Okla. Stat. tit. 74, § 74-85.44B

A. Payment for products or services pursuant to a contract

executed by a state agency, whether or not such state agency is

subject to the Oklahoma Central Purchasing Act shall be made only

after products or services have been accepted as satisfactory. This

section shall not prohibit the payment of membership dues or payment

for subscriptions to magazines, periodicals or books or for payment

to vendors providing subscription services.

B. If the State Purchasing Director approves an acquisition

from the federal government or agency and determines that the

regulations of the federal government or agency handling the

acquisition require that partial or full payment be made before the

acquisition will be delivered, the State Purchasing Director, upon

requisition by the requesting party, shall have a state warrant

drawn against the funds of the acquiring state agency payable to the

United States of America or its proper agency. The warrant shall be

in such amount as may be necessary to meet the terms and conditions

of the acquisition without requiring a certificate showing that the

acquisition has actually been delivered to the state agency in whose

behalf the purchase is being negotiated.
