Implementing a strong internal control system is one of the most effective ways to protectÌýbusinessÌýassets andÌýmaintainÌýaccurateÌýfinancial records. Yet manyÌýorganizationsÌýdon’tÌýevaluate their controls until a problem occurs. AÌýmidyearÌýreview can helpÌýyouÌýidentifyÌýweaknesses before they lead to costly errors or fraud. It also givesÌýyouÌýan opportunity toÌýmodifyÌýpolicies and procedures asÌýyourÌýoperationsÌýgrow,Ìýstaffing changesÌýandÌýnew technologiesÌýare implemented.Ìý
Why internal controls matterÌý
RobustÌýinternal controlsÌýwon’tÌýeliminateÌýevery risk. But businesses that regularly evaluate and strengthen their policies and procedures are typically far better positioned to prevent problems, detect issues early andÌýmaintainÌýreliable financial information.Ìý
Weak or outdated controls can expose businesses to a wide range of risks, including employee theft, unauthorized transactions, accountingÌýerrorsÌýand inaccurate financial reporting.ÌýIneffectiveÌýoversightÌýproceduresÌýcan cause fraud schemesÌýtoÌýgoÌýundetected forÌýlong periods.ÌýIn fact, the median fraud scheme lasted 12 months before detection and caused a median loss of $104,000, according toÌýOccupational Fraud 2026: A Report to the Nations,Ìýa recent biennial study published byÌýthe Association of Certified Fraud Examiners (ACFE).Ìý
Strong internal controls are especially important for smaller privateÌýbusinesses, where limited staffing can make it more difficult to separate responsibilities and maintain oversight.ÌýTheÌýrecentÌýACFE report found that organizations with fewer than 100 employees experienced the highest median fraud losses among all business sizes — $126,000 perÌýincident.Ìý
Start withÌýcompanywide accountabilityÌý
Internal controls are most effective when they become part ofÌýyourÌýbusiness’sÌýculture.ÌýYour employees should understand that management takes fraud prevention seriously and that controls exist to protect both the company and its staff.Ìý
Clear written policies,ÌýongoingÌýemployeeÌýtrainingÌýand open communication all help reinforce accountability.ÌýPeriodically review user-access permissions, approvalÌýauthorityÌýand payment procedures to reduce the risk of unauthorized activity. YouÌýmay also want toÌýestablishÌýanonymous reporting mechanisms, such as whistleblower hotlines,Ìýthat allow employees to report concerns without fear of retaliation.ÌýPer the ACFE, 43% of occupational frauds were detected through tips —Ìýnearly threeÌýtimes more than any other detection method. OrganizationsÌýwithÌýformal reporting mechanisms also detected fraudÌýmore quickly and incurredÌýlower median losses.Ìý
BuildÌýstrongerÌýoversightÌýproceduresÌý
OneÌýpractical way to strengthen yourÌýcontrolÌýsystem isÌýto segregateÌýduties. Simply put, no employee should control all phases of a financial transaction. For example, the person who receives paymentsÌýshouldn’tÌýalso reconcile the bank account. Likewise,ÌýanÌýemployee who approvesÌývendor invoicesÌýshouldn’tÌýalso issue payments. Separating responsibilities makes itÌýeasier to detectÌýfraudÌýandÌýerrors.Ìý
If your business has limited accounting personnel,ÌýsegregatingÌýdutiesÌýcan be more challenging, makingÌýmanagement oversight even more important.ÌýRegularly review bank statements, canceled checks, payrollÌýreportsÌýand reconciliations.ÌýYou mightÌýalso outsource certain accounting functions to outside professionals toÌýhelpÌýstrengthen oversight.Ìý
Timely financial reporting is another criticalÌýcomponentÌýof effective controls.ÌýRecord transactionsÌýpromptly andÌýreconcileÌýaccounts regularly — notÌýjustÌýat year end.ÌýReview financial statements monthly or quarterly and investigate unusual fluctuations or unexpected variances. Budget-to-actual comparisons can be particularly useful inÌýidentifyingÌýirregularities.ÌýThe ACFE report found that organizations with management review controls experienced fraud losses that were 55% lower thanÌýthoseÌýwithoutÌýsuchÌýcontrols.Ìý
Also,ÌýcarefullyÌýmonitor adjustingÌýjournal entries and electronic transactions. Unauthorized adjustments or unexplained electronic transfers can sometimesÌýindicateÌýattempts to conceal improper activity.ÌýMore than half of fraud cases in the ACFE study occurred due to either a lack of internal controls (33%) or the override of existing controls (19%).Ìý
Continuous improvementÌý
Internal controlsÌýshouldn’tÌýremain staticÌý— they should evolve with your business.ÌýSome controls that worked when you were a start-up mayÌýno longerÌýprovide adequate protection.ÌýTechnology shiftsÌýand marketÌýchangesÌýmay also require you toÌýupdate your procedures.ÌýAÌýmidyearÌýreviewÌýcanÌýhelp youÌýevaluate whetherÌýyourÌýcontrols are functioning as intended andÌýidentifyÌýareasÌýforÌýimprovement. Even well-designed policies require ongoing monitoring to remain effective.Ìý
