(a) A state agency shall:
(1) inspect and evaluate at the time of receipt all goods or services that the agency receives to determine whether the goods or services comply with the contract under which they were purchased; and
(2) certify, if true, that the goods or services comply with contract requirements and that the invoice for them is correct.
(b) If state law requires that a payment for the goods or services be made on a warrant drawn or an electronic funds transfer initiated by the comptroller or a state agency with delegated authority under Section 403.060, promptly after the later of the receipt of the invoice or the receipt of the goods or services, the agency shall send to the comptroller the certification, together with the financial information and purchase information provided by the invoice and purchase voucher, on a form or in the manner prescribed by the comptroller.
(c) The comptroller by rule may require that purchase information be sent directly to the comptroller in circumstances under which the comptroller considers it necessary.
