When an expenditure authorized to be made by any state department, body or officer is of such a nature as to require payment in advance of performance or delivery, then the right of the officer to obtain such service or property on behalf of or in the service of the state shall constitute a claim against the state to be presented and allowed as are other claims. The board of examiners may, in its discretion, prescribe policies and procedures with respect to the filing and allowance of such claims and the subsequent accounting therefor. Any money obtained upon such claim and not expended on behalf of or in the service of the state shall be repaid by the claimant to the state.
