NACHA comes out with rule changes all the time. We are using the standard agreements (RDFI/ODFI) for ACH transactions which are availalbe from NACHA. I would like to know how you go about amending the agreements when some rather significant rule comes out and you feel it should now be included in all your agreements? (i.e responsibility for monetary penalties imposed by NACHA). Do you send out a new agreement, an amendment page? How often do you revise your agreements???
