A card-present sale, an online checkout, a manually keyed card, an invoice paid by ACH, and a pay-by-bank transfer have different percentage fees, fixed fees, caps, settlement timing, failure handling, and dispute exposure. Compare the full cost of your actual payment mix rather than choosing a processor from a single advertised rate.
For a U.S. business, start by separating in-person, online, keyed or card-on-file, and bank-based payments. Then model every fee against real ticket sizes and volumes, add plan, hardware, reconciliation, return, and dispute costs, and confirm the provider’s current schedule before signing up. The examples below use U.S. prices observed October 13, 2026; provider pricing and eligibility can change.

Start with the way customers actually pay
Payment acceptance is a customer-experience decision as well as a pricing decision. List the channels you need before comparing providers:
Free tools Windows power users keep installed
One-click scans. No signup required.
- In-person cards: chip, contactless, and magnetic-stripe fallback at a physical checkout.
- Online cards: payment fields, hosted checkout, or an ecommerce integration.
- Invoices: a payment link or portal sent after delivery or service.
- Manually keyed or card-on-file payments: staff-entered card details, recurring charges, or telephone orders.
- ACH or pay-by-bank: an account-to-account payment initiated from a customer’s bank account.
Each channel can have a different rate from the same provider. A business with $15 service tickets may be hurt by a large fixed fee, while a consultant collecting $2,000 invoices may benefit from a capped bank-transfer fee. A subscription business must also price failed payments, retries, customer notifications, and reconciliation time.
#1 Best Overall
The Federal Reserve Banks’ 2024 Report on Payments describes the 2023 Small Business Credit Survey, fielded from September through November 2023. It received 6,131 responses from employer firms with one to 499 employees in all 50 states and the District of Columbia; payment-module findings cover the 4,920 respondents who answered at least one optional payments question. In that surveyed population, 38% said collecting the full payment at purchase or service time represented their largest revenue share, while 28% collected payment after delivery, such as by invoice. More than 80% accepted at least three forms of payment. These are survey results from employer firms, not a rule that every sole proprietor should accept every method.
The 2024 Business Payments Study from Federal Reserve Financial Services found that 52% of surveyed businesses encouraged credit-card use and 47% encouraged ACH. Those figures describe reported business behavior, not a cost ranking. One medium-sized service business told the study, “Transaction fees are lower than cards and other online payment systems, improving margins and reducing operational costs.” That is the respondent’s experience with its own method, not an independently verified average.
Understand what a card fee includes
The Federal Trade Commission describes the authorization path as merchant to acquirer or processor, through the payment-card network to the issuing bank, with the response returning through the chain. The amount deposited to the merchant is reduced by the merchant discount. That deduction includes interchange plus other processing fees, so interchange alone is not your total acceptance cost.
When you compare a card plan, identify the percentage and fixed amount that apply to the exact channel. Then ask whether the quoted rate includes gateway, software, terminal, monthly, chargeback, refund, or international charges. A rate that looks low for a card-present transaction may be expensive for manually keyed invoices.
Debit routing is not a universal cap on card costs
The Federal Reserve Board’s Regulation II establishes standards for debit-card interchange fees and routing. Issuers and networks generally may not restrict debit processing to fewer than two unaffiliated networks or prevent a merchant from directing a transaction over an enabled network. The overview has exemptions for certain small issuers, government-administered programs, and reloadable general-use prepaid cards.

