S.C. Code Ann. § 4-13-80

Nothing in this chapter shall be construed to prevent the governing body of any county from disallowing any account, in whole or in part, when so rendered and verified, if it appears that the charges are incorrect or that the services or disbursements have not, in fact, been made or rendered, nor from requiring any other or further evidence of the truth or propriety thereof. No allowance or payment beyond legal claims shall ever be allowed. And the governing body of the county may refuse to audit or allow any claim or demand whatsoever unless made out and verified in the manner herein specified.
