Credit card surcharge on B2B accounts: who should pay the fee?
November 8, 2026
A credit card surcharge is the third-best answer on B2B accounts. Five ways to pay a $10,000 invoice compared, with Visa, Mastercard and state rules dated.
Executive summary
The customer should pay the card fee on a B2B account only after cheaper fixes fail. Steer large invoices to bank payment first, then discount or price the cost in. A surcharge comes third: Visa caps it at 3% in the US, Canada at 2.4%, and Connecticut, Massachusetts and Maine have bans to clear with counsel.
Most of what ranks for this question is written by companies that sell surcharging, so it starts from the state list. I start from the invoice. A dealer told me they fight with customers about a card surcharge on account payments. On a $10,000 invoice, that fight wins you about $96 more than the alternative below.
I run ToolSwift, which sells online stores to distributors. Customers on those stores pay invoices through your own gateway (Stripe, VersaPay, Clover, Square or Moneris), and we take no transaction fees, so I earn the same whichever option you pick.
A customer who keeps paying a 3% surcharge is telling you about their cash, and that is worth more than the 3%.
This is not legal advice. Every rule below carries its date, because several changed recently.
Who should pay the card fee on a trade account?
You should pay it on small invoices, the bank should replace it on large ones, and the customer should see a surcharge only when both of those have failed. That order follows from what a card does on a trade account: it pays you now and lends your customer money for a few weeks, and you fund the loan.
So the fee is a symptom of how you sell credit. Decide who should pay by what method first, and the surcharge question mostly answers itself.
I have heard the card-fee fight from lumber and hardware dealers. I have not heard it from other trades, and that is the limit of my evidence. The arithmetic applies to any supplier with trade accounts.
What each way of paying does to a $10,000 invoice
Bank at full price keeps the most, if the account will move for nothing. Among the options that give it a reason, a surcharge keeps more for you and a 1% bank discount costs your customer less. The gap between them is the whole decision. I ran one $10,000 invoice through Square's published US rates, read November 2, 2026: 2.9% + 30 cents for a card and 1% with a $1 minimum and $5 cap for ACH, both through its online API. They are used because they are public. Your own rate will differ, and you should rerun this with it.
The surcharge beats the 1% bank discount by $96.29 for you. It costs your customer $390 more. That is a poor trade on an account you want next year.
The paper check line in the table below assumes the $2 top of the $1.01 to $2 median that AFP's 2022 survey puts on receiving one, and it ignores the wait. A small yard told me a check can take days in the mail from a customer some distance away.
Now price the speed. The Federal Reserve lists the bank prime rate at 7.00% for October 29, 2026. At prime, carrying $10,000 costs $1.92 a day, so the $290.30 card fee would carry that invoice for 151 days. Speed alone never justifies a card on a large invoice. What the fee can buy is certainty, on an account you would otherwise chase.
Look at it from the customer's side too. If a card gives them about 30 days of float, a 2.9% surcharge prices that float at 35% a year. Someone who keeps paying that is short of cash or chasing card rewards, and your credit manager should want to know which.
And check the fee against margin. At an illustrative 20% gross margin, $290.30 is 14.5% of the $2,000 profit on the order. On a thinner line it is worse.
What do Visa, Mastercard and the law allow?
Visa's US ceiling is 3%, the older 4% figure you still see is out of date for Visa, and your real limit is usually lower than either. The Visa Rules edition of October 24, 2026 sets a 3.00% maximum and also caps a brand-level surcharge at your average merchant discount rate over the prior one or 12 months. If your blended rate is 2.2%, your cap is 2.2%.
Four things catch B2B suppliers, and the table at the end of this section dates each limit.
A business sale is not a safe exit from a ban, and a ban does not clearly reach it either.Massachusetts says "no seller in any sales transaction." Colorado says "any sales or lease transaction." But Massachusetts c.140D section 2(a) and Maine 9-A section 1-202(1) exclude credit primarily for business purposes from the acts holding those bans. That does not settle whether the exclusion reaches a seller's surcharge on a trade account, so ask counsel before surcharging in either state. Maine also bans surcharges on debit, and says a discount from the regular price is not a surcharge.
