Petty Cash Reimbursements

Department contact: Brianna Divine, 3-1678. Scan and email all forms/receipts to

Updated: 9/3/2021: If you are photographing your receipts with your phone, you must use the Adobe Scan app. JPG quality is unacceptable for records retention purposes. Alternatively, use a department copier to scan to email (no copy code needed).

  • Use natural light, next to a window is good.
  • Center your phone/camera directly over the paperwork, this is not the time to get fancy with angles. 
  • Zoom in enough so the paperwork fills the whole screen, yet doesn't cut off important information.
  • For store receipts with reward info at the bottom that takes up most of the recieipt? We don't need it, crop that out.
  • Save your original receipts just in case.

Use the Petty Cash Voucher for all non-travel, UW-business reimbursements. (Use the Travel Authorization / Reimbursement portal for travel expenses)

Documentation  A  And   Documentation B

Bank statement

Packing slip



Print-out of a picture of the receipt (use your phone)

If the missing receipt purchase is over $75, and you cannot provide these documents, then the expense cannot be reimbursed.

Fleet Services Gas

  • Turn in gas receipts for UW Fleet Services vehicles directly to the Fleet Services office.
