ACH A.L.E.R.T. allows financial institutions to provide protection against incoming unauthorized ACH transactions to both business and consumer accounts. As ACH transactions arrive, actionable alerts are sent to account holders via their preferred method. Account holders can quickly and easily identify companies as "trusted" and add them to their approved list as ACH transactions are presented to pre-authorize future payments and prevent unnecessary alerts. The self-service, customer engaging and automated dispute resolution capabilities of ACH A.L.E.R.T. have financial institutions discontinuing use of traditional ACH debit blocks and filters. The result, more adoption, less operational work, happier customers and more revenue!
