Which five essential internal controls must small businesses have?

✓ Accepted answer

Small businesses must implement five core internal controls: segregation of duties, mandatory invoice verification, dual approval for payments, regular bank reconciliation, and restricted access to financial systems.

• Segregation of Duties: Ensure the person requesting payment is different from the person approving it. This prevents a single employee from both creating a fake invoice and authorizing the payout, a primary cause of fraud in lean teams.
• Vendor Verification: Require a second point of contact for new or changed vendor banking details. Fraudsters often alter email signatures; verifying via a known phone number or in-person contact stops fake invoice scams effectively.
• Dual Approval Thresholds: Set a limit, such as $1,000, where any payment exceeding this amount requires sign-off from two different managers or owners. This creates a check-and-balance system without needing a full audit team.
• Monthly Reconciliation: Compare bank statements against internal cash books every month. This immediate review process highlights unauthorized transactions or discrepancies long before they compound into significant losses.
• Role-Based Access: Limit financial software permissions so only specific roles can delete records or add vendors. Regularly review access logs to ensure former employees do not retain login credentials.

If you discover unexplained gaps in your cash flow or receive repeated requests from unknown vendors for urgent payment via wire transfer, contact your bank’s fraud department and a forensic accountant immediately.
