Authorization and approval controls require an appropriate person to review or authorize a transaction before it proceeds. This places a deliberate checkpoint between an accounting action and its completion, helping organizations manage risk and support reliable reporting. The control also creates evidence that reviewers can examine, making it relevant to both internal monitoring and external audit work.
Segregation of duties reduces the concentration of responsibility for related accounting tasks. By distributing activities among different individuals, an organization can make errors or irregularities less likely to pass through the entire process without detection. This principle is especially important where control activities must protect assets while also preserving the accuracy and completeness of accounting records.
Access controls restrict who can perform or approve actions, while automated controls apply programmed procedures consistently. Manual controls depend on people carrying out the required review or action. Organizations may combine these approaches, using technology for execution or restriction and human review within the accounting process.
They provide separate checks on accounting information and control performance. Reconciliations help compare records so discrepancies can be identified, while independent reviews add examination by someone outside the original activity. Together, these activities support detection of errors and irregularities and help produce accounting records that are more accurate, complete, and suitable for audit evidence.
An organization can align specific actions with the risks affecting a process, then assign authorization, segregation, reconciliation, access, or review controls where they are needed. It should determine whether each activity is manual, automated, or combined and retain evidence of operation. This structure connects daily accounting work with reliable reporting, asset protection, and compliance.
Evidence may show that an approval occurred, duties were separated, access was restricted, records were reconciled, or an independent review was performed. Auditors can use this information to assess how the organization’s control system operates and whether accounting processes support reliable records. Documentation also links control performance to compliance with laws and organizational policies.
