What Is An ACH Withdrawal And How Does It Work?

See what an ACH withdrawal is, how it works, and how to stop one if you ever need to.

Key takeaways

  • Recognize an ACH withdrawal as an authorized electronic pull from your bank account, also known as an ACH debit.
  • Authorize ACH withdrawals only for vendors you know and trust, since they can pull funds from your account on a schedule.
  • Choose ACH to keep payment costs low, as it is far cheaper than wire transfers for everyday business payments.
  • Review your ACH charges regularly and contact your bank right away to dispute any withdrawal you did not authorize.

What is ACH?

ACH stands for “Automated Clearing House.” If you’re wondering what an ACH payment is, it’s a type of bank transfer that lets businesses send and receive money electronically, also referred to as an ACH EFT. The network is comprised of member financial institutions (AKA clearing houses) and is governed by Nacha, which ensures its compliance and security.

How popular is ACH?

Thanks to its cost-effectiveness and the fact that it can be done entirely online, ACH is among the most popular options for domestic transfers in the U.S—for both businesses paying and vendors receiving funds.

While ACH transfers can now also be used for international transactions, it is not yet supported by all banks, making them less accessible for this purpose. Nevertheless, in 2024 the ACH Network processed 33.6 billion payments valued at $86.2 trillion, up 6.7% over the prior year, reports Nacha. Business-to-business payments were one of the biggest drivers of that growth.

The differences between ACH and wire transfers

ACH is similar to other payment methods. We’ve discussed the difference between ACH and SWIFT in a different blog post, but what’s the difference between a wire and ACH transfer?

While wire transfers are direct transfers between one bank account to another, ACH payments go through the Automated Clearing House, thus creating several differences. Here are the key ones:

International transfers

  • ACH can be used internationally, but it’s not yet supported by all banks, so your ability to perform this might vary.
  • International wire transfers have been available for a long time, making it easier to initiate such a transfer.

Cost

The Clearing House performs ACH transfers in bulk, which means it’s less costly. Wire transfers are done on a case-by-case basis, and you see the difference in the price.

Use cases

To sum up, let’s review which payment option is best for popular use cases.

  • Best use cases for ACH: Small transactions (because wire transfers are too expensive for those) and recurring payments (for long-term efficient budgeting).
  • Best use cases for wire transfers: Immediate transfers, international transfers, and especially bulk transfers. If you’re getting multiple payments from the same vendor at the same time, ACH doesn’t let you distinguish which part belongs to which invoice. Everything is paid together by the Clearing House. Wire transfers can easily be done one by one. And, of course, if the transfers are big enough, the more expensive wire transfer fee might not make a difference to you.

If you need a deeper explanation, we’ve got you covered. Here’s a deeper dive into how ACH differs from a wire transfer.

More specifically, what is ACH withdrawal?

An ACH withdrawal is an electronic pull payment that lets an authorized party collect funds directly from your bank account. Here’s a simple way to picture it.

Say you got coffee with a colleague who left their wallet at the office, and you ended up covering the bill. The colleague now has several ways to pay you back:

  • Buy you coffee next time.
  • Hand you cash.
  • Send you a payment via a mobile app or bank transfer.
  • Tell you to reach into their purse and take the appropriate amount when you get back to the office.

That last option is much like an ACH withdrawal. The payor gives the recipient permission to pull money directly from their account.

Only grant that permission to people and organizations you know well and trust.

What else is ACH withdrawal called?

Even now that you understand the ACH withdrawal meaning, it’s easy to get confused. That’s because this process has additional names. If you hear…

… know that it’s the same as ACH withdrawal.

How does ACH withdrawal work?

An ACH withdrawal takes three main steps:

Step 1: Authorize the ACH withdrawal

The payor authorizes the recipient to withdraw funds directly from her or his account.

Step 2: Request the withdrawal

The recipient of the payment sends a withdrawal request for the open balance to the payor’s bank. They do it through the ACH network.

Step 3: Processing the withdrawal

The bank approves and processes the ACH payment, transferring it to the recipient.

You’ve probably used ACH withdrawals without even knowing it

Want an example? Have you ever signed up for an app using your bank account? In many of these apps, validating the account means you’re giving the app authorization to withdraw funds in correlation with the payments you make.

How long does an ACH withdrawal take?

So, how long does an ACH transfer take? Standard ACH withdrawals usually take a few business days, because the network verifies each transfer. You can often pay a small fee to speed it up with same-day ACH. If you’re wondering how long a Melio payment takes, it depends on the payment method you choose—standard ACH, same-day ACH, credit card, or wire.

Are ACH withdrawals safe?

ACH withdrawals are generally safe. They run on the Nacha-governed ACH Network, and debits are far less targeted by fraud than paper checks.

As ACH payments grow in popularity with businesses, they also grow in popularity with scammers, so it’s fair to ask: are ACH payments safe?

