Here are a few steps to get you moving in the right direction.The safest way to prevent stealing by employees: Hire honest peopleIt might sound obvious, but your best defense against employee theft is to hire honest employees. Thoroughly screen all job applicants by requiring a detailed application, checking references, and conducting a face-to-face interview. If you'd like to go even further, you can require a criminal background check for all potential employees, and in some states, depending on whether the employee will be handling money, you can require a credit check. Sometimes the requests themselves will cause an undesirable candidate to move on.Internal controls aid in preventing employee theftA few simple policy changes and adjustments to your business's everyday operations could make employee theft much more difficult. Consider the following:Duties such as issuing checks, making deposits, managing inventory, and reconciling accounts should be kept separate. Require a second signature for disbursement checks over $500.Individuals with access to company books or purchasing/paying duties should be monitored. Such employees should be granted only as much access as they require to perform their duties.Rotate tasks among employees whenever possible.Carefully review all journal entries and be alert to large numbers of unnecessary entries.Consider hiring an outside CPA firm to perform an annual audit.Require employees to use passwords to access computers or networks and have employees change their passwords on a monthly basis.
