Key takeaways

• On a $50 tapped sale, Square's free plan charges $1.45. Across the four Visa card types compared here, interchange on that sale runs from about $0.25 on a regulated debit card to $1.15 on a Signature Preferred card.
• Your card mix and the markup decide whether a merchant account saves you anything on each sale. Your volume only decides how fast those savings cover the fixed monthly fees.
• In the illustrative model, break-even is about $5,100 a month with a debit-heavy mix and about $11,800 with a mix heavy in premium cards.
• On October 26, 2026, an appeals court upheld the ruling that vacated Regulation II's debit cap and sent it back to the Fed. On interchange-plus, the rewrite passes straight through to you. On a flat rate, it won't unless your payfac changes its pricing.

A payment facilitator usually costs less while your business is small. A dedicated merchant account usually costs less once your volume clears a break-even point, and that point depends mostly on your card mix and the markup you're quoted. In the payment facilitator vs. merchant account choice, you're weighing a flat rate that never changes against an interchange-plus bill that follows what each card actually costs, plus a fixed monthly fee that matters less as you grow. In the worked example below, an in-store shop with a $50 average ticket breaks even at about $5,100 a month. Shift its card mix toward premium rewards cards and that number more than doubles.

Payment Facilitator vs. Merchant Account: Whose Name Is on the Account

In a 2023 letter to the SEC, Visa defined a payment facilitator as a financial technology company that provides payment acceptance to merchants on behalf of an acquirer. The acquirer is the bank that sponsors merchants into the card networks. Square and Stripe are the best-known payment facilitators, or payfacs. The payfac holds the bank relationship, signs you up as a sub-merchant (Visa's term is "sponsored merchant") and receives settlement on your behalf. Signup is fast because most of the risk review happens after you start processing.

A dedicated merchant account is opened for your business specifically, through a sponsor bank and a processor or an Independent Sales Organization (ISO) such as MannyPay. You are underwritten before approval, and the account carries an approved monthly volume and average ticket. Pricing is usually interchange-plus. The card-issuing bank's interchange fee and the network's fees pass through at cost, and the provider adds a disclosed markup. Our comparison of merchant accounts and payment aggregators covers the structural differences in depth.

What One $50 Sale Costs Under Each Model

Square's published U.S. pricing on its free plan is 2.6% + 15¢ in person, 3.3% + 30¢ online and 3.5% + 15¢ for keyed-in or card-on-file payments. Its paid plans lower the in-person rate to 2.5% or 2.4% (plus 15¢) for a monthly subscription. Stripe's standard U.S. rate is 2.9% + 30¢ per successful card payment. In late 2025, Square raised its in-person fixed fee from 10¢ to 15¢ and its free-plan online rate from 2.9% to 3.3%, so older comparison pages understate the flat rate.

On a $50 tapped sale, Square's free plan charges $1.45 whatever card the customer uses. Under interchange-plus, the wholesale cost depends on the card. Here are four common Visa card types:

The debit rates come from Visa's U.S. interchange reimbursement fee table effective October 24, 2026. The credit rates come from Helcim's summary of Visa's U.S. rates. These four don't cover every card type. Visa's Traditional Rewards card costs more than the plain Traditional card at 1.65% + $0.10 (about 93¢ on $50). Keyed sales, Infinite cards and commercial cards can cost more than anything in this table. Network assessment fees and the provider's markup come on top, and the worked example below includes both.

When you read a quote, keep three layers apart. The regulated debit cap comes from federal regulation. Since October 1, 2011, the Federal Reserve's Regulation II, which implements the Durbin Amendment, has capped debit interchange for issuers with $10 billion or more in assets. The cap is 21¢ plus 0.05% of the sale, with 1¢ more for issuers that meet the Fed's fraud-prevention standards.

Visa's current table still applies that cap, but the courts have ordered the Fed to rewrite it (see the next section). The exempt debit and credit rates are Visa network pricing. Square's 2.6% is one processor's price. A flat rate charges a debit-heavy merchant credit-card prices on its cheapest cards, and that's where the gap between the two models is widest.

