The platform opportunity in surcharging

Merchants are asking for relief from card costs. Platforms that answer well turn surcharging into adoption, retention, and revenue.

For years, the platform payments playbook was straightforward: embed payments, improve the user experience, and earn a share of the economics. That opportunity remains enormous. But as embedded payments mature, platforms are confronting a harder question: how do they continue to grow payments revenue while also improving the economics for the merchants they serve?

Productized credit card surcharging is becoming one approach. It allows merchants to compliantly pass on credit card processing fees, and this strategy also gives the platform a new tool to drive payment adoption, retention, and monetization.

The opportunity is real, but so is the risk of treating it casually. The platforms that win will approach surcharging as an initiative across product, pricing, compliance, and go-to-market strategy, not simply as adding a toggle in the payment flow.

Why surcharging is moving into the mainstream

The underlying pressure is not difficult to understand. The Nilson Report reported that U.S.-issued cards generated $11.9 trillion in spending volume, with credit cards accounting for 54% of the purchase volume in 2024. In the US, merchants paid a record $187.2 billion in associated card-processing fees, including approximately $148.5 billion tied to credit cards specifically. For a small or midsize business operating on thin margins, a two-to-three-percent acceptance cost can be one of the largest variable expenses in the business.

Merchants are responding. J.D. Power’s 2026 U.S. Merchant Services Satisfaction Study found that 35% of U.S. small businesses now apply credit card surcharges. That is no longer a fringe behavior. Surcharging infrastructure is becoming a mainstream merchant need, and it increasingly surfaces in platform sales conversations, user communities, support requests, and competitive evaluations.

Why this is a platform problem, not just a merchant problem

BCG describes vertical SaaS platforms as de facto operating systems for many small and midsize businesses. U.S. SME adoption of vertical software reached 59% in 2024, while more than half of relevant North American software vendors offered embedded payments in 2025.

That changes merchant expectations. A business owner does not experience card-processing costs as an abstract credit card interchange issue. The cost appears inside the SaaS platform they use to schedule work, send invoices, collect payments, and reconcile revenues. When that cost becomes painful, the merchant looks to the platform for an answer.

If the platform cannot provide one, the merchant may route a payment outside the platform, steer customers toward a different workflow, or choose a competitor that offers more control over payment economics. In that sense, surcharging is as much a payment-volume protection and merchant-retention tool as it is a cost-recovery feature.

The value stack for platforms

The business case is bigger than the surcharge line item. A well-designed program creates value at four levels:

Better merchant economics. Eligible merchants can recover a meaningful portion of their credit card acceptance costs rather than absorbing the entire expense in their margin.
More volume stays on-platform. Giving merchants a viable way to manage card costs reduces the incentive to collect payment elsewhere.
Stronger payments adoption and retention. Surcharging can make the platform’s payments product more attractive to new merchants and more valuable to existing ones.
Create incremental revenue. Platforms can package, price, or share in the economics of the capability, provided the model does not suppress adoption or undermine customer trust.

This is the strategic shift: a platform should not evaluate surcharging only by asking, “How many basis points can we add?” The better question is, “Which model maximizes total platform value across payments volume, merchant adoption, tier upgrades, retention, and direct revenue?”

A successful rollout is a go-to-market program

Most surcharging launches do not fail because the calculation endpoint is unavailable. They stall because the platform has not answered the operational questions around it: Which merchants are eligible? How will the feature be positioned? Who explains it? What happens when an cardholder objects? Which metrics determine how the pilot expands?

A disciplined platform rollout typically includes:

Segmented eligibility. Start with merchants and jurisdictions where demand is strong, the use case is clear, and the customer experience can be supported.
A willing pilot cohort. Launch with a manageable group, often 20 to 50 merchants, before expanding by state, vertical, merchant size, or product tier.
Merchant education. Provide plain-language guidance on eligible payment methods, caps, required disclosures, refunds, customer communications, and lower-cost alternatives such as debit or ACH.
Sales and support readiness. Train customer-facing teams to explain the value, address objections, troubleshoot configuration, and route true payment-processing issues appropriately.
End-customer communication. Give customers advance notice, especially for recurring billing and saved payment methods: and show the surcharge before payment is submitted.
A measurement plan. Track merchant attach rate, the share of eligible credit volume surcharged, payment-volume retention, support volume, checkout abandonment, disputes, merchant satisfaction, and 90-day retention.

The customer-experience consideration is not optional. The best programs don’t frame the choice as “pay an extra fee or leave.” They make it understandable: the credit card price is clearly disclosed, lower-cost alternatives are visible, and the merchant can explain why the program exists. Compliance and customer experience reinforce each other.

Compliance is dynamic and increasingly tied to state-specific regulations

At the network level, Visa’s U.S. merchant guidance limits surcharging to credit cards, prohibits it on debit and prepaid cards, caps the surcharge at the lower of the merchant’s applicable cost of acceptance or 3%, and requires disclosure at entry, checkout, and on the receipt. Other networks have their own rules, and those requirements can change.

