What documentation do I need if I will be combining business travel with personal travel?

When combining personal travel with business travel, only those expenses directly related to the business travel can be paid/reimbursed by the university. Travelers must ensure that all business related and vacation expense variances are clearly documented and available for audit review. It is best practice to keep all business related expenses separated when possible; this ensures that documentation is as clear as possible. When this cannot be done (e.g. Airfare), cost comparisons should be done to show the pricing differences as if only business time was included. Cost comparisons should be conducted at the same time the expenditure of funds occurs and must be clearly documented and available for audit review. Expenses such as parking and Per Diem will be prorated and limited to only the business travel date/time.