Visa's own state list has aged. Its surcharge Q&A, dated February 15, 2024, lists Oklahoma as prohibiting surcharges. Oklahoma's SB 677 allows them from November 1, 2025, at the lesser of 2% or cost. Any list without a date is a guess.
A surcharge cannot be selective on Visa without care. Rule 5.5.1.7 applies the same surcharge to all Visa credit transactions, or to all of one product type, never both. Read literally, surcharging account payments and sparing counter sales sits awkwardly with that. Get your acquirer's answer in writing before you do it. Debit and prepaid are excluded, your acquirer needs 30 days' notice, and Visa says an acquirer can face an immediate US$1,000 fine for a merchant surcharging improperly.
The cap may leave you short. Visa's interchange table, effective October 24, 2026, goes up to 3.15% + $0.20 for Business Non-Qualified transactions, above its own 3% cap and before your processor's markup. In Canada the gap is wider. At Stripe's list price of 2.9% + C$0.30, a C$10,000 invoice costs C$290.30, and the 2.4% cap brings in C$240.
I could not open Mastercard's current rulebook, which refused my requests. The 4% rests on Goodwin's March 2025 summary and a Mastercard spokesperson quoted in April 2023. Confirm it with your acquirer.
In Canada, the rules come from the merchant settlement that took effect October 6, 2022. Visa's Canadian FAQ covers consumer and corporate credit cards. The Financial Consumer Agency of Canada says the customer must be able to cancel without penalty and pay another way, and it excludes Quebec. The Canada Revenue Agency ties that exclusion to Quebec's Consumer Protection Act, so whether a sale to a business falls under it is a question for your lawyer. The Competition Bureau argued in 2015 for merchants' freedom to price by payment method. That is advocacy, not a rule.
Why "no cards over $5,000" breaks Visa's rules today
A blanket card limit is prohibited on Visa for almost every supplier, though the fee-saving instinct behind it is sound. Section 5.4.2.3 of the Visa Rules lets only US federal agencies and schools with listed merchant codes set a maximum transaction amount, and federal law carves out the same two groups. Section 1.5.5.1 applies the ban to merchants generally. The US exception there is a credit card minimum of up to $10, plus those two groups.
The allowed version is asking. Section 1.5.4.11 lets a merchant request or encourage another payment method, and offer a discount for it. Federal law bars card issuers from prohibiting cash discounts, and a discount offered to all buyers and clearly disclosed is not a finance charge. So print "pay by bank and take 1% off" on the invoice over a threshold, and leave the card available. Visa's display rule matters here: the Q&A says a discount that looks like an added card fee may be treated as a surcharge.
A real way out may be coming. The amended settlement dated November 10, 2025 would let US merchants accept or decline all commercial credit cards, with 30 days' notice to the acquirer, within 90 days of approval. It would also set Mastercard's surcharge at the lesser of 3% or cost, matching Visa. Judge Cogan gave preliminary approval on June 9, 2026, and the final hearing was set for November 16, 2026. As of November 2, 2026, none of it is in force, and the convenience-store trade group NACS says it will appeal if the deal is approved.
Refusing a commercial card is still a blunt tool. My bet, 70/30: by the end of 2027 few independent distributors will decline commercial cards outright, because those cards sit with accounts they want to keep.
Where each option loses
Every option here loses somewhere, bank pay included. Pay by bank leaves the credit risk with you until the funds settle. Visa lists "guaranteed payment" among the benefits of card acceptance, and on a shaky account that is a real thing to give up for $285.
