ACH payments are financial transactions handled through what is called the Automated Clearing House (ACH). ACH is an electronic network that processes very large volumes of transactions in the United States. The network through which these payments are made is highly reliable and efficient, and it is used for a variety of purposes. Trillions of dollars are processed through the network every year in the U.S.

Both the U.S. government and the private sector use ACH to conduct business. ACH payments include direct deposit of paychecks and tax returns, direct payment of consumer accounts, business-to-business payments, and tax payments. The Federal Reserve and the Electronic Payments Network (EPN) act as ACH operators. In other words, all transactions pass through one of these two operators.

The Federal Reserve banks in the U.S. are, when taken together, the largest ACH operator. In 2002, for example, they processed about 60% of commercial transactions, while the EPN processed the other 40%. Often the Federal Reserve and the EPN rely on one another to complete the processing of some transactions where either the originator or the recipient is not their customer.


A typical transaction will play out in the following way. Once the receiver authorizes a transaction to be made, the originator of the transaction sends the transaction data to the Originating Depository Financial Institution (ODFI). This might be, for example, the originator’s bank. The ODFI then transmits the data to an ACH operator, usually the Federal Reserve or EPN. The operator acts as a sort of middleman or mediator between the originator and the receiver.

The operator sends the file with the transaction data to the Receiving Depository Financial Institution (RDFI) which, put simply, is the receiver’s bank. The RDFI then makes the funds available to the receiver, and modifies the receiver’s account statement accordingly. From the perspective of the average consumer, this whole process goes on unnoticed in the background. Because of this, most Americans have probably made or received ACH payments without even realizing it. For example, every time someone pays for consumer goods with a debit card, or pays a bill online with his checking account, that transaction must go though an ACH operator.

The system is governed by the operating rules of NACHA-The Electronic Payments Association — it was formerly called the National Automated Clearing House Association, leading to the odd acronym. Apart from governing the ACH network with its thousands of members, NACHA is also responsible for ensuring the quality of transaction data in the system, and developing new methods of payment.

How do I know if my payment got through?

@ ValleyFiah & Highlighter- The ACH electronic payment trap! There are two things that I rarely ever give social security number, and my bank account number. There are too many thieves to take the chance of trusting someone to be honest.

@ Highlighter- Don't feel too bad. I have been victim to fraudulent ACH payment processing a couple of times. It is often one of those situations where you can take it to small claims court or take it like a champ. It’s usually not worth taking to court.

When it happened to me, I checked the BBB rating of the business, and it was an F (I bought my wife a recurring membership at a nearby tanning salon). People had filed complaints for similar situations.

Now I never give out bank account information unless it is to pay a loan from a bank, or a credit card. I always use my debit or credit cards for these types of things. It’s much easier to cancel a card, and most cards now offer some type of reward on purchases.

There is a risk to paying for goods and services through ACH payment. I learned this the hard way. I bought a monthly membership to a new gym in my area, using ACH as a payment method rather than using a credit or debit card. I canceled my membership a few months after I signed up (the gym was always filthy and shady things were going on during the later hours).

After I canceled, I was being charged for my gym membership for months on end. I had filed all of the necessary paperwork, kept copies for my own records, and attempted to speak with the owner and manager on numerous occasions (oddly enough they were always gone when I

stopped by or called).

Long story short, I tried to have the bank stop payment on the transaction, but because I signed up through ACH and they had my account number, the only way I could get the charges to stop was to close my account and open a new one.
