An allowable business expense is an expense or a transaction that the university, a faculty, staff, or student incurs on behalf of the university in exchange for goods or services. Payment of an allowable business expense is ultimately the responsibility of the university. Only original itemized receipts are acceptable for reimbursement. For out-of-pocket expenses, SU does not cash out gift cards, airline mileage; wallets; or rewards points used for payment. Reimbursements at any value need to have the accompanying receipt or missing receipt affidavit. A list of attendees and the business purpose are required when expense includes payment for individuals in addition to the requestee.