A discount costs margin on accounts that might have paid by bank anyway, and it has to be offered evenly to stay clean. Pricing it in is invisible until a competitor quotes without it, and your bank-paying accounts subsidize your card-paying ones. There is some precision to be had there: per-account pricing can reflect how an account pays, if your ERP holds the price. A reward for paying fast, as in a rewards program, gets at the same behavior from the other side.
The surcharge loses on the relationship. Visa itself calls it a practice that "penalizes cardholders", and on an account payment the penalty lands weeks after the price was agreed. That timing is what I think drives the fights.
The surcharge still wins in one case. If your margin is thin, your accounts are small and card-heavy, and none of them will move, it is the honest way to stop funding the loan.
You can also cut the fee itself before you pass anything on. Visa's table lists 2.70% + $0.10 for commercial cards not present and 1.75% + $0.10 for Commercial Product 3, so ask your processor what data your invoices would need to send, and whether your pricing passes the lower rate through to you. A flat-rate plan will not. Shrinking your acceptance list is cheap too. A plumbing business told me it keeps Visa and Mastercard because that is all its office accepts.
When paying online will not help
A pay-online button does nothing for an account that pays when it has cash. An LED supplier told me its customers pay in lump sums when cash allows, not per invoice. A portal gives those customers a nicer place to do the same thing. The fix for them is terms and a credit conversation.
If most of your accounts pay on time by check and your card volume is small, the honest answer is not yet. Put your bank details on the invoice and spend the effort elsewhere.
Online payment helps when the friction is the mail, the back office or a statement nobody can find. It will not change what a customer can afford this month.
My rule for deciding who pays the fee
Run these in order, and stop at the first one that fits.
- Late payer: treat it as a credit problem. Fix terms before you touch card fees.
- Large invoice: ask for bank payment, and offer up to 1% if you must. On the list rates above, 1% plus the ACH fee beats the card on anything over about $37, so the threshold is really about whose habit is worth changing. I would start at $2,500, where you save about $43 an invoice. That line is my judgment, not data.
- Small invoice: absorb the fee or price it in. A surcharge fight over $14.80 on a $500 invoice costs more than $14.80.
- Still card-heavy, thin margin, and legal where your outlet sits: surcharge, at no more than your actual rate, on every Visa credit transaction alike, with the notice filed and the disclosure posted.
Surcharge last. It is the only option on this list your customer reads as a penalty.
Where ToolSwift fits
ToolSwift barely touches who pays the fee, because that policy is yours and the rate is between you and your processor. What it does is give customers a place to see what they owe and pay statements and invoices themselves, by card, ACH or from their bank, through your own gateway. ToolSwift takes no transaction fees on those payments. It applies each payment to the right invoices, in full or in part, and keeps the records in step with your ERP. If the mail and the back office are your friction, book a demo.
FAQ
Can you add a credit card surcharge to a business customer?
Yes in most US states and in Canada outside Quebec, within the network caps. Connecticut, Massachusetts and Maine ban surcharges. The Massachusetts and Maine acts exclude business-purpose credit, so counsel must confirm whether those bans reach a trade account. Have counsel confirm your states.
Is the Visa surcharge cap 3% or 4%?
Visa's US maximum is 3.00%, per the Visa Rules dated October 24, 2026. Visa cut it from 4% on April 15, 2023, per Payments Dive. The 4% figure belongs to Mastercard in the US, per a 2025 law firm summary. Your own limit is lower if your average discount rate is lower.
Can you surcharge debit cards?
No. Visa's rules limit surcharges to credit cards in the US and Canada, and exclude debit and prepaid. Colorado's statute also excludes debit.
Is a cash discount the same as a surcharge?
No, as long as it is built as a discount from the price. Visa requires the card price per item, or card and cash prices side by side. A discount presented as an added card fee at the end may be treated as a surcharge.
Can a supplier refuse cards above a certain amount?
Not on Visa today, apart from US federal agencies and certain schools. The pending settlement would let US merchants decline all commercial credit cards as a category. It would not allow a dollar limit by itself, on my reading.
