Karen, a friend of yours, recently started her own business, The Bike and Boulder Company (B&B). B&B specializes in the sales of mountain bikes and rock climbing equipment. Karen is putting the finishing touches on her company policies and procedures. She knows you are taking a fraud class and asks you to review what she has completed thus far. You quickly notice that Karen has neglected to address fraud and fraud prevention in her policies and procedures. What policies and procedures would you suggest Karen implement to prevent and detect fraud at B&B?
