Report Auditor's Format in Contract Pricing Including CAS & Allowable Costs Posted August 26, 2015 They're always going to request data in their format. However, if there's nothing in your contract that states this as a requirement, you should be fine in your own format. Do your best to provide the data elements that they've requested. I would recommend that you submit it in a format that can be modified and worked with (xls rather than pdf if that makes sense for you). Frustrating an auditor doesn't typically work out in the end for contractors. Best of luck!
