What is the essential principle of an appropriate division of duties in internal controls?

• A. That no person should handle a transaction from beginning to end.
• B. All transactions require dual signatures for approval.
• C. Employees should rotate duties every quarter.
• D. Transactions should be entered into the system within 24 hours.

Answer: (A)

Separating duties among different individuals is about preventing a single person from handling a transaction from start to finish. This creates checks and balances that reduce both errors and opportunities for misappropriation. In practice, responsibilities are divided so that one person initiates or approves a transaction, another records it, another handles custody of assets, and a separate party reviews or reconciles the records. For example, a purchase might be initiated by a requester, approved by a supervisor, the accounting entry prepared by a clerk, and a separate person reconciling the bank or vendor statements. While other controls like requiring dual signatures, rotating duties, or ensuring rapid data entry can support this goal, the core principle remains that no single person should complete a transaction from beginning to end.
