Nacha
Nacha (the National Automated Clearing House Association) is the organization that governs the ACH network and writes the Nacha Operating Rules that every bank and originator using ACH must follow. Those rules define authorization requirements, transaction timing, and the procedures for returns, reversals, and disputes of ACH payments. Nacha is a private rule-making body, not a government agency.

What is an ACH authorization form?
An ACH authorization is your written permission letting an organization move money to or from your account electronically through the ACH network. A debit pulls money out; a credit pushes it in. Under Nacha rules, a consumer debit authorization must be written, signed, and clearly state the amount, timing, and how to revoke it.
How to stop an automatic ACH payment you authorized
To stop a recurring ACH payment you authorized, tell the company in writing that you revoke your permission to debit your account, and tell your bank too. Under Regulation E you can also order the bank to stop payment on the preauthorized transfer by notifying it at least three business days before the next debit.
