A convenience fee is a charge for using an alternative payment channel (pay-by-phone, a web portal) instead of the merchant's customary way to pay. A surcharge is a charge for paying by credit. Visa's public FAQ requires a U.S. convenience fee to be a flat fee, not a percentage, clearly disclosed, and charged for that alternate channel. Core Rules Table 5-5 (April 2026 public edition) adds the tests: card-absent only, not if you are online-only, same fee on every tender in that channel, one authorization, never stacked on a surcharge. A U.S. credit surcharge is a different program: credit only, capped at the lower of your merchant discount rate or 3 percent, with 30-day acquirer notice. Calling a 3 percent card add-on at the register a "convenience fee" does not convert it. Mixing the two is how programs get shut off.
This is a comparison of brand rules, not legal advice. Confirm the current text with your acquirer and counsel.
- Fee for an alternative channel (phone, web), not for the card
- Visa: flat or fixed amount, not a percentage
- Same fee on every tender accepted in that channel
- Card-absent only; not if you are online-only
- Cannot stack on a surcharge
- Fee for paying by credit, on a posted price
- Visa cap: lower of merchant discount rate or 3 percent
- Credit only; never debit or prepaid
- 30-day acquirer notice plus entry, POS, and receipt disclosure
- State law can ban it even when the brand allows it
What a convenience fee actually is
Visa treats convenience fees in Core Rules section 5.5.2 (Table 5-5, ID 0027492). For the U.S. region, every row is required:
- Charged for a bona fide convenience: an alternative channel outside your customary channels, not charged solely for accepting a card.
- Added only on a card-absent sale (phone, mail, web). Not face-to-face.
- Not charged if you operate exclusively card-absent. A web-only business has one channel, not an alternative.
- Charged only by the merchant that provides the goods or services. A third party billing the fee as its own sale fails this row.
- Applicable to all forms of payment accepted in that channel. Cards and ACH in the portal both pay it. A portal fee that hits only cards is not a convenience fee.
- Disclosed as a channel charge before the customer pays, with a chance to cancel.
- A flat or fixed amount, regardless of the payment due.
- Included in the total transaction amount, not collected as a second sale.
- Not charged in addition to a surcharge, and not charged on a recurring or installment transaction.
Mastercard Rule 5.12.2 draws the same line in different words. A surcharge is any fee charged on a transaction that is not charged if another payment method is used. A convenience-type fee is allowed if it is imposed on all like transactions regardless of the form of payment, or if Mastercard has permitted it in writing. If ACH in the portal is free and the card is not, that is already a surcharge under Mastercard's definition.
The channel test is the product. A clinic that still takes payment at the desk can charge a disclosed flat fee on the patient portal, on every tender the portal accepts. A retailer whose only checkout is a website cannot relabel card cost as convenience. There is no alternative to be convenient.
What a surcharge actually is
A surcharge is an extra amount added because the customer pays with credit. Visa's U.S. credit surcharge (small-business regulations page and the February 15, 2024 Merchant Surcharge Q and A) requires:
- Credit only. Debit and prepaid cannot be surcharged, including when the customer taps "credit" on a PIN pad.
- A cap at the lower of the merchant discount rate for that credit card or 3 percent.
- Notice to the acquirer at least 30 days before the first surcharged sale.
- Disclosure at entry, at the point of sale, and as a separate receipt line.
Mastercard's U.S. merchant surcharge page (settlement effective January 27, 2013) is the same shape: not allowed on Debit Mastercard or prepaid, 30-day notice, brand-level or product-level, and a cap tied to cost of acceptance. Mastercard publishes a Maximum Surcharge Cap of 4 percent. Cost of acceptance can still bind below that number, the same way Visa's 3 percent ceiling still yields to a lower discount rate.
State law sits on top of both brands. Connecticut, Massachusetts, and Maine still prohibit a credit-card surcharge in current statute. Visa's February 15, 2024 Q and A also lists Puerto Rico as a prohibition. Is surcharging legal in your state in 2026 is the decision sequence. A surcharge ban is not a convenience-fee license. If the extra amount exists because of the card, it is still a surcharge, whatever the sign says.
Surcharge, dual pricing, and cash discount are other ways to shift card cost. None of them is a convenience fee. Dual pricing posts two prices. A cash discount subtracts from a posted price. A convenience fee charges for a channel.
Where the labels get mixed
The failure mode is a percentage added at checkout and sold as "convenience." Run the substance, not the name.
Percentage at the register. Visa convenience fees are flat and card-absent. A 3 percent add-on in a face-to-face lane is a surcharge. It then inherits credit-only treatment, the 3 percent-or-discount cap, 30-day notice, and any state ban. Visa's February 15, 2024 Q and A says the acquirer of a merchant identified as surcharging improperly may be assessed an immediate $1,000 fine.
Card-only "convenience" online. Visa requires the fee on every tender in the channel. Mastercard Rule 5.12.2 treats a fee that disappears when the customer uses another method as a surcharge. A web checkout that adds $4.95 only on cards is a card fee wearing a channel name.
