What is the best method for getting a vendor paid?
If the transaction is less than $3,000, the vendor accepts credit cards, and the purchase is not equipment use your departmental credit card. If the vendor does not accept credit cards or if you are making a prepayment or no value will be added by a purchasing agent you can use a non-po voucher and invoice. For transactions that are greater than $3,000, blanket orders, contracts, maintenance, if vendor requires a purchase order or for departmental tracking purposes you need to fill out a requisition.