The Debit Cap Is Being Rewritten

In August 2025, a federal court in North Dakota ruled in Corner Post v. Board of Governors of the Federal Reserve System that the Fed had overstepped the statute. The court vacated Regulation II. It also put its own ruling on hold while any appeal ran, so debit interchange wouldn't become an unregulated market. On October 26, 2026, the Eighth Circuit Court of Appeals upheld that decision, which vacates the regulation and sends it back to the Fed to rewrite.

Early reporting on the appeals ruling gives no deadline for the Fed and no effective date for a replacement. Visa's October 2026 table still lists regulated debit at 0.05% + $0.21, so treat today's debit pricing as unchanged until the Fed acts or a higher court steps in. Credit union groups warn the new cap could be far lower, and some commentators argue a rewrite could leave room for a higher one. On a flat rate, nothing changes unless your payfac reprices. On interchange-plus, whatever the Fed decides passes straight through to you. This is general information, not legal advice, so confirm the current status with your processor or counsel.

Worked Example: Finding the Break-Even Volume

The model below uses Square's and Visa's published rates. The figures a merchant account provider would quote are illustrative:

• Sales: all tapped or dipped in person, $50 average ticket, all priced at the Visa rates above (Mastercard, American Express and Discover price differently).
• Card mix: 30% regulated debit, 10% exempt debit, 30% Traditional credit, 30% Signature Preferred.
• Network fees (illustrative): 0.15% of volume. Your statement shows the real figure.
• Markup (illustrative, not a MannyPay quote): 0.30% + $0.10 per sale.
• Fixed monthly fees (illustrative): $40 for statement, PCI, gateway and similar fees combined.

Weighted interchange on the average sale comes to $0.73. Add $0.075 in network fees and $0.25 in markup, and the merchant account costs $1.055 per sale against Square's $1.45. That saves 39.5¢ per sale, so the $40 in fixed fees is covered after about 102 sales, or roughly $5,100 a month.

Now change only the card mix, to 10% regulated debit, 5% exempt debit, 25% Traditional credit and 60% Signature Preferred. Weighted interchange rises to about $0.96 and the per-sale saving shrinks to about 17¢. Break-even climbs to roughly $11,800 a month. If nearly every customer taps a Signature Preferred card, this quote never wins: $1.15 + $0.075 + $0.25 comes to $1.475 per sale, more than Square's $1.45. Swapping Traditional cards for Traditional Rewards cards pushes in the same direction, only less sharply.

That corrects a common assumption. Volume alone doesn't make a merchant account cheaper. Card mix and markup decide whether you save anything per sale; volume decides how quickly that saving covers the fixed fees. Ticket size matters too. At a $20 average ticket with the original mix, the saving drops to about 10¢ a sale and break-even moves to roughly $7,700 a month. For more on the two structures, read interchange-plus vs. flat-rate pricing.

When a Flat Rate Is the Better Deal

A payfac often makes sense below your break-even volume, when sales come in irregularly, or when you need to take cards this week and can't wait for underwriting. It can also win if your customers lean on premium rewards cards, as the second mix shows. Before you leave, ask your payfac whether it offers custom pricing at your volume.

Compare online sales with online rates. Card-not-present interchange runs higher than card-present. Helcim's summary of Visa's table lists a keyed Signature Preferred sale at 2.52% + $0.10, against 2.10% + $0.10 tapped, and payfacs charge more online too. If you measure an e-commerce store's 3.3% + 30¢ against interchange for tapped cards, a merchant account will look better than it is.

Your industry shifts the math. Restaurants and bars run small tickets and adjust tips after authorization, so check the per-sale fee as closely as the percentage. Retailers concentrate volume in holiday and back-to-school peaks. Those peaks can justify a merchant account on annual volume, and the same spikes are what trigger payfac reviews. Salons and spas mix walk-in tickets with prepaid packages and memberships, which brings recurring billing and stored cards into the comparison.

Holds, Underwriting and Visa's $1 Million Line

Payfacs approve quickly, so they rely on monitoring after signup to catch the risks that underwriting would catch up front. When something looks off, automated systems can pause payouts or close the account. Common triggers include a sudden jump in volume, an unusually large ticket, rising refunds or chargebacks, and sales that don't match the business described at signup. Our explainer on what "instant approval" really means covers why fast approval and later reviews go together.

A merchant account sets those expectations before you process. It isn't immune to holds or reserves, and running far beyond your approved profile can still prompt a review. The difference is that you can ask for a limit increase ahead of a spike you know is coming. Businesses in categories that payfacs restrict may need high-risk merchant account processing from the start.

Visa's rules also mark the point where the payfac model starts to strain. In the U.S. and Canada, once a sponsored merchant's annual Visa volume reaches $1 million (raised from $100,000), the acquiring bank must sign a direct agreement with that merchant. The merchant has two years to complete it. The payfac can keep settling on your behalf, so you aren't forced off the platform. If you're near that line, though, you're well past the break-even volumes in the example above.

Switching Without a Gap in Deposits

1. Pull three months of statements and note your volume, number of sales, average ticket, in-person versus online split and debit share. Ask for quotes built on that mix with every monthly, annual, PCI and gateway fee listed, then compare the merchant processing quotes side by side.
2. Read the agreement for term length, equipment terms and any early termination fee. Our guide to avoiding merchant account early termination fees lists the clauses to look for.
3. Get approved and test the new account before you cancel anything. Do it in a quiet month, not your peak season.
4. Order hardware early, since payfac devices are usually locked to their platform. Options include smart terminals from Clover, Valor, Dejavoo and PAX. Online stores reconnect checkout through a supported payment gateway. Test sales, refunds and voids.
5. Ask whether your stored card data can be exported to your new PCI-compliant processor. If it can't, plan how subscription customers will re-enter their cards.
6. Keep the old account open until final payouts, refunds and chargebacks settle. A mid-year switch can mean more than one Form 1099-K, so reconcile your 1099-K forms before tax time and check tax questions with a qualified professional.

A dedicated account also gives you access to MannyPay's cost programs: cash discount, dual pricing and surcharging where permitted. Some eligible merchants use them to offset part or all of their processing costs. Each program has card network rules, and surcharging also has state rules, so review the requirements before enrolling.

Start with last month's statement. Count your sales, find your debit share and run this:

Monthly savings = Number of sales × (payfac fee per sale − interchange-plus cost per sale) − fixed monthly fees

If the per-sale difference is positive and your number of sales covers the fixed fees with room to spare, get real quotes. MannyPay will price your actual card mix when you request a free processing quote, and a specialist responds within one business day.

I fixed all four flagged problems:

• Rewards label: I checked the rate against Helcim's summary of Visa's table. 1.51% + $0.10 is the rate for the plain Traditional card, and Traditional Rewards is 1.65% + $0.10. I relabeled the row "Traditional credit (CPS/Retail)" and used the same label in both card mixes. Because the rate itself was right, the weighted interchange, the break-even figures ($5,100, $11,800 and $7,700) and the volume table don't change. I rechecked all of them. I also added a sentence giving the Traditional Rewards rate so readers can see the difference.
• Flat-rate takeaway: It now says a flat-rate merchant won't see the change "unless your payfac changes its pricing."
• Debit cap status: The status is now explained in one place. The North Dakota court vacated Regulation II in August 2025 but put its own ruling on hold during the appeal. The Eighth Circuit upheld it on October 26, 2026, which vacates the rule and sends it back to the Fed. Early coverage gives no deadline and no effective date for a replacement, and Visa's current table still applies the cap. "Vacated" matches the sources.
• Interchange range: The takeaway now says it covers "the four Visa card types compared here." The body also says that keyed, Infinite and commercial cards can cost more, and gives the keyed Signature Preferred rate (2.52% + $0.10) as an example.

I also cut a few three-item lists in the body. I ran out of web searches before I could recheck the Square and Stripe rates, Visa's $1 million rule and Visa's SEC definition. Those come unchanged from the previous version and its listed sources, so it's worth one more check before publishing.