State requirements add another layer. New York law requires the total credit card price, inclusive of the surcharge, to be posted clearly and caps the surcharge at the business’s cost. Louisiana’s 2026 legislation separately codifies a ban on additional fees for debit card use beginning August 1, 2026, even though card-network rules already prohibit debit surcharging. Broader state “junk fee” and all-in pricing rules are also pushing businesses toward earlier, clearer disclosure.

The rules are not static. Mastercard, for example, has long required merchants to notify it (and their acquirer) at least 30 days before surcharging credit cards. As of mid-2026, Mastercard has suspended that registration requirement while it rewrites its surcharging rules, including the notification and registration process, with revised rules expected in the second half of 2026. It’s a small but useful example of the operational burden platforms inherit: every change must be detected, interpreted, translated into product logic and merchant guidance, tested, and deployed across the merchant base.

For a single merchant, that work is demanding. For a platform supporting thousands of merchants across jurisdictions, it becomes infrastructure. The platform needs a reliable way to identify card funding type and geography, apply the strictest relevant rule, isolate configuration by merchant, produce the correct disclosure and ledger entries, and refund the surcharge proportionally when the underlying transaction is refunded.

What platforms need to consider before building or partnering

A platform evaluating surcharging should look beyond the calculation itself. A production-grade solution needs to address at least the following:

Real-time card-brand, funding-type, and jurisdiction decisioning.
Per-merchant rates, eligibility, locations, and rule isolation.
Support for one-time, invoice, saved-card, recurring, and in-person payment flows.
Accurate authorization, capture, refund, and partial-refund treatment.
Checkout, invoice, receipt, and customer-notice disclosures.
Registration or notification workflows where required.
Ledgering and reporting that distinguish principal, tax, surcharge, platform fees, and refunds.
Fallback behavior, monitoring, support ownership, and ongoing rule updates.

You can build all of that. But then you own the ongoing legal and network monitoring, merchant enablement, implementation quality, and change management, forever. For most platforms, none of that is a differentiator. The advantage is offering surcharging well, not just owning the rule engine underneath it.

The bottom line

Surcharging should not sit in a roadmap as an isolated compliance feature. It belongs inside the platform’s broader payments and revenue-optimization strategy.

Done thoughtfully, it helps merchants recover value, keeps payments inside the platform, creates room for premium packaging and new revenue, and makes the platform more responsive to a problem merchants are already trying to solve. Done poorly, it can limit adoption, confuse or surprise cardholders and create regulatory and reputational exposure.

The difference is not the presence of a surcharge line item. It is the infrastructure, pricing discipline, merchant education, and customer experience behind it.

FAQ

Is credit card surcharging legal? In most U.S. states and Canadian provinces, yes, when it follows card-network rules and judicial law. A small number of jurisdictions restrict or effectively prohibit it, and several (like New York) impose specific disclosure and pricing requirements. Compliance depends on where the merchant operates and how the surcharge is presented, which is why jurisdiction logic is best be built into the product, not just left to each merchant for interpretation.

Which cards can be surcharged? Credit cards only. Network rules prohibit surcharging debit and prepaid cards, even when a debit card is run “as credit.” That means the platform needs real-time card funding-type detection at the moment of payment, not a merchant-configured flag.

How much can a merchant surcharge? Under network rules, the surcharge is capped at the lower of the merchant’s cost of acceptance or 3%. Some states cap it lower or tie it strictly to actual cost. The safe answer for a multi-state merchant base: apply the strictest applicable rule automatically.

Do merchants have to disclose the surcharge? Yes, at the point of entry, at checkout, and on the receipt. Some states require the full credit price to be posted up front. Clear disclosure isn’t just a compliance requirement; it’s what keeps customers from abandoning the purchase or later disputing the charge.

What happens to the surcharge on a refund? It has to be refunded proportionally with the underlying transaction, including partial refunds. This is one of the most common gaps in homegrown implementations, and it has both compliance and accounting consequences.

Can a platform make money on surcharging? It depends. Platforms that white-label payments can package surcharging into premium tiers, price it as a feature, or share in the economics. The right model is the one that maximizes total platform value – adoption, volume retention, and upgrades – not the one that extracts the most basis points.

Should we build surcharging in-house or partner? Building means owning real-time decisioning, per-merchant configuration, disclosures, refund logic, ledgering, and permanent monitoring of network and state rule changes across your entire merchant base. Most platforms partner, because the differentiation is in offering the capability well inside their product, not in maintaining the rule engine.

How long does it take to launch? With the right implementation strategy, a pilot can be live in weeks: platforms should pick a willing cohort of 20-50 merchants, enable them in eligible jurisdictions, measure attach rate and customer response, then expand.
