Short answer
ACH vs credit card comes down to cost, speed, and risk. Card fees grow with the payment: Visa's interchange alone on a keyed commercial card is 2.70% + $0.10. ACH is priced by your bank, so a large invoice can cost a small fraction of that. ACH debits settle the same or next banking day, and ACH return windows are shorter than card dispute windows.
ACH vs credit card is really a question of which trade-offs you want on each payment. A credit card payment is approved in seconds, costs a percentage of the sale, and can be disputed months later. An ACH payment is a bank-to-bank transfer through the Automated Clearing House network: it costs whatever your bank or provider charges, usually settles within one banking day, and can come back unpaid within set return windows. For large B2B invoices from customers you know, that trade-off often favors ACH. For walk-in sales and new customers, cards usually win.
ACH is not a niche rail. Nacha, the organization that governs the network, counted 35.2 billion ACH payments worth $93 trillion in 2025, including close to 8.1 billion business-to-business payments.
ACH vs credit card at a glance
| Factor | ACH | Credit card |
|---|---|---|
| Cost | Set by your bank or ACH provider; get the per-payment and return fees in writing | Interchange plus network and processor fees, mostly a percentage of the sale |
| Speed | Debits settle the same or next banking day; Same Day ACH covers payments up to $1 million | Approved in seconds; when the money lands depends on your processor |
| At the moment of payment | No real-time approval; a debit can come back unpaid | Authorized before the customer leaves or the order ships |
| Reversal window | Most returns within 2 banking days; 60 days for unauthorized consumer debits | Disputes can arrive months later |
| Fee on the payer | Not applicable | A surcharge on credit cards, where state law allows |
| Best fit | Recurring and large B2B invoices from known customers | New customers, small or one-off sales, buyers who pay by card |
Which costs less: ACH or a credit card?
For large payments, ACH usually wins, because card costs scale with the amount of the sale. A card payment carries interchange, which goes to the bank that issued the card, plus network fees and your processor's markup. On Visa's April 18, 2026 interchange schedule, a corporate or purchasing card keyed in without enhanced data falls under Commercial Card Not Present at 2.70% + $0.10. A consumer Visa Signature card tapped in person is 1.65% + $0.10.
ACH pricing comes from your bank or ACH provider, not from a network schedule you can look up (Clearo's ACH payment processing is quoted per business too). Get three numbers in writing: the fee per payment, the fee per return, and any monthly charge. Then compare. Here's how the gap looks with a placeholder ACH fee of $1.00 per payment, which you should replace with your bank's real number:
| Invoice | Visa commercial card, keyed (interchange only) | ACH at a placeholder $1.00 |
|---|---|---|
| $500 | $13.60 | $1.00 |
| $5,000 | $135.10 | $1.00 |
| $50,000 | $1,350.10 | $1.00 |
The card column is interchange only; processor and network fees come on top. Card costs can drop a lot when the sale carries line-item data: at Visa's Commercial Product 3 rate of 1.75% + $0.10, the $50,000 invoice carries $875.10 in interchange instead. That's still real money, which is why we cover Level 3 credit card processing separately for suppliers who take big card payments.
Small payments are different. On a $40 sale tapped in person on a Visa Signature card, interchange is 76 cents, and a fixed ACH fee plus the hassle of collecting bank details can cost you as much.
How fast does each one settle?
ACH is faster than its reputation. According to Nacha, ACH debits settle the same day or the next banking day, credits can settle the same day, the next banking day, or in two banking days, and about 80% of all ACH payments settle in one banking day or less.
Same Day ACH speeds that up. Payments of up to $1 million can use it, with three settlement times each banking day (Nacha). Nacha's schedule shows, for example, a 10:30 a.m. ET submission deadline that settles at 1:00 p.m., and a 2:45 p.m. ET deadline that settles at 5:00 p.m. (Nacha schedule). The per-payment limit is set to rise to $10 million on September 17, 2027. Your bank sets its own cutoffs ahead of Nacha's deadlines, so ask what yours are.
A card payment is approved in seconds, but approval isn't the same as money in the bank. Funding depends on your processor's batch and deposit schedule. We offer same-day or next-day funding options, and our guide to same-day funding explains how that works.
Which is riskier: ACH returns or card chargebacks?
They fail in different ways. ACH has no real-time approval, so a debit can bounce, but the windows for sending it back are short. Cards are approved up front, but the dispute window stays open far longer.
On the ACH side, Nacha's rules set a standard two-day return timeframe, with extended returns reserved for specific cases (Nacha). Consumer accounts get an extended right of return of 60 days for unauthorized debits (Nacha). For business accounts, an unauthorized debit has to come back within 2 banking days (Nacha). That's a big reason ACH debits fit B2B billing: once the return window closes, the payment is far more settled than a card sale.
