Audit Working Paper Format 1. The diversity of audit assignment prevents the establishment of a single system or design of working papers to be used. Therefore, a uniform working paper format may not be used but work papers for functional areas such as cash receipts should display conformity in various types of audits. 2. Work papers may be in the form of paper, tapes, disks, diskettes, films, etc. There should be backup copies of electronically generated working papers. The backup copies should not be stored with the original copies.