Regulation II concerns covered debit routing and interchange standards. It does not cap every merchant fee, does not set credit-card pricing, and does not guarantee that a particular processor will pass through a lower cost. Check current federal and state rules before using surcharges or cash discounts; an older FTC retailer guide should not be treated as current legal advice.
Current U.S. pricing examples (checked October 13, 2026)
These examples show why a fair comparison must use the right channel and include plan costs. They are provider-published schedules, not a claim that one provider is universally cheapest.
| Payment type | Listed rate | Illustrative fee on a $10 payment |
|---|---|---|
| Square Free, in-person card | 2.6% + 15¢ | 41¢ |
| Square Plus, in-person card | 2.5% + 15¢ | 40¢ |
| Square Premium, in-person card | 2.4% + 15¢ | 39¢ |
| Square Free, online card | 3.3% + 30¢ | 63¢ |
| Square Plus or Premium, online card | 2.9% + 30¢ | 59¢ |
| Square manually entered or card-on-file | 3.5% + 15¢ | 50¢ |
Square lists a $0 monthly plan fee for Free. Plus and Premium have monthly per-location charges, so the lower transaction rate only saves money after the processing savings exceed that recurring fee. Square’s plan-specific pricing can change; verify the live schedule and eligibility.
| Square bank-transfer route | Listed pricing | What the cap changes |
|---|---|---|
| ACH by invoice on Plus or Premium | 1%; $1 minimum; $10 maximum | A 1% calculation above $10 is limited to $10 |
| ACH by API | 1%; $1 minimum; $5 maximum | A 1% calculation above $5 is limited to $5 |
PayPal’s U.S. fee page illustrates a different structure. Its Advanced Credit and Debit Card Payments option is described as interchange pass-through costs plus 0.49% and a fixed fee, subject to activation and agreement terms. The same page lists an additional 1.50% for certain international card transactions under its “all other” card-payment services, while its Interchange Plus Plus type has no additional percentage-based international fee. Confirm the exact fixed fee, payment type, eligibility, and contract before comparing it with a flat-rate plan.
Calculate the full cost for your business
Build a simple worksheet using one month of realistic data. For each payment route, record:
- Typical ticket and the range of ticket sizes.
- Number of transactions and total volume.
- Share of sales paid in person, online, by invoice, or by bank transfer.
- Percentage fee and fixed fee per transaction.
- Minimums, caps, international add-ons, and recurring software or location fees.
- Hardware purchase or rental, gateway, integration, and staff time for reconciliation.
- Refund, returned-payment, dispute, and chargeback costs.
- Settlement timing and any cash-flow cost from waiting for funds.
Use this formula for a percentage-plus-fixed card price:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minutetotal processing cost = (sales volume × percentage rate) + (transaction count × fixed fee) + recurring and incident fees
For a bank-transfer schedule, apply the minimum and cap to each transaction before adding the results. A 1% rate with a $1 minimum costs $1 on a $40 invoice, which is 2.5% of that invoice. On a $2,000 API payment, 1% would be $20, but a $5 cap limits the listed processing fee to $5. Whether that is advantageous depends on returns, setup, software, and customer uptake.
Why small tickets magnify fixed fees
At a $10 in-person sale, Square Free’s listed 2.6% plus 15¢ equals 41¢, or 4.1% of the sale. At a $100 sale, the same schedule produces $2.75, or 2.75%. The rate did not change; the fixed 15¢ became a smaller share. Online pricing has both a higher percentage and a 30¢ fixed amount in the cited schedule, so run the same calculation using your actual average and low-end tickets.
Include plan break-even math
If a paid plan reduces the in-person rate by 0.1 percentage point compared with Free, every $10,000 of monthly in-person volume saves $10 before the paid plan’s monthly charge. A 0.4-point reduction saves $40 per $10,000. Compare that saving with the plan’s per-location fee, hardware requirements, and any software features you would otherwise buy separately. Do not assume a higher tier wins merely because its transaction rate is lower.

When ACH or pay-by-bank can help
ACH is an electronic transfer between depository institutions over the Automated Clearing House network. It can suit invoices, tuition, professional services, memberships, and other situations where customers already expect to pay from a bank account. A provider may offer ACH through an invoice link or an API, with different minimums, caps, settlement timing, and return handling.
Pay-by-bank can use an account-to-account authorization rather than a card number. The Federal Reserve’s July 7, 2025 analysis warns against a blanket claim that point-of-sale pay-by-bank creates significant merchant savings. Total fees depend on transaction type, value, volume, provider pricing, upfront and ongoing operating expense, security and compliance costs, business type, and customer base. A lower quoted transaction fee does not prove a lower total cost.
The United States has two major instant-payment systems identified in that analysis: FedNow, operated by the Federal Reserve since July 2023, and RTP, operated by The Clearing House since 2017. They are payment rails, not automatically a consumer-facing checkout product. A merchant generally needs a bank or provider that offers practical acceptance, account verification, records, and support on the rail. Fast settlement is not synonymous with low cost.
Model bank-payment risks, not just savings
- Returns and failed debits: budget for customer-not-authorized claims, insufficient funds, notifications, and retry work.
- Customer adoption: some buyers prefer cards for rewards, credit, or familiar dispute processes.
- Reconciliation: match bank references to invoices and subscriptions; a manual process can erase a nominal fee saving.
- Security and compliance: include account-linking, authentication, access controls, and vendor oversight.
- Disputes and protections: do not claim that bank payments eliminate fraud, reversals, or consumer protections.
Choose the channel that matches the workflow
Retail, food, and appointments paid on site
Use a contactless and chip card reader when customers pay at a counter or in the field. The reader enables acceptance; it does not set the processor’s rate or lower that rate by itself. Compare the card-present schedule, device cost, receipt options, offline behavior, tipping, refunds, and settlement timing. If your tickets are small, pay particular attention to the fixed cents component.

