Segregation of Duties Best Practices to Stop Accounting Errors

Segregation of duties serves as a fundamental building block of sustainable risk management and internal controls for businesses. This control principle divides responsibilities among different individuals to prevent any single person from having complete control over critical business processes.

The concept requires that no employee or group can both initiate and conceal errors or fraud during their normal duties. The Association of International Certified Professional Accountants (AICPA) defines segregation of duties as “shared responsibilities of a key process that disperses the critical functions of that process to more than one person or department”.

Why Segregation of Duties Matters

Organizations face significant financial risks when one person controls multiple aspects of business transactions. Over 14% of fraud is detected by internal audits, but globally, fraud costs businesses $3.7 trillion, making proper controls essential for financial protection.

Organizations with inadequate controls face substantial risks. When a single employee handles cash receipts, records transactions, and performs bank reconciliations, they can manipulate records to conceal theft. Without proper separation, fraudulent activities may continue undetected for months or years, resulting in significant financial losses and damaged stakeholder trust.

Regulatory compliance requirements also drive the need for proper segregation. Sarbanes-Oxley (SOX) requires publicly traded companies to document and certify their financial controls, with both the CEO and CFO signing off on documents stating that controls are in place and compliant.

Key Areas for Application

Financial processes present the highest risk areas requiring segregation of duties. Record keeping roles—individuals who create and maintain financial records for an organization’s transactions must be segregated from issuing or approving those transactions.

Cash handling represents a critical area for control. One individual opens envelopes containing checks, while another individual enters the checks into the accounting system. This separation prevents any single person from both receiving and recording payments, reducing theft opportunities.

Authorization roles require careful attention. Individuals who evaluate and approve transactions should be segregated from recording, reconciling, or reviewing those transactions. This creates natural checks within the approval process.

Asset custody presents another risk area. Individuals who manage or access physical assets like inventory or cash, should not also be responsible for recording inventory, reconciling bank accounts, or approving transactions.

Practical Steps for Small Businesses

Small organizations often struggle with segregation of duties due to limited staff. In smaller organizations or departments with limited staffing, achieving full segregation of duties may be impractical. This creates the need for compensating controls.

Begin by identifying key functions that involve financial transactions, data management, and other activities at risk for serious errors and fraud. Focus on the most critical processes first rather than attempting to address everything simultaneously.

Document current roles and responsibilities clearly. Establish clear boundaries between the key processes and the tasks. Designate primary and secondary roles to ensure operational continuity without compromising the controls.

Create a segregation matrix to visualize potential conflicts. A segregation of duties matrix visually represents the job roles and specific tasks of the people involved in a critical process. This tool helps identify where duties can be separated and where compensating controls are needed.

Addressing Common Challenges

When proper segregation cannot be achieved, compensating controls become essential. Management review of key financial reports and transactions can serve as an essential control to catch anomalies early. Regular oversight provides a layer of protection when duties cannot be fully separated.

Independent reconciliations offer another compensating control. Having a third party perform reconciliations, such as bank statement reviews or inventory counts, ensures an additional layer of scrutiny.

Cross-training staff helps address the challenge of limited personnel. An organization may have a multi-person accounting team, yet only one person knows how to complete journal entries. The organization can train the second person, handing part of the journal process to them, to effectively segregate duties.

Technology can help enforce separation when human resources are limited. Adding restrictions for staff members in the ERP system can help segregate duties. System controls can prevent users from accessing incompatible functions.

Best Practices for Establishment

Regular review of duties and responsibilities ensures controls remain effective as organizations grow and change. Unit management should rotate key internal control responsibilities to enhance segregation of duties and identify potential lapses.

Documentation proves essential for demonstrating compliance. It should be possible to demonstrate segregation of duties to an outside party. Procedures and authorizations are documented to prove that a system of control includes segregation of duties.

Management involvement remains critical throughout the process. Ultimately, managers bear the responsibility for the internal controls. Whenever anyone at the staff level sees a problem, they bring it to management, who is responsible for correcting the issue.

Employee training helps ensure staff understand their roles and the importance of maintaining proper controls. Ideally, everyone in the organization should be well-versed in the company’s segregation of duties policies.

Regular assessment of risk levels guides control establishment. Assess the potential for mistakes or fraudulent transactions. If the segregation of duties is not sufficient to eliminate or adequately reduce the risk of discovering errors, the level of management’s review should be increased over that particular activity.

Segregation of duties provides fundamental protection against fraud and errors while supporting regulatory compliance. Organizations that invest time in properly designing and establishing these controls create stronger financial foundations and protect stakeholder interests.