Nacha also tightened fraud expectations in 2026. A first phase of new risk management rules took effect on March 20, 2026, and the second phase, in June, applies regardless of origination volume (Nacha). It requires every non-consumer originator to have risk-based processes intended to identify ACH entries initiated due to fraud. If you start ACH debits to collect from customers, you're an originator, so ask your bank what it expects from you, and confirm any change to a payee's bank details by calling a number you already have on file.
On the card side, disputes can come late. Mastercard's chargeback guide, for example, allows some service disputes to be filed within 120 calendar days from when the services ceased, with an outer limit of 540 days (Mastercard). In exchange, you get an authorization at the moment of sale and tools such as address and security code checks.
Our take: for established business customers, ACH's short return window is a real advantage. For one-time buyers you don't know, a card authorization tells you more at the moment of sale.
ACH credit or ACH debit: which one fits B2B billing?
There are two ways to get paid by ACH. With an ACH credit, your customer pushes the payment from their bank to yours, the way many companies pay their vendors. With an ACH debit, you pull the payment from the customer's account after they authorize it, the way a utility collects a bill. Nacha says debits make up just over half of ACH payments and credits just under half.
- An ACH credit leaves the customer in control of timing. You publish your bank details on the invoice and wait for their payables run. Setup is light, but you can't speed them up.
- An ACH debit puts you in control of timing, which suits recurring billing. In exchange, you need the customer's authorization, and you carry the return risk described above.
Either way, protect your bank details. Put them only on invoices you send, and tell customers you will never change them by email alone.
When should you steer customers to ACH?
Push for ACH when the payment is large, repeats, or comes from a customer you already trust:
- Invoices above a dollar threshold you choose, such as $2,500, where card fees start to sting.
- Recurring B2B billing, such as monthly service contracts, collected by ACH debit with the customer's written authorization.
- Customers who pay by paper check today and would rather not.
- Big project payments from established clients.
Here's what that can be worth. Say you send 40 invoices a month averaging $3,000, and customers pay all of them with keyed commercial cards. At Visa's Commercial Card Not Present rate, each one carries $81.10 in interchange. Move a quarter of them, 10 invoices, to ACH at the same placeholder $1.00 fee, and you save $80.10 per invoice: $801 a month, or $9,612 a year, before processor markup. Swap in your own bank fee and card mix to get your real number.
You can steer without forcing anything. Put your bank details or ACH payment option first on the invoice, set ACH as the default for recurring billing, or offer a discount for paying by bank transfer. Visa's rules allow a merchant to offer a discount or incentive to pay with a method other than a Visa card, as long as prices are displayed the way Visa requires (Visa).
When is a credit card the better choice?
Cards make more sense when:
- The customer is new, and you want an authorization before you ship or start work.
- The ticket is small enough that the fee is a rounding error.
- The buyer's company pays its vendors with a corporate or purchasing card.
- The sale happens online or on site, where the card is right there.
- The buyer wants to pay later, and you'd rather the card issuer carry that credit than you.
For those payments, keep card acceptance easy: a payment link on the invoice from a virtual terminal gets you paid faster than waiting for a check.
Can you surcharge credit cards on large invoices?
In most states, yes, on credit cards only and within limits. Visa caps a surcharge at your merchant discount rate for that card or 3%, whichever is lower, requires notice to your acquirer at least 30 days ahead, and bars surcharges on debit and prepaid cards (Visa). That includes business debit cards, which are still debit cards. Mastercard lists a 4% maximum (Mastercard).
State law decides the rest. A supplier in Boston can't surcharge at all, because Massachusetts bans credit card surcharges, so steering large invoices to ACH is the main lever there. A firm in Denver can surcharge within the limits Colorado sets by statute; ask your processor how those limits apply to business-to-business invoices. Nacha's rules, by contrast, are national, so the ACH side works the same anywhere in the US.
Here's the math on a $10,000 invoice paid by credit card with a 2.5% surcharge, assuming your cost on that card is at least 2.5%: the customer pays $10,250, and the $250 offsets most of your fee. If the same customer pays with a business debit card, no surcharge applies, and you absorb the full fee. Our credit card surcharging program handles the compliance, disclosure, and setup, and our guide to free credit card processing covers the state rules in more detail.
Common mistakes with ACH and cards
Watch for these when you run both side by side:
- Adding a surcharge to a business debit card. It's a debit card, and the networks don't allow it.
- Forgetting return fees. Ask your bank what a returned ACH payment costs before you price your terms.
- Shipping to a brand-new customer the moment an ACH debit goes out, before the return window has closed.
- Accepting a vendor's or customer's "new bank details" by email without calling to confirm.
- Letting every large invoice default to a card because it's easier, without ever offering ACH.
