Permission, as well as an account number, must be obtained from the major professor before any purchases for a project are made with University funds. All receipts should be given to the Departmental Bookkeeper for accounting, and should include a chargeable account number (available from the major professor), the graduate student’s name (legibly), and, if not provided by the vendor, a brief description of the item(s) purchased. Note especially that the purchaser is responsible for ensuring that the purchase cost does not include sales tax, as correcting that after the fact can be very onerous.
