A management system and method of assigning credit for unprintable images provided by a customer. When unprintable frames are submitted for processing, such as scanning, printing or storage, the method allows the photofinisher to keep track of the number of image submitted for processing and assigns credit for to the customer's account for unprintable images. As an example of redeeming such credit, when the number of unprintable images equals a pre-set criterion, such as the number of frames in a roll, a free roll of film could be issued to the customer.
