Question about documentation vs customer perception

Customer finds that it is waste of effort in preparing documents adhering to the processes. He just pays for the hours for the time spent on product/Services. Convincing him has gone down the drain. Being CMM level 5 company, the organization requires documents. The development team says if customer does not want, why should they waste time on it? How do i handle this situation?
