The ACH Network posts a Big Quarterly Gain As B2B Payments Soar.

The nation’s automated clearing house network handled 7.5 billion transactions in the fourth quarter of 2021, up 6.1% over the same period in 2020, Nacha reported Thursday. The growth was driven largely by gains in health-care and business-to-business payments, as well as robust increases in same-day ACH, the network’s faster-payments service.
