eCheck vs ACH vs Wire Transfer vs Credit Card

ACH (Automated Clearing House) is the U.S. network banks use to move money between accounts in batches. It carries payroll direct deposits, bill payments, tax refunds and business invoices. Its rules are written by Nacha, the organization that governs the network.

Every ACH payment moves in one of two directions:

• ACH debit (a "pull"). You, the business, start the payment and take money from the customer's account after they authorize it. That's an eCheck. The customer gives you their routing and account numbers online, by phone or on a signed form, and your gateway sends the debit.
• ACH credit (a "push"). The customer starts the payment from their own bank and sends money into your account. Payroll direct deposit works this way, and so does a business paying your invoice through its bank's bill pay. You hand out your account details; you don't need a gateway to receive it.

So when someone asks "eCheck or ACH?", the useful question is "who starts the payment?" That changes what you control:

ACH credits are convenient for B2B invoices, but you wait on the customer. eCheck puts the timing in your hands, which is why rent, memberships, tuition and payment plans run on it. For how the money moves step by step, see what an eCheck is and how it works. If you're the one being asked to pay by eCheck, our guide to how to send an eCheck walks through it.

A wire transfer moves money one payment at a time between banks. In the U.S., most domestic wires between banks run on the Federal Reserve's Fedwire Funds Service. ACH works in batches. That one difference drives most of the rest.

• Speed. The Federal Reserve says Fedwire transfers are "immediate, final, and irrevocable once processed." Its business day runs from 9:00 p.m. ET the evening before to 7:00 p.m. ET, Monday through Friday, excluding holidays. Your bank sets its own, earlier cutoff. Standard ACH is slower but not slow: Nacha estimated in August 2023 that about 80% of ACH volume "settles in one banking day—or less." That's bank-to-bank settlement, though. When a provider pays out eChecks to a business, funding usually takes longer (see below).
• Same Day ACH. ACH can also settle the same day. Since March 18, 2022, Nacha has allowed Same Day ACH payments of up to $1 million each. In April 2026 Nacha's members approved raising that to $10 million, effective September 17, 2027 (approved, not yet in effect). Whether you can use Same Day ACH depends on your bank or provider.
• Cost. Banks charge a fee for each wire, and each bank sets its own, often for both sending and receiving. ACH costs far less per payment. Check your bank's fee schedule for its wire prices.
• Reversibility. A processed wire is final. You can't pull it back the way an ACH debit can be returned. That protects the person receiving it, and it's exactly why scammers ask for wires.
• Fraud. Because a wire can't be undone, fake "updated bank details" emails are a common trap. Confirm any new wire instructions by phone, using a number you already have, before you send or ask a customer to send.

When to use each:

• Wire: large, one-time, time-critical payments where final funds matter, such as a deposit on custom equipment or a property closing.
• ACH: anything regular or routine, such as invoices, rent, memberships, payroll and vendor bills, where a day or two doesn't matter and the lower cost does.

This is the comparison that matters most when you decide what to offer customers. ACH vs credit card comes down to four trade-offs.

1. Cost

Card fees are a percentage of each sale plus a small fixed fee, so they grow with the ticket. eCheck fees are much lower. Using Authorize.Net's published direct prices, checked October 13, 2026:

• eCheck: 0.75% of each eCheck.Net charge, with a $10 monthly minimum. On a $2,000 invoice, that's $15.
• Card: Authorize.Net's All-in-One plan is 2.9% + 30¢ per transaction. On the same $2,000, that's $58.30.

These are Authorize.Net's direct prices, not START's. Through a provider, prices, limits and funding times vary; ask for them in writing. Card pricing on a merchant account is often interchange-plus, the card network's cost plus a fixed markup. See interchange-plus pricing for how that works, and our eCheck and ACH processing fees guide for every eCheck fee type and a cost calculator.

2. Speed

A card is approved or declined in seconds. An eCheck isn't. Authorize.Net's developer guide says eCheck payments "do not receive immediate authorization from the customer bank." On funding, Authorize.Net gives two answers: its eCheck page says processing "typically takes three to five business days," while its developer guide says merchants "might wait up to seven days." Plan around the longer number. Our guide to how long an eCheck takes to clear has the details and a funding date estimator.

3. Disputes and returns

Both can come back after you've been paid, but the rules differ:

• eCheck: the customer's bank can return the payment for insufficient funds, a closed account or wrong numbers, usually within days. If a consumer says they never authorized the debit, Nacha's rules give their bank up to 60 days to return it. There's no card-style process for you to submit evidence inside the ACH network and win the money back. If you hold a valid authorization, you generally have to collect from the customer directly. See ACH return codes and returned eChecks.
• Credit card: under federal law (Regulation Z), a cardholder has 60 days after the first statement showing a billing error to dispute it with the card issuer. Card networks also set their own chargeback time limits, which vary by network and dispute reason. Unlike ACH, you can usually respond with evidence.

4. Refunds and customer preference

A card refund goes back to the card. An eCheck refund depends on its type, called an SEC code (Standard Entry Class code). On Authorize.Net, refunds through the gateway work for PPD (prearranged consumer) and CCD (business) eChecks, but not for WEB (online) or TEL (phone) eChecks, so you'd return that money another way. See ACH SEC codes.

Customers who want rewards points, or who pay small amounts on the spot, will usually reach for a card. Customers paying rent, a large invoice or a monthly bill are often willing to pay from their bank, especially if you tell them it keeps your prices down.

Both draw on the customer's checking account, and both can bounce. The difference is the paperwork:

• No mail, no deposit run. An eCheck is entered online, by phone or from a signed form. A paper check has to arrive and be deposited.
• Recurring without new checks. With the right authorization, you can charge an eCheck on a schedule. A paper check means a new check every time.
• Authorization looks different. The signature on a paper check is the permission. An eCheck needs consent captured online, on a recorded call or in writing, and you keep the record.

Rules and published prices as of October 13, 2026. Your own costs and timing depend on your bank and provider.

For most businesses that bill more than small, one-off amounts, the answer is cards and eCheck, not one or the other:

• Cards for customers who want speed, rewards or the convenience of a card, and for orders you ship right away.
• eCheck for large invoices and recurring bills, where a percentage card fee hurts and waiting a few days to fund doesn't.
• Wire instructions on request, for the occasional very large payment. Protect them, and confirm any change by phone.

eCheck is a poor fit when you ship high-value goods the moment an order comes in, when customers expect instant confirmation, or when many buyers bank outside the U.S. Authorize.Net's pricing page says its eCheck is "only available for businesses based in the U.S."

START sets up the merchant account and the Authorize.Net gateway together, and we've set up more than 60,000 Authorize.Net accounts over 20+ years. With Authorize.Net's eCheck service, eCheck.Net, cards and eCheck run through the same gateway: on your website, in the virtual terminal and on invoices. That means one merchant account and one gateway for both through START. Already on Authorize.Net? See Authorize.Net eCheck.Net for what's specific to that service.
