One effective strategy for controlling employee expenses is to establish a comprehensive expense policy. The policy should define acceptable expenses, set spending limits, and provide clear guidance on acceptable practices. Encourage employees to adhere to the policy, and require them to submit evidence such as receipts for any claimed expenses. Regular audits can also be conducted to track errors and potential fraudulent activities. By implementing a clear and consistent expense policy, businesses can better manage employee expenses and ensure they align with the company’s overall financial objectives.