According to the 2025 AFP Payments Fraud and Control Survey, checks remain the payment method most targeted by fraud, with 63% of organizations hit by check fraud, while ACH debits are far less exposed.

So, is ACH safer than wire? According to that survey, checks are by far the most-targeted payment method, so ACH debits carry meaningfully lower fraud exposure than paper checks.

All in all, while some risk always exists, most organizations that use ACH withdrawals are never hit by fraud.

When is ACH withdrawal used for B2B transactions?

ACH withdrawal is a convenient way to set up recurring payments to vendors with whom you have an ongoing relationship. It’s especially useful when you’re paying the same vendor periodically, but the amount varies each time. For example:

  • Utility bills
  • An accounting firm’s billable hours
  • Recurring purchases, such as produce, office supplies, and paper products

Using ACH withdrawal allows your vendor to automatically charge you with the up-to-date sum each month with no additional action required on your part. Remember, preferably, this needs to be a vendor who you:

  • Have worked with for a while
  • Trust wholeheartedly
  • Know has a very credible reputation in the industry

What are the pros and cons of ACH withdrawals for businesses?

We’ve already established that an ACH withdrawal can be a useful tool in your payment method belt. Still, it’s important to assess the benefits and risks associated with it, before deciding to use it for your business.

Pros of using ACH withdrawal

ACH withdrawals offer a number of ACH benefits for small businesses—from convenience and affordability to security and automation.

  • Convenience. Instead of manually sending a payment each month, your vendors can automatically charge you the right amount periodically. You don’t have to do anything.
  • Price. Unlike wire transfers, ACH transfers are relatively cheap, so you’re not spending too much money to pay the bills.
  • No maintenance required. Once you set up and authorize an ACH debit to your vendor, the payments go through regularly according to the terms you agreed upon. You can always revoke the ACH withdrawal authorization.
  • No late payments. Since there’s no need to take additional action for the payment to go through, you’re never at risk of accidentally skipping a payment.
  • Safety. The several days it takes for an ACH withdrawal to get processed are an opportunity for you and your bank to catch any fraudulent or erroneous activity, and reverse the payment if needed.

Cons of using ACH withdrawal

While ACH withdrawals are typically safe, and Nacha is constantly working to ensure this safety, there are ACH fraud concerns to take into account when choosing to pay via an ACH withdrawal:

  • Breach of trust. When you authorize an ACH withdrawal, you’re essentially giving your vendor permission to extract money from your account. This freedom can be misused.
  • Compromised credentials. As with all ACH transactions, an ACH withdrawal requires you to provide your vendor with your bank account number and routing number. If these credentials get into the wrong hands, they can be used to facilitate ACH fraud. This can happen even if the vendor is reliable, but gets hacked (or hires that one wrong person, who’s not as reliable as the vendor hoped).

To decrease the chances of fraudulent charges:

  • Only trust reliable vendors for ACH withdrawals. Ideally, these are vendors that have an ongoing relationship with you and a very reputable name in the industry.
  • Go over your charges periodically to see if you detect anything out of the ordinary in time to reverse the payment.

How to make an ACH withdrawal?

The ACH payment process is simpler than it sounds.

  • Step 1: You send the request to the bank
  • Step 2: The bank submits the request to the ACH network
  • Step 3: The ACH network processes the withdrawal
  • Step 4: The payment from your payor is deposited in your account

What do you need for an ACH payment?

When you want to get an ACH payment, you need to provide:

  • Name
  • Account number
  • Routing (ABA) number
  • Payment amount

Unauthorized ACH withdrawals: What can you do?

The ideal situation is catching the unauthorized ACH withdrawal before it’s transferred to the receiver. Some ACH transfers take several days, yet some do happen faster.

In any case, in the U.S., the Consumer Financial Protection Bureau (CFPB), a U.S. government agency, recommends notifying your bank or credit union, even if the transaction has already been completed.

How to cancel an ACH withdrawal?

You can cancel an ACH withdrawal by notifying your receiver, your bank, or both

Take into consideration that you can stop future withdrawals, but if a vendor already performed agreed-upon services, paying for that will likely still be required.

If it’s a vendor you no longer trust, it’s likely best to cancel the ACH withdrawal permission, make a one-time manual transfer and close this chapter.

Wait, there’s another type of ACH transfer?

There are two main types of ACH bank transfers: ACH withdrawal (also known as ACH debit) and ACH credit—you can learn more about ACH debit vs ACH credit here.

We discussed what ACH withdrawal means, but ACH credit is actually the more common kind of ACH.

ACH credit works just like a regular bank transfer. It’s initiated by a payor sending a single payment directly to a recipient’s bank account. Some of its wide-ranging uses include:

  • Governments that pay social benefits to citizens
  • Companies that pay vendors for goods and services
  • Employers that pay salaries to employees

ACH credit has been embraced by digital accounts payable tools, including Melio, contributing to its popularity.
