line with cybersecurity regulations in the Kingdom.
- Information and Communication
Relevant information must be identified, collected, processed, and communicated in a form and within a timeframe that enables employees to perform their responsibilities effectively. This includes accounting information systems,reports of internal auditing services and external auditing services, and effective communication channels within the organization, with an emphasis on the importance of communicating with regulatory authorities when necessary.
- Monitoring
The effectiveness of the internal control system must be monitored over time. This can be achieved through ongoing monitoring activities (such as daily managerial reviews) or through separate evaluations (such as periodic internal audits). The objective is to ensure that the internal control system operates as intended and is adjusted as necessary to keep pace with changes.

Steps to Build an Effective Internal Auditing System in Saudi Arabia with the Support of Accounting Firms Like Al-Hamli & Partners
- Obtaining Support from Senior Management and the Board
Support from senior management and the Board of Directors is a cornerstone for the success of the internal audit function. There must be a clear commitment from leadership to the importance and independence of internal auditing, along with providing the necessary resources, in line with corporate governance requirements in the Kingdom.
- Defining the Scope and Charter of Internal Auditing
An internal audit charter must be established to define the purpose, authority, and responsibilities of the internal audit function. The scope of audit activities should also be clearly defined to cover all operations and activities within the company, taking into account local regulations and regulatory requirements.
- Hiring a Qualified and Independent Internal Audit Team
The team should consist of qualified professionals with deep expertise and strong knowledge of the Saudi market, while ensuring full independence. External expertise from accounting firms such as Al-Hamli & Partners can also be leveraged to enhance team efficiency and ensure objectivity.
- Developing a Risk-Based Audit Plan
Instead of random auditing, the internal audit team should develop an annual audit plan based on a comprehensive risk assessment. This ensures that audit efforts are focused on the most critical and high-risk areas, including risks related to compliance with Saudi regulations.
- Executing Audits and Reporting
Internal auditors must perform audit engagements in accordance with international professional standards and gather sufficient and appropriate evidence. Upon completion of the audit, detailed reports are prepared outlining findings, recommendations, and proposed action plans to address deficiencies, and are submitted to management, the Board of Directors, and the Audit Committee.
- Follow-Up and Continuous Evaluation
The role of internal auditing does not end with issuing the report. The implementation of recommendations must be followed up and their effectiveness evaluated. The internal audit plan should also be continuously reviewed and updated to keep pace with changes in the business environment and emerging risks, ensuring the ongoing effectiveness of the internal control system in the evolving Saudi environment.
