This bill would require contracting agencies to notify contractors in writing of any disputed portion of an invoice and the basis for the dispute no later than ten business days after the invoice received or acceptance date. Where any portion of a proper invoice is disputed, the contracting agency would be required to pay the undisputed portion by the required payment date. The bill would also require contracting agencies to notify contractors of any documentation deficiency that prevents an invoice from constituting a proper invoice, and to treat any sufficiently documented portion of such invoice as a separate proper invoice for purposes of determining the required payment date.
