Smaller companies often assume that fraud is a problem for large organizations. Todd Muslow, a certified public accountant in Shreveport, Louisiana, sees the opposite pattern. Closely held businesses are frequently more exposed, because the same trust and informality that make a small team efficient also create openings when controls are weak. Building a few structured safeguards reduces that exposure without turning a small office into a bureaucracy.
The most common vulnerability is concentration of duties. In many small businesses, one person handles billing, deposits, vendor payments, and bank reconciliation. That arrangement gives a single individual the ability to both create a transaction and conceal it. Separating these functions is the single most effective control an owner can put in place. When the person who writes checks is not the person who reconciles the account, and the person who records receivables is not the person who handles cash, the opportunity to divert funds quietly shrinks.
For very small teams, complete separation may not be possible. Todd Muslow advises owners to compensate by inserting themselves into the process. An owner who personally reviews the monthly bank statement before it is reconciled, opens the bank mail, or signs checks above a set amount introduces oversight that a sole bookkeeper cannot work around. The control does not require a large staff. It requires the owner’s consistent attention.
Vendor management is another area worth structuring. Fictitious vendors and inflated invoices are recurring schemes. Maintaining an approved vendor list, requiring documentation before a new vendor is paid, and periodically reviewing the vendor master file for duplicates or unfamiliar names helps catch these schemes. Todd Muslow suggests that an owner occasionally review payments to vendors they do not recognize, since an unfamiliar name on a payment register is one of the simpler warning signs to spot.
Payroll deserves similar attention. Ghost employees, unauthorized rate changes, and inflated hours all appear in payroll fraud. An owner who reviews the payroll register, confirms that every name corresponds to a real employee, and approves rate changes personally closes off common avenues.
Documentation supports every control. Approval processes work only when they are recorded. Todd Muslow recommends written procedures for purchasing, expense reimbursement, and payment authorization, even in a small office. The procedures need not be elaborate. They need to be clear about who can approve what and to require support for transactions. When a process is documented, deviations become visible.
Reconciliation on a regular schedule remains one of the strongest detective controls. Discrepancies that surface in a timely monthly reconciliation are far easier to investigate than those discovered a year later. Technology can help, but it does not replace oversight. Accounting systems can restrict user permissions, require approvals, and produce audit trails that record who entered or changed a transaction. Configuring those features and reviewing the audit trail periodically adds protection.
Todd Muslow frames internal controls as protection for the business and for the people in it. Clear procedures protect honest employees from suspicion and remove the temptation that opportunity creates. For owners unsure where to start, Todd Muslow recommends a simple review. Map who handles each step of the cash, billing, and payment cycles, identify where one person controls too much, and add a checkpoint. That single exercise often reveals the gaps that matter most and points directly to the controls worth building first.