Online transactions often carry a different percentage and fixed fee from in-person payments. Price the hosted checkout, payment-page security, recurring billing, and failed-payment recovery together. Confirm whether international cards, currency conversion, and manually entered orders are priced separately.

- Helpful in various ways
Professional services and invoice businesses
Offer an invoice method that makes the customer’s preferred route visible without forcing staff to re-key payments. Compare card, ACH, and any pay-by-bank option on the same invoice amounts. A capped ACH fee may be useful for high-value invoices, while a minimum can make it unattractive for small balances. Track days-to-payment and returned invoices, not only the nominal fee.
Recurring and card-on-file charges
Keyed or card-on-file transactions can have a higher rate than in-person payments. Include token or account-updater features, authorization records, retry rules, cancellation handling, and the time required to resolve expired cards. A slightly higher fee can be rational if it materially reduces unpaid renewals and staff follow-up.
Control operational and risk costs
Ask every provider how refunds are credited, whether the original processing fee is returned, and what a dispute costs. Confirm the evidence deadline and who responds to retrieval requests. Review fraud tools, authorization controls, address or identity checks, and any additional charge for them; no payment method removes fraud risk.
Measure settlement in business terms. A payment that arrives quickly may reduce borrowing or overdraft pressure, but an instant rail can bring subscription, integration, or monitoring expense. Conversely, a lower-fee ACH debit that settles later may be acceptable when your invoice terms already allow several days.
Reconcile daily or on a defined schedule. Match processor deposits to gross sales, fees, refunds, taxes, tips, and disputes. Separate channel totals in accounting so you can see whether a change actually lowered cost. Revisit the analysis after adding locations, changing average ticket, or introducing international sales.
A practical implementation checklist
- Export three months of sales. Group transactions by amount, channel, payment method, refunds, and recurring status.
- Define customer requirements. Note whether buyers expect contactless cards, invoice links, ACH, subscriptions, mobile acceptance, or international cards.
- Request complete schedules. Get percentage, fixed, minimum, cap, plan, hardware, international, refund, return, and dispute charges in writing.
- Run transaction-level math. Apply each schedule to low, typical, and high tickets; do not use only the monthly average.
- Add labor and integration. Estimate setup, reconciliation, failed-payment follow-up, support, and software work.
- Test the customer path. Check checkout completion, invoice reminders, receipts, refunds, and settlement reports with a small controlled launch.
- Monitor net cost. Review effective fee percentage, declines, returns, disputes, days to settlement, and customer conversion each month.
- Reprice when facts change. Recalculate after a plan change, new location, new ticket mix, or material growth in ACH or international volume.
How to decide without chasing a misleading headline rate
Choose the option with the lowest sustainable total cost that still lets customers pay in the way they prefer and gives your staff a reliable workflow. For a card-heavy storefront, that may mean optimizing the in-person rate and fixed fee. For an invoice-led service firm, a capped ACH route may deserve a pilot alongside cards. For online sales, conversion, fraud controls, and integration can outweigh a small difference in the listed percentage.
Do not rank Square, PayPal, or any other provider as universally cheapest from the schedules above. Their examples cover different products, channels, and eligibility terms. Recheck current U.S. fee pages, calculate your own mix, and treat any bank-payment savings as a hypothesis to validate after operating costs, customer acceptance, and risk are included.
