Definition

Automated clearinghouse (ACH) payments are electronic payments that pull funds directly from your checking account. Instead of writing out a paper check or initiating a debit or credit card transaction, the money moves automatically.

Definition and Examples of ACH Debit

All depository institutions, such as banks and credit unions, in the U.S. are connected to the national automated clearinghouse network. This network enables these institutions to set up electronic deposits and withdrawals to and from customer accounts.

When you make an ACH debit payment from your bank account, the payee will initiate an electronic withdrawal directly from your account. This transaction does not involve paper checks or debit cards—the only information the payee needs is your bank account and routing number.

How ACH Debit Works

To pay with ACH, you’ll need to authorize your biller, such as your electric company, to pull funds from your account. This typically happens after you provide your bank account and routing numbers for your checking account and give your authorization by signing an agreement with your biller.

Note

In most cases, you'll use an online or paper form to establish ACH payments, but it might also happen over the phone.

Automatic payments

If you choose automatic recurring payments, your biller will pull funds from your account every time your bill is due. For example, you may allow a utility company to automatically charge your account for monthly bills. The biller initiates the transaction, and you do not have to take any action. This helps if you tend to get busy and forget to pay bills on time.

On-Demand Payments

You can also set up a link between your biller and your bank account without authorizing automatic payments. This gives you greater control of your account, allowing you to transmit payment funds only when you specifically allow it.

Pros and Cons of Using ACH Debit

Pros
  • Ease and convenience

  • No need to write checks

  • Save on postage

  • Easier payment tracking

  • Better for the environment

Cons
  • Less control

  • Exposing private information

  • Risk of mistakes

  • Potential for overdrafting

  • Forgetting to cancel services

Pros Explained

  • Ease and convenience: The main benefit of ACH is convenience. Once you set it up, you don't need to remember to mail payments. When you don't miss payments, you don't get hit with fees.
  • No need to write checks: You'll use fewer checks with ACH, and you won't have to remember to order them as often.
  • Save on postage: Not mailing your payments means you don't need to buy stamps, and ACH payments are often free (though some carry a small fee).
  • Easier payment tracking: Payee names appear on your bank statement, making it easy to keep track of transactions. You also avoid the risk that payments will be lost in the mail.
  • Better for the environment: Using fewer checks, stamps, and envelopes all adds up to less strain on the environment.

Cons Explained

  • Less control: In exchange for the convenience of ACH debit programs, you give up some control. If you automate payments, you have to remember to go online and stop payment before the withdrawal date.
  • Exposing private information: You hand over information about your bank account, including your account number, which gives the other party access to your account.
  • Risk of mistakes: A biller error may accidentally lead to you paying more than you should, and a large error could drain your account, causing you to bounce other payments and rack up fees.
  • Potential for overdrafting: You might overdraw your account if you don’t keep enough money available in checking to cover your automatic payments.
  • Forgetting to cancel services: You may forget what you’re paying for if you don’t actually see the bills come through, potentially resulting in continued payment for services that you no longer use.

Is ACH Debit Safe?

If you’re concerned about security, ACH is a safe way to pay. In some ways, ACH is safer than writing checks. You only need to expose your bank account information once to establish ACH payments, whereas paper checks expose your information every time you write one. Checks can also get lost or stolen, while ACH payments move money directly from your account to your biller’s account.

Even though problems are rare, you’re protected under federal law if any ACH errors or fraud do turn up in your account. The only catch is that you need to act fast and report those problems to your bank within 60 days.

Note

Consumer protection laws only apply to your personal accounts. Any business accounts you have are not as well-protected.

Unlike wire transfers, ACH payments are not immediate, irrevocable, and difficult to reverse. That makes it harder for a con artist to get your money and disappear overnight. ACH payments also generally require a U.S. bank account, which means that the recipient must provide enough identification for law enforcement to find them if the need arises.

Key Takeaways

  • ACH payments are electronic payments that pull funds directly from your checking account.
  • To set up ACH payments, you provide the payee with your bank account information and some form of payment authorization.
  • Payments can be made on demand or set up for automatic withdrawal on a regular basis.
  • ACH withdrawals are generally one of the safest ways to pay electronically.
