How to Make an ACH Payment: Timing, Limits, and Fixes

To make an ACH payment, log into your bank’s online portal or a payment app, add the recipient as an external account using their routing number, account number, account type, and legal name, verify the account, then enter the amount and submit. Funds usually settle within one to three business days, or within hours if you choose Same-Day ACH.

What You Need Before You Start

Four pieces of information about the recipient’s account make an ACH payment possible:

  • The nine-digit routing number that identifies their bank. It sits on the bottom left of a paper check or in the account details screen of any online banking portal.1American Bankers Association. ABA Routing Number
  • The account number for the specific account.
  • The account type (checking or savings). Getting this wrong can cause the receiving bank to reject the payment.
  • The legal name of the person or business that owns the account.

Check every digit of the account number before you submit. Under the Uniform Commercial Code, a receiving bank that doesn’t know about a mismatch between the recipient’s name and the account number may rely on the account number alone.2Legal Information Institute.

Sending the Payment Through Your Bank

Most banks and credit unions let you initiate ACH payments from their website or mobile app. Labels differ, but the path is the same everywhere.

Sign in and find the section called “Transfers,” “Send Money,” or “Bill Pay.” Choose the option to add an external account or new payee. Enter the routing number, account number, and account type. Many banks let you nickname the link (something like “Landlord” or “Mom’s Savings”) so you can reuse it later.

Before releasing a full payment to a new external account, your bank will verify the link. Two methods are common. With micro-deposits, your bank sends two tiny transfers of a few cents each to the external account; you then confirm the exact amounts to prove you have access. This takes one to two business days. Instant verification lets you log into the external bank through a secure third-party connection and confirm the account in seconds. Not every bank supports instant verification, so micro-deposits remain the fallback.

Once the account is linked, enter the amount, choose a transfer date, and review the confirmation screen. Submitting creates an electronic instruction that your bank hands off to the ACH network.

Save the confirmation number the bank gives you. If something goes wrong, that number is how the payment gets traced through the system. When the transfer clears, it will show up on your bank statement as a completed debit with a short description or merchant ID next to the amount.

Sending Through a Third-Party App

You don’t have to go through your bank directly. Venmo, Zelle, PayPal, and business-focused tools like Bill.com all move money across the ACH network behind the scenes. Setup looks similar: link your bank account to the platform through instant verification or micro-deposits, then send payments through the app. Zelle shortcuts the process by letting you send to an email address or phone number, since both ends are already connected to banks through the Zelle network.

Fees depend on the service and the speed you pick. Venmo charges nothing for standard bank-funded transfers between users or for a standard withdrawal to your linked bank. Choose instant transfer and Venmo charges 1.75% of the amount, with a minimum of $0.25 and a cap of $25.3Venmo. About Venmo Fees For businesses, a 2022 industry survey put the median cost of sending or receiving an ACH payment at $0.26 to $0.50, compared with $2 to $4 for a paper check.4Nacha.

How Long It Takes

Standard ACH payments settle within one to three business days, depending on when you submit and the processing schedules of both banks.5Nacha. The ABCs of ACH Payments submitted late in the day or right before a weekend land on the slower end.

Same-Day ACH is the faster option. The network runs several processing windows throughout the business day, with morning and afternoon submission cutoffs in Eastern Time. Anything submitted before a cutoff settles the same day.6Nacha. Same Day ACH – Moving Payments Faster Phase 1 The per-transaction limit is $1 million.7Federal Reserve Financial Services. Same Day ACH Resource Center Anything larger drops back to standard next-day processing.

The ACH network does not process on weekends or Federal Reserve holidays. In 2026, there are eleven such holidays, including New Year’s Day (January 1), Memorial Day (May 25), Independence Day (July 4), Labor Day (September 7), Thanksgiving (November 26), and Christmas (December 25).8Federal Reserve Financial Services. Federal Reserve System Holiday Schedule A Friday-afternoon transfer won’t begin processing until Monday, and a holiday weekend stretches the gap further. Plan around that for rent, payroll, or anything with a hard deadline.

Limits to Expect

Beyond the $1 million Same-Day ACH cap set by network rules, individual banks impose their own daily and monthly limits on consumer ACH transfers. These typically range from a few thousand dollars up to around $25,000 per day, depending on your bank, account type, and relationship. If you need to move more, call your bank. Many will raise limits temporarily for verified customers.

If Something Goes Wrong

ACH payments fail for a short list of common reasons. The receiving bank sends back a standardized return code:

  • R01 — Insufficient funds. The receiving bank must return the transaction within two banking days.
  • R02 — Account closed.
  • R03 — No account found at the number you provided.
  • R04 — Invalid account number format.

Returned funds usually reverse within a few business days. Your bank may charge a returned-item fee, especially for R01 returns. For a payment that must arrive on time (a tax payment, closing funds, or payroll), confirm the recipient’s details ahead of time and keep enough in your account to cover the transfer plus any fees.

Reversing a Payment You Sent

The window is tight. Under NACHA rules, an originator can request a reversal within five banking days of the original settlement date, and only for specific reasons: a duplicate payment, the wrong recipient, or the wrong dollar amount.9Nacha. ACH Network Rules – Reversals and Enforcement A reversal is not guaranteed. The receiving bank can refuse it if the recipient’s account lacks the funds or has been closed. If the reversal fails, your next step is contacting the recipient directly.

Stopping a Recurring Debit From Your Account

If a company pulls money from your account on a schedule and you want to stop a specific payment, federal law is on your side. Under Regulation E, you can order your bank to block a preauthorized debit by notifying them at least three business days before the scheduled date. The notice can be oral or written. If you call it in, the bank may require written confirmation within 14 days, and the oral order expires if you don’t follow up.10Consumer Financial Protection Bureau. Section 1005.10 Preauthorized Transfers

Banks typically charge $15 to $36 to process a stop-payment order, though some waive or reduce the fee for online requests or premium accounts. Also contact the company directly to revoke your authorization. Stopping it only at the bank can prompt the company to resubmit the debit or flag your account as delinquent.

Unauthorized Debits

If someone pulls money from your account without permission, federal law limits what you owe, but only if you move fast. Under the Electronic Fund Transfer Act and Regulation E:

For a fraudulent debit that doesn’t involve a lost or stolen access device, such as someone submitting an unauthorized ACH debit using only your account number, you have no liability as long as you report it within 60 days of the statement that shows it.11Consumer Financial Protection Bureau. Section 1005.6 Liability of Consumer for Unauthorized Transfers Review your statements every month. The 60-day clock runs whether you look or not.
