ACH and wire transfers both move money between US bank accounts, but they work differently. A wire through the Federal Reserve's Fedwire Funds Service settles the same day and is final once credited, so it suits large one-off payments. ACH moves payments in batches that settle the same day or one to two business days later. An ACH debit can be pulled with the payer's authorization, so it suits recurring payments. It can also come back: a consumer can dispute an ACH debit for up to 60 days.
What is a wire transfer?
The Federal Reserve runs a wire service called the Fedwire Funds Service. The Fed describes it as the service banks, businesses and government agencies rely on for mission-critical, same-day transactions. Payments are credited to banks' Federal Reserve master accounts, and participants benefit from the finality of those payments. The Fed lists settling commercial payments among its uses.
What is an ACH payment?
ACH payments move on the ACH Network, which reaches all US bank and credit union accounts under rules written by Nacha. Payments travel in files that the Federal Reserve and The Clearing House sort and pass between banks. They can settle the same business day, or one or two business days later. An ACH payment can be a credit, pushed by the payer, or a debit, pulled by the payee with the payer's authorization. See ACH payment.
How do ACH and wires compare?
| ACH | Wire (Fedwire) | |
|---|---|---|
| Speed | Same day, or one to two business days | Same day |
| Can it come back? | Yes. Debits can be returned or disputed | Final once credited |
| Cost | Set by the processor or bank. On Stripe, 0.8% capped at $5 | Set by each bank |
Which one costs less?
Each bank sets its own wire fees, so there's no single figure to quote. ACH pricing also depends on who processes it. Stripe's standard US price for ACH Direct Debit is 0.8% per payment, capped at $5. So no single ACH payment through Stripe costs more than $5.
Can a payment be reversed?
A Fedwire payment is final once it's credited. ACH is different. Per Stripe's documentation, a customer can dispute an ACH debit through their bank for up to 60 calendar days on a personal account, or two business days on a business account. Disputes inside those windows are final. A debit can also be returned for reasons like insufficient funds or a closed account. See ACH returns on payment plans.
Which suits a payment plan?
ACH, in most cases. A plan collects many payments on a schedule. An ACH debit can be pulled from the customer's account under one standing authorization, so the customer doesn't have to send each payment. Stripe describes ACH Direct Debit as popular for businesses with large or recurring transactions. A wire suits a one-off payment where the payee wants same-day, final funds.
The trade-off is risk. A wire won't bounce once credited. An ACH debit can, so treat each one as pending until it confirms.
