What is an ACH transfer?
An ACH transfer is an electronic bank-to-bank payment in the United States that moves through the Automated Clearing House (ACH) network in batches, rather than one transaction at a time.
In plain terms
ACH is the network behind most everyday US electronic payments — direct-deposit payroll, recurring bill payments, tax refunds, and vendor payouts. Instead of settling each payment individually, banks collect ACH instructions and process them together in scheduled batches, which is what keeps the cost per transaction very low.
There are two basic directions: an ACH credit pushes money from the sender to the recipient (for example, payroll landing in an employee’s account), and an ACH debit pulls money with authorization (for example, a subscription charge).
How it works
- The sender (the “originator”) submits a payment instruction with the recipient’s bank routing number and account number.
- Their bank batches the instruction with others and sends it to an ACH operator (the Federal Reserve’s FedACH or The Clearing House’s EPN).
- The operator sorts the entries and routes each one to the recipient’s bank.
- The recipient’s bank posts the funds; standard ACH settles in one to two business days, while Same Day ACH can settle the same business day.
Key characteristics
- Domestic and USD-based — ACH is a US network; cross-border equivalents use different rails.
- Batched, not instant — standard entries clear in 1–2 business days; Same Day ACH is available for eligible amounts.
- Low cost — typically a small flat fee, which makes ACH efficient for high-volume payouts.
- Reversible in limited cases — unlike wires, some ACH entries can be returned or corrected under Nacha rules.
Example
A company running weekly contractor payouts can send hundreds of ACH credits in a single batch. Each contractor is paid to their bank account using their routing and account numbers, and the funds typically arrive within one to two business days at a fraction of the cost of a wire.
How Payouts.com fits in
Payouts.com supports ACH as one of 40+ payout rails, so you can pay US recipients by ACH while reaching recipients elsewhere on local rails, cards, or wallets from the same platform. Routing logic picks an appropriate rail per destination, and every payment flows into automated reconciliation.
Frequently asked questions
How long does an ACH transfer take?
Standard ACH transfers settle in one to two business days. Same Day ACH can settle on the same business day for eligible transactions submitted before the network’s daily cut-off times.
What is the difference between ACH and a wire transfer?
ACH is batched, low-cost, and typically clears in one to two business days, while a wire transfer is processed individually, settles the same day, and is generally irrevocable but costs more. ACH suits high-volume, routine payments; wires suit urgent or high-value ones.
Can an ACH transfer be reversed?
In limited situations. Under Nacha rules certain ACH entries can be returned or reversed — for example, for a duplicate or erroneous amount — within defined time windows. This differs from wires, which are generally final once sent.
