A control weakness in the oversight of credit sales is evident when the sales department is responsible for determining the credit ratings of customers. This structure can lead to a conflict of interest, as the sales department may be motivated to approve higher credit limits or overlook credit standards to increase sales figures. This undermines the objectivity and effectiveness of the credit approval process, which should ideally be handled by an independent department such as credit control to ensure unbiased evaluation.References:
