N.C. Gen. Stat. § 147-86.22
The State Controller shall establish policies that allow accounts receivable to be payable under certain conditions by electronic payment. These policies shall be established with the concurrence of the State Treasurer. In addition, any policies that apply to debts payable to or through the office of a clerk of superior court or a magistrate shall be established with the concurrence of the Administrative Officer of the Courts. The Administrative Officer of the Courts may also establish policies otherwise authorized by law that apply to these debts as long as those policies are not inconsistent with the Controller's policies.
A condition of payment by electronic payment is receipt by the appropriate State agency of the full amount of the account receivable owed to the State agency. A debtor who pays by electronic payment may be required to pay any fee or charge associated with the use of electronic payment. Fees associated with processing electronic payments may be paid out of the General Fund and Highway Fund if the payment of the fee by the State is economically beneficial to the State and the payment of the fee by the State has been approved by the State Controller and State Treasurer.
The State Controller and State Treasurer shall consult with the Joint Legislative Commission on Governmental Operations before establishing policies that allow accounts receivable to be payable by electronic payment and before authorizing fees associated with electronic payment to be paid out of the General Fund and Highway Fund.
A payment of an account receivable that is made by electronic payment and is not honored by the issuer of the card or the financial institution offering electronic funds transfer does not relieve the debtor of the obligation to pay the account receivable.
The State Controller shall negotiate a contract with a third party to perform an audit and collection process of inadvertent overpayments by State agencies to vendors as a result of pricing errors, neglected rebates and discounts, miscalculated freight charges, unclaimed refunds, erroneously paid excise taxes, and related errors. The third party shall be compensated only from funds recovered as a result of the audit. Savings realized in excess of costs shall be transferred from the agency to the Office of State Budget and Management and placed in a special reserve account for future direction by the General Assembly. Any disputed savings shall be settled by the State Controller. This paragraph does not apply to the purchase of medical services by State agencies or payments used to reimburse or otherwise pay for health care services.
