Any vendor of goods or services purchased by or delivered to an agency of the state whose payment is delayed beyond the forty-five-day limit and who has not been compensated by payment of interest as provided for in the Oklahoma State Finance Act may file a grievance with the Office of the Governor, who shall transmit it to the Director of the Office of Management and Enterprise Services. Upon receipt of such grievance, the Director shall pay the total amount of such invoice with interest as required, within fifteen (15) days, to remedy such grievance. If the Director determines that the invoice or interest should not be paid, such determination and the reasons therefor shall be reported to the Governor and the aggrieved vendor.
