What Is Auditors: Duties, Code of Ethics, and Responsibilities

In an increasingly complex business environment, companies face strict regulatory pressure, demands for transparency from stakeholders, and operational and reporting risks that may threaten organizational sustainability.

Even small errors in financial reporting, regulatory non-compliance, or weak internal controls can result in legal sanctions, loss of trust, and long-term reputational damage.

This is where the role of the auditor comes in, not as a “police” merely finding faults, but as an independent control mechanism and strategic partner in building and maintaining that trust.

What Is an Auditor?

In a business context, an auditor is a professional party tasked with providing an independent assessment of the reliability of information, the effectiveness of controls, and an organization’s compliance with applicable policies and regulations.

Auditors occupy a central position within the governance system, functioning as independent “eyes and ears” for the board of directors, senior management, and shareholders.

It is important to distinguish auditors from other roles that are often misunderstood:

• Accountants focus on preparing and recording financial statements.
• Consultants provide recommendations and solutions to improve performance or strategy.

Auditors, on the other hand, independently evaluate whether systems, processes, and information are operating in line with objectives, risks, and sound governance principles.

In other words, auditors do not run the business and do not make operational decisions, but ensure those decisions are supported by reliable controls and information.

Analogy:

If accountants are the “chefs” preparing the meal (financial statements), auditors are the “food testers” who ensure the meal is safe, follows the recipe (standards), and is free from harmful ingredients (material misstatements).

Auditor Code of Ethics

An auditor’s credibility is not only determined by technical competence but primarily by the code of ethics inherent in their profession.

Without ethics, audit results lose their value in the eyes of management and stakeholders. This code of ethics stands on several core principles:

1. Integrity

Auditors must be honest, firm, and demonstrate steadfast principles in all their professional activities.

Integrity means presenting facts transparently, not concealing material deficiencies, and refusing to engage in activities that could tarnish the profession’s name.

2. Independence

This principle has two aspects: independence in fact and in appearance.

Auditors must be free from financial interests, influences, relationships, or pressures that could be considered to impair their objectivity.

Independence ensures that the opinion given is purely based on evidence, without bias or influence from management or any other party.

3. Objectivity

Auditors are obliged to maintain an impartial attitude and be free from bias in exercising professional judgment, gathering evidence, and reporting findings. Every decision must be based on factual analysis and evidence.

4. Confidentiality

Auditors have an obligation to maintain the confidentiality of information obtained during the audit process.

The confidentiality principle obliges them not to disclose such information to unauthorized parties or use that information for personal gain.

Maintaining confidentiality protects the organization’s intellectual and strategic assets.

5. Competence and Due Professional Care (Professionalism)

Auditors must continuously maintain and enhance their professional knowledge and skills.

Each engagement must be performed with adequate expertise, diligence, and professional skepticism in accordance with applicable technical standards.

Competence ensures that audit work adds meaningful value and relevant insights to management.

6. Responsibility

Auditors must consistently comply with applicable laws and regulations and avoid actions that could discredit the profession.

This principle includes respectful conduct, constructive cooperation with auditees, and a commitment to improving overall organizational governance.

Violations of the auditor’s code of ethics not only harm the auditor personally, but can also seriously impact the business, ranging from flawed management decisions to loss of investor and regulatory trust.

Types of Auditors

In practice, auditors exist in several forms, each with distinct roles. Understanding these differences helps management optimize the use of audit functions.

• Internal Auditors
  Internal auditors are part of the organization and focus on evaluating internal controls, risk management, and the effectiveness of business processes. They help management identify weaknesses early and provide insights for continuous improvement.
• External Auditors
  External auditors are independent parties outside the organization who provide assurance on financial statements or specific areas based on their engagement scope. For management and business owners, external auditors serve as objective validation of the company’s information credibility.
• Government / Regulatory Auditors
  These auditors ensure compliance with laws and regulations and the proper use of public resources or statutory obligations. From a business perspective, they represent the interests of regulators and the public.

The key differences among these auditor types lie in their objectives, level of independence, and stakeholders served, yet all contribute to a healthy governance system.

Auditor Functions

The auditor’s role extends far beyond inspection. Strategically, auditor functions include:

• Assurance Function: Auditors provide assurance to management, boards, and owners that the information and systems used as decision-making bases are reliable.
• Risk Control Function: Auditors identify gaps in internal controls and recommend improvements before those gaps are exploited by fraud or lead to operational failures.
• Governance Enhancement Function: Audit findings and recommendations provide valuable input for boards and senior management to strengthen governance structures, policies, and an integrity-driven organizational culture.

Thus, audit reports are not an endpoint, but a strategic decision-support tool to improve business resilience and sustainability.

Duties and Responsibilities

Auditor duties cover various areas depending on the scope and type of audit. In general, auditors are responsible for:

• Assessing the adequacy and effectiveness of internal controls
• Identifying significant risks and potential non-compliance
• Evaluating the reliability of information used by management
• Communicating findings and recommendations objectively

However, it is important to understand the limits of auditor responsibility.

• Auditors are not responsible for business decisions, do not guarantee the complete absence of errors, and do not replace management’s role in running the organization.

The relationship between auditors, management, and business owners is professional and constructive. Auditors are not adversaries, but critical partners who help organizations identify blind spots often overlooked in daily operations.

Required Qualifications for Auditors

Becoming an auditor who adds value to an organization requires a balanced combination of competencies.

• Professional Competence: Understanding business processes, risks, and controls is the main foundation, not merely technical accounting skills.
• Experience and Business Acumen: An effective auditor can understand the industry context, business model, and operational dynamics of the organization being audited.
• Certifications: Various professional certifications reflect standards of competence and ethics, although what matters most is how this knowledge is applied practically.
• Soft Skills: Communication skills, critical thinking, and personal integrity are crucial. Auditors must be able to convey findings clearly, firmly, yet constructively.

Auditor Compensation

The financial compensation of an auditor reflects the responsibility, complexity, and risk of this profession. The salary is not only paid for technical expertise but for the independence, objectivity, and trust they uphold.

General Range Based on Position & Type:

• External Auditor (CPA Firms): Staff ($4,000 – $8,000 USD), Senior ($9,000 – $16,000 USD), Manager ($18,000 – $33,000 USD)*.
• Internal Auditor (Corporation): Staff ($5,000 – $11,000 USD), Senior ($12,000 – $20,000 USD), Head of Audit ($22,000 – $44,000+ USD)*.

Note: Salary figures are illustrative approximations (monthly) converted to USD and vary significantly by country, industry, company size, and experience level.

Conclusion

In the modern business system, auditors hold a strategic role as an integral part of governance.

They are not just compliance checkers, but governance partners who help organizations maintain trust, manage risk, and improve the quality of decision-making.

Auditors safeguard the reliability of information and controls, serving as an objective mirror for management to assess whether the organization remains on the right path.

For business owners and management, fully understanding the role of auditors means utilizing audit as a value-added tool, not a burden, to build a transparent, compliant, and sustainable business.
