How Do I Reduce Fraud Risk in a Small Business?

The typical small business fraud is not a stranger's cyberattack; it is a long-serving, trusted employee with sole control of a financial process — payments, deposits, payroll, or the bank reconciliation — exploiting the absence of a second pair of eyes, often for years.

Small firms are structurally exposed because one person often does everything. The remedy is not suspicion of people; it is the design of process — making sure no single person can both commit and conceal.

Segregation of duties is the master control: the person who enters bills should not approve payments; the person who approves payments should not reconcile the bank; the person who runs payroll should not be able to add employees unreviewed. In a five-person office, perfect separation is impossible — but owner participation substitutes: the owner reviews bank activity weekly (directly in the bank portal, not through reports prepared by the person being checked), approves every new vendor and every payee change, and signs off on payroll summaries.

Around that core, a short list of controls covers most schemes: dual authorization on electronic payments above a set threshold; call-back verification on any emailed change to banking details — the signature move of payment-diversion fraud; mandatory vacations with duties actually reassigned; surprise counts where cash or inventory matters; and a culture where the owner's visible engagement with the numbers is itself a deterrent. Report incidents to police and the Canadian Anti-Fraud Centre — silence protects the next fraudster.
