Developed by the National Automated Clearing House Association (Nacha), Accounts Receivable Conversion modernizes check processing for high-volume receivables billers (such as utilities, telecommunications, insurance carriers, and healthcare systems). Under ARC rules, when a consumer mails an original paper check with a payment coupon to a designated lockbox or billing address, the optical scanning hardware captures the magnetic ink character recognition (MICR) routing and account numbers along with the check amount. The physical paper check is converted into an electronic Standard Entry Class (SEC) code 'ARC' debit transaction, processed through the ACH network for next-day or same-day clearing, and the original paper check is systematically voided and destroyed within contractual retention periods. ARC processing dramatically accelerates ledger cash application, reduces bank lockbox handling costs, and eliminates float compared to traditional physical check clearing.
