Three new enhancements to Same Day ACH are coming. The first takes effect in just a matter of months—September 20, 2019, to be precise.
To help with preparations, Nacha has created three new guidance sheets. Each is a two page PDF available for download. There are versions for Originating Depository Financial Intuitions (ODFIs), Receiving Depository Financial Intuitions (RDFIs), and Processors.
You will also find them in our Same Day ACH Resource Center, which has a wealth of helpful information.
