We at knoxpayments.com support NACHA's push for same day ACH. We have a product called "Knox Assured ACH" which does what is described in this conversation - sends a message to the receiver of the funds as soon as the payment is done to "assure" them they will get their funds. We give a 100% guarantee instantly. Same day ACH will help us do this even more efficiently and we're excited about the prospect!
