The first month of same-day ACH appears to have come in like a lion and gone out like a lamb.

Despite grumbling about fees and fraud concerns leading up to the Sept. 23 addition of two new same-day settlement windows for credits on the ACH network, the change has largely gone as expected, according to NACHA – The Electronic Payments Association. The ACH network is the backbone of the electronic payments system, and in the second quarter of 2016 it handled 5.05 billion transactions worth $10.9 trillion – a year-over-year increase of 5.6%, according to NACHA.

"It was a smooth implementation. The industry did a lot of work getting ready; there was a ton of education and communication available," NACHA Senior Managing Director Michael Herd told CU Times. "The processor community also got really involved in working with their customers. From our perspective, the implementation, the go-live date, went extremely well."