Two authorizations. Visa requires the fee inside the same transaction total. Splitting the invoice and the fee into two sales misses Table 5-5.
Stacking or recurring. Visa forbids a convenience fee in addition to a surcharge, and forbids it on recurring or installment transactions. A portal fee that keeps billing with a subscription fails even if the first payment was a one-time card-absent sale. Pick one program.
Worked example (illustrative)
Numbers below are illustrative. They show the tests, not a quote.
A clinic's customary payment is at the front desk. The posted visit is $200. The clinic also offers a patient portal.
- Front desk, debit: $200. No convenience fee (not card-absent). No surcharge on debit.
- Front desk, credit, legal surcharge, discount rate 2.40 percent: Visa's cap is the lower of 2.40 percent and 3 percent, so 2.40 percent. Surcharge = $200 × 0.0240 = $4.80. Total $204.80. A flat 3 percent toggle would add $6.00 and overshoot the discount rate.
- Portal, true convenience fee: a disclosed $5.00 flat fee on every tender the portal accepts, with a cancel path, inside one authorization. Debit, credit, and ACH in the portal all pay $205. You cannot also surcharge that Visa portal sale.
- Portal, mislabeled: $5.00 only on cards, ACH free. That is a card fee under both Visa Table 5-5 and Mastercard Rule 5.12.2.
Same $200, two lawful shapes, two illegal ones. The question you are charging for is the channel, or the card.
A third bucket: service fees
Visa also runs a service-fee program (Core Rules section 5.5.3). A U.S. service fee is limited to listed merchant category codes: government, education, and utilities among them (Table 5-6). Visa's public FAQ allows those merchants to assess fixed or variable service fees, the percentage path convenience fees do not have. Mastercard's U.S. surcharge FAQ describes a separate convenience-fee program for participating pre-certified government and education entities (or their third-party agents). That is closer to Visa's service-fee bucket than to a retailer's pay-by-phone fee. A restaurant or clinic is not in it because it renamed a line item.
Visa says a service fee is not charged in addition to a surcharge or a convenience fee. Three names, at most one of them on a given sale, and only if the MCC and the channel qualify.
How to choose without stacking
Ask four questions in order. The first "no" ends the convenience-fee path.
- Is there a customary channel the customer could still use? If every payment is already web or phone, Visa says you do not get a convenience fee.
- Is this sale card-absent? A register or a card-present tap is not an alternative channel.
- Is the amount flat, disclosed before submit, cancelable, and charged on every tender in that channel, inside one authorization? If any of those is missing, stop calling it a convenience fee.
- Are you also surcharging credit? If yes, you cannot add a convenience fee on that brand's sale. Run the surcharge as a surcharge: credit only, capped, noticed, disclosed. Confirm the outlet's state first.
If the goal is recovering card cost on ordinary retail volume, you are in surcharge, dual pricing, or cash-discount territory. If the goal is charging for a phone or portal that actually replaces a walk-up payment, a flat, tender-neutral convenience fee is the shape Visa wrote down.
To see whether a 3 percent add-on is even close to your credit discount rate, run a statement through the analyzer and use the as-billed credit cost as the ceiling before anyone flips a toggle.
FAQ
What is the difference between a convenience fee and a credit card surcharge? A convenience fee is a charge for using an alternative payment channel, such as pay-by-phone or a web portal, instead of the merchant's customary way to pay. A surcharge is a charge for paying by credit. Visa requires the U.S. convenience fee to be a flat amount for the channel, not a percentage for the card.
Can I charge a percentage convenience fee? Not under Visa's U.S. convenience-fee table. The fee must be a flat or fixed amount, regardless of the payment due. A 3 percent add-on for using a card is a surcharge (or a service fee, if you are in Visa's MCC-limited service-fee program), not a convenience fee.
Can I charge a convenience fee and a surcharge on the same sale? No on Visa. Table 5-5 says a convenience fee is not charged in addition to a surcharge. Mastercard's U.S. surcharge FAQ treats its convenience-fee program as a separate government and education track, not a second fee on a retail credit surcharge. Pick one program.
Can I add a convenience fee at the register when someone pays with a card? No. Visa limits a U.S. convenience fee to a card-absent transaction on an alternative channel, and forbids it if you operate only in a card-absent environment. A card fee at a face-to-face register is a surcharge, with credit-only, cap, notice, and state-law tests.
Do convenience fees apply to debit cards? A true convenience fee applies to every form of payment you accept in that alternative channel, debit included. A fee that hits only cards, or only credit, is not a convenience fee. Surcharges, by contrast, may never be applied to debit or prepaid.
Do I have to notify Visa 30 days before charging a convenience fee? The 30-day acquirer notice is a surcharge rule, not a convenience-fee rule. You still have to configure the fee so it matches Visa's channel tests, and you still confirm state law and your acquirer. Using the wrong label does not skip surcharge registration.
