What Is Pay by Bank? A Lower-Cost Way to Take Payments
Pay by Bank Lets a Customer Pay Straight From Their Checking Account
Almost every payment a small business takes runs over a card network. Even the ones that do not feel like cards — a tap, a digital wallet, a saved card on file — are still card transactions underneath, carrying card-network interchange and the fees stacked on top of it. Pay by bank is the option that steps off that track. Instead of charging a card, the customer authorizes a payment that moves directly from their bank account to yours.
You may also see it called bank payment, account-to-account payment, or open banking payment. The branding varies; the idea is the same. The money travels over the banking system’s own rails rather than Visa’s or Mastercard’s, which changes both what it costs and how it behaves. For some businesses that is a meaningful saving. For others it solves nothing and adds friction. Knowing which one you are is the whole exercise.
Here is what pay by bank actually is, the rail it runs on, where it earns its place, and where a card is still the better tool.
The Money Moves Bank to Bank, Not Card to Card
When a customer pays by bank, they approve a transfer from their checking account to the business’s account. In the United States that transfer almost always settles over the ACH network — the same system behind direct deposit and recurring bill payments — or, increasingly, over a faster real-time rail. There is no card number, no card network, and therefore no interchange fee of the kind that drives most of a card transaction’s cost.
The newer wrinkle is how the customer authorizes it. Older bank-payment flows meant typing in a routing and account number by hand, which was clumsy and error-prone. Modern pay-by-bank flows let the customer log in through their own bank to approve the payment, so the account details are confirmed by the bank rather than keyed in. That is the piece usually labeled open banking, and it is what has made bank payment smooth enough to put in front of a retail customer at all.
If you already accept ACH payments for invoices or recurring billing, pay by bank is not a new world — it is a more polished, customer-facing version of the same bank-to-bank transfer you already understand.
No Interchange Means a Flatter, Lower Fee
The reason anyone bothers with pay by bank is cost. A card transaction’s biggest single component is interchange — the fee the card networks set and the customer’s issuing bank collects — and it scales with the size of the sale. A bank payment skips that entirely. ACH transfers are typically priced as a small flat fee per transaction, or a low percentage with a cap, rather than the roughly two to three-plus percent a card sale carries.
On a small purchase the gap may not matter. On a large one it is dramatic: the percentage-based card fee climbs with the ticket size while a flat bank-payment fee stays put. A business taking a few high-value payments a month can save more from moving those off cards than from any amount of rate negotiation on the card side. That is why bank payment shows up first in places where the tickets are big and predictable.
A flat per-transaction fee on a $4,000 invoice is a rounding error next to card interchange on the same amount. The larger and less frequent your payments, the more a bank-payment option is worth setting up.
High-Ticket, Recurring, and B2B Payments Gain the Most
Pay by bank shines wherever the payment is large, repeated, or both. Recurring billing — memberships, tuition, subscriptions, retainers — is a natural home, because the customer authorizes once and the low flat cost repeats every cycle. So are high-value one-off payments: a contractor’s progress draw, a wholesale order, a professional-services invoice, a deposit on a big-ticket purchase.
It is especially strong for business-to-business payments, where the move off cards is already well underway. Business buyers paying other businesses have been shifting to bank transfers at scale, because the per-transaction economics on a four or five-figure invoice are simply better than a card. If you invoice other businesses, offering a bank-payment option on that invoice is often the single highest-leverage change you can make to your processing costs.
Sending the invoice through your accounting software and collecting the payment by bank rather than card keeps your books clean and your cost per payment low — without changing the customer’s experience much beyond which button they click.
It Is Not a Drop-In Replacement for Card Acceptance
Bank payment is a specialist tool, and pretending otherwise leads to disappointment. The first limit is speed. A standard ACH transfer is not instant — funds can take a day or more to settle, where a card authorization is immediate. For a counter sale where the customer walks out with the goods, that delay matters; for an invoice paid over a few days, it does not. Faster real-time rails are closing this gap, but availability still varies by bank.
The second limit is consumer habit and rewards. Many customers like paying by card, partly out of habit and partly because they earn points or cash back doing it. Asked to pay straight from their checking account instead, some will simply prefer not to — so bank payment usually works best as an option alongside cards, not as a forced replacement. Push it too hard at the register and you lose sales rather than fees.
Before you steer customers toward bank payment, make sure your cash-flow timing can absorb a settlement that is not instant. For recurring and invoiced payments this is rarely a problem; for same-day point-of-sale, it can be.
Three Things to Confirm First
If pay by bank looks like a fit, a short checklist keeps the rollout clean. None of these is difficult, but skipping them is how a good idea turns into a support headache.
Start with your processor. Bank payment runs through your merchant services setup the same way card acceptance does, so confirm your provider actually offers it and on what terms — the per-transaction fee, any percentage cap, and how settlement timing is handled. Next, look at where it lives in your checkout or invoicing flow; the option needs to be visible and easy, or customers default back to the card without thinking. Finally, decide how you will handle a failed or returned payment. A bank transfer can bounce for insufficient funds days after it looked complete, so you need a clear process for re-collecting, the same way you would for a returned check.
You are not signing up with a separate payment company on the side. Bank payment is an acceptance method layered onto your existing merchant account, so your funding, statements, and reporting work the way they already do.
Frequently Asked Questions
Essentially yes, in the US. Pay by bank is a customer-facing bank-to-bank payment that usually settles over the ACH network. The difference is the authorization: modern flows let the customer approve through their own bank rather than keying in account numbers, which is the part often called open banking.
Because it skips interchange. A card sale carries a percentage-based network fee that grows with the ticket; a bank payment is typically a small flat fee instead. The larger the payment, the bigger the gap — which is why bank payment is most worthwhile on high-value and recurring transactions.
Rarely. It works best as an option alongside cards, not a replacement. Many customers prefer cards for habit and rewards, and bank settlement is not instant. Offer it where the economics matter — large, recurring, or B2B payments — and keep cards available for everyone else.
Send Us Your Ticket Sizes. We’ll Tell You If Pay by Bank Pays Off.
Bank payment is not right for every business, but for some it quietly removes the single biggest line on the statement. Tell Brookside what you charge and how often — especially if you take large or recurring payments — and we’ll tell you honestly whether moving some of them off cards would save you money, where it would slow you down, and whether your current processor even supports it.
