I?ll break my answer in 4 parts for your question.
1. What is ACH?
Automatic clearing house (ACH) is a nationwide electronic funds
transfer (EFT) system that provides for the inter-bank clearing of
credit and debit transactions and for the exchange of information
among participating financial institutions.
ACH is one of the groups of processing institutions that have
networked together to exchange (clear and settle) electronic
According to Computer world magazine,
?The Automated Clearing House is a secure, private electronic payment
transfer system that connects all U.S. financial institutions. Direct
paycheck deposits and debit card purchases are two examples of
electronic fund transfers that go through this network.?
?Executing ACH payments is cheaper and faster than processing paper
checks, both business-to-business and business-to-consumer e-commerce
activities are becoming ever more dependent on the ACH system, thus
forcing it to evolve.?
A little history on ACH-
The ACH was conceived in the early 1970s, when it seemed that the
increasing volume of paper checks used by businesses and consumers to
pay their bills would eventually exceed the ability of the existing
computer systems to process and sort the checks efficiently. The
Federal Reserve participated in the early discussions and offered to
provide the computer systems necessary to process and settle the ACH
items between the depository institutions. In 1974, the regional ACH
associations formed NACHA to coordinate the establishment of rules to
facilitate the nationwide clearing of ACH payments.
The National Automated Clearing House Association (NACHA) develops the
rule and the standards about ACH transactions.
?In 2000, over 4.8 billion payments with a total value of more than
$12 trillion were processed by ACHs through the Federal Reserve
System. Typical ACH payments include salaries, recurring bill
payments, and Social Security benefits?
2. Who can originate the transfer of funds from one account to another
OR How ACH process works?
An ACH entry starts with a Receiver authorizing an Originator to issue
ACH debit or credit to an account. An Originator can be a person, the
gas company, your local cable company, or your employer. Depending on
the ACH transaction, the Originator must receive written (ARC, POP,
PPD), verbal (TEL), or electronic (WEB) authorization from the
Receiver. Once authorization is acquired, the Originator then creates
an ACH entry to be given to an Originating Depository Financial
Institution (ODFI), who can be any financial institution who does ACH
origination. This ACH entry is then sent to an ACH Operator (usually
the FED) and is passed on to the Receiving Depository Financial
Institution (RDFI), where the Receiver's account is issued either a
credit or debit depending on the ACH transaction.

3. How much ACH cost?
A single ACH transaction may cost from 2.5 to 25 cents and this is one
of the important reasons why ACH has become so popular payment
mechanism. ACH transactions cost considerably less than wire payments.
4. How to setup ACH system?
From your question, it sounds to me that you are asking about how to
be an ACH. For this, you need to contact all the banks, merchants and
financial institutions with which you want to setup your ACH process.
?Simply contact the company in which your debit or credit will
originate to see if they participate in the ACH program. Your
employer, power company, insurance company, telephone company, and
your cable television company are just a few of the firms that may
participate in the ACH program.?
