Before we dive into understanding common ACH banking terms, we first need to understand the meaning of ACH. 

What Does ACH Mean in Banking Terms?

The Automated Clearing House (ACH) Network is a digital network used for financial transactions by businesses and consumers in the United States. The ACH network was founded on the principals that U.S. employees should be able to trust that they will be paid on time by their employers. 

The ACH Network was created by NACHA (National Automated Clearinghouse Association). By creating a nationwide system for electronic fund transfers, NACHA could help ensure the timely payment of employees. The ACH Network has evolved over the last twenty years to expand its purpose. 

Below are some of the most commonly used terms and acronyms within the ACH network. By mastering these definitions, you can begin to master the ACH Network as a whole system.
