What is ACH?

ACH stands for Automated Clearing House. The Automated Clearing House network provides the mechanism for ACH transfers¹.

ACH history

The ACH network started in the 1970s. Banks across the US came together to find ways to improve payment systems. The growing volume of paper checks in use was a shared concern.

The solution was an electronic network for payments between banks. Consistent standards were developed, and the ACH network was born.

ACH today

Today, Nacha manages the ACH network. It is used to transfer money between bank accounts all over the US. ACH is the system behind Direct Deposit, Direct Payments, and several other methods.

In 2019, the ACH network processed 24.7 billion payments totaling over $55.8 trillion². Chances are you have used ACH without even realizing it!

What is ACH payment?

An ACH payment is an electronic transfer between bank accounts that is handled by the ACH network. This payment can be to or from a business, individual, or government account.

ACH payments are different from wire transfers. These are direct payments between bank accounts, without intermediaries. They are also different from payments using other networks, such as VISA or Mastercard.

You may also see ACH payments referred to as ACH transfers or ACH transactions. These are all the same!

How does an ACH work?

ACH transfers work by grouping transfers between banks together. Once placed, transactions are checked and then held by the bank for batch sending. The transactions are then sent in bulk.

ACH transfer types

There are two types of ACH transfer:

ACH direct deposits

Direct deposits are payments from organizations to an individual. If you have a regular payment made to your bank account from your employer, chances are it is an ACH direct deposit. 93% of salaries in the US are paid this way³.

Common ACH direct deposits include:

  • Payroll/salary
  • Government benefit payments
  • Bank interest payments
  • Dividend payments
  • Pension payments
  • Tax rebates

ACH direct payments

Transactions that make payments, to either a company or another person, are known as direct payments. If you are putting money into another account, this is a direct payment.

There are two types of ACH direct payments:

ACH credit payment. This is a payment made straight to the bank account of another person or company. It’s what you’ll use when paying family or friends, or one-off invoices.

ACH debit payment. This is an instruction that allows a company to take money from your account. It can be set up for regular payments, such as recurring bills.

What is the difference between ACH and Direct Deposit?

Direct deposits are an important part of the ACH network. They cover many regular payments across the US. If you receive money from a company or the government, this is a direct deposit.

But whenever you make a payment to another person or company, you are looking at an ACH direct payment.

Is ACH payment safe?

Transferring money is often a worry. No-one wants to see payments go missing.

The ACH network and payments are one of the safest transfer methods. Transmitted data is encrypted with bank-level encryption⁴. This reduces the chances of it being compromised.

Importantly, you can reverse an ACH payment. If you later notice an error or suspect fraud, the payment can be tracked and reversed. This is a great feature – and not something you can do with wire transfers.

Pros and cons of ACH for individuals

ACH transfers have several advantages for individuals:

  • Cheap way to transfer funds between US bank accounts
  • Often free to make and receive transfers
  • Safer than a wire transfer, as you can reverse payments
  • Setting up regular transfers helps avoid missed or delayed bill payment

But ACH is not perfect! There are also some drawbacks to think about:

  • Transfers can take up to 4 days
  • There are cut-off times to make transactions for that day - missing this will add to the transfer time
  • Limited in use for transferring overseas
  • Banks may have limits on the amount sent per account (this can be per transaction, daily or monthly)
  • The law limits transfers from savings accounts to six per month

Pros and cons of ACH for businesses

ACH is very popular for business for several reasons:

  • Free, or low-cost, transfers even for high volumes
  • Easy way to manage bulk payments, such as payroll
  • Lower transaction costs than other networks (such as credit or debit card, or PayPal payments)
  • Higher customer retention, as bank accounts are more stable than cards

Some disadvantages businesses need to consider include:

  • Limited overseas use is a problem for international businesses
  • Not ideal for high volume, time-critical payments

ACH transfer costs

Cost is the main advantage of ACH transfers, especially when compared to a wire transfer. There are usually no fees for receiving payment.

ACH transfers are often free to send for the individual, although some banks charge up to around $3⁵. You can check with your bank to find out if there is a fee in advance.

Wire transfers are much more expensive. Domestic wire transfers cost around $15 to $30, and internationally this can be as high as $50⁶.

ACH transfer times

ACH transfers are not instant. Transfer time varies between 1 and 4 business days. They are cheap and secure, but can be slow!

Nacha standards state that debit payments should be processed by the next business day. And credit payments within two business days.

The actual transfer time depends on the financial institution. It is often 1-2 business days but can be up to 4 days.

ACH same-day processing

ACH has recently improved transfers with same-day processing, for both debit and credit transfers⁷. These are available from some banks and may have a higher cost. Although processing is same-day, delivery is usually the next business day.

As with all ACH transfers, there is a deadline to confirm same-day processing. Nacha is planning to extend this deadline by two hours in 2021 (to 4:45 pm ET)⁸.

International ACH transfers

ACH transfers to overseas accounts are possible but are not yet widespread.

If you are looking to make a transfer, look for a bank offering International ACH Transfer. This is different from International ACH Transaction (IAT) - which is more about bank reporting. Banks may mention IAT even when they do not offer international transfers.

Wire transfers are more widely used for international transfers. These are usually handled by SWIFT (Society for Worldwide Interbank Financial Telecommunication). But fees are high, and there are extra costs associated with the exchange rate used.
