A colleague asks for your advice on what to do. She is the sales manager for a food catering business. One of her customers places an order on December 30 to be delivered the next day for a New Years Eve party. The customer asked her to date the invoice for January 1 for income tax purposes. Your friend has already met the sales quota for the year, so booking the sale in the next year will get her off to a good start on new goals. Is this an appropriate request? Why or why not?
