Receipts, invoices, and emails authorizing payment/showing proof of payment are all forms of supporting documentation which must accompany requests for payment/reimbursement in order to justify the expense.
Grant-related expenditures also require a Grant Summary Sheet with a detailed explanation of the expense.
For travel-related reimbursement requests, receipts are required for all transactions for which the traveler is seeking reimbursement except for meals and incidentals per diem, exact meals and incidentals expenses that are reimbursed at less than the per diem rate, and P-Card purchases less than $25.00. If applicable, cardholder transaction reports and per diem rate sheets must also be submitted. (VSC Policy 424).
The Missing Receipt Form is acceptable only as a last resort. It is expected that every effort will be made to obtain all necessary supporting documentation.
