The central issue for mid-market merchants is that transaction fraud creates costs well beyond the disputed payment itself. A single chargeback can mean lost goods, processor fees, hours of staff time pulling evidence, delayed refunds, compliance scrutiny, and a harder-to-forecast cash position — costs that compound as transaction volume grows.
Cross-border commerce between U.S. technology hubs and Canadian markets like Ontario represents a substantial and growing economic relationship. Two-way trade in goods and services between the two countries totaled $917.4 billion in 2024, with cross-border commerce averaging more than $2.5 billion per day, according to the U.S. International Trade Administration (Trade.gov, “Canada – Market Overview,” 2024 data). The physical movement of that trade is also expanding: the U.S.-Canada cross-border freight transport market — the logistics layer that underlies much of this commerce — is projected to grow from $67.31 billion in 2026 to $79.65 billion by 2031, a 3.42% compound annual growth rate, driven in part by resilient consumer spending and tightening rule-of-origin requirements under CUSMA (Mordor Intelligence, “US-Canada Cross-Border Freight Transport Market,” 2026). Within that volume, a meaningful share still moves through mismatched checkout setups, where a phone order taken through a virtual terminal carries different risk coverage than the same transaction completed online. That inconsistency has a quiet cost: fraud exposure that erodes margin long before it shows up on a quarterly statement.
Worldwide card fraud losses came to $33.41 billion in 2024, a slight decline from $33.83 billion the year before, against total global card volume of roughly $51.9 trillion, according to the Nilson Report (2025 global card fraud data release), a payments-industry trade publication. The U.S. share of that exposure is disproportionate: it accounted for about 26% of global card volume in 2024 but absorbed nearly 42% of fraud losses worldwide, a gap the report ties largely to the country’s heavy reliance on card-not-present transactions — the e-commerce and phone/mail-order channels where fraud is hardest to screen. The Nilson Report projects global losses will climb to roughly $41 billion by 2030 as transaction volume keeps growing faster than fraud-fighting tools can fully offset.
The True Cost of a Chargeback
For a mid-market merchant, a single disputed transaction rarely ends with the refunded amount. There’s the processor’s chargeback fee, typically charged regardless of outcome. There’s the lost inventory if the product already shipped. There’s staff time spent compiling evidence — order records, shipping confirmation, customer correspondence — to contest the dispute, work that often falls to whoever is available rather than a dedicated fraud team. And disputes that are mishandled or contested too slowly can trigger closer scrutiny from card networks, adding a compliance burden on top of the financial loss.
Friendly fraud, where a cardholder disputes a charge they actually authorized, has become a growing concern for merchants that lack dedicated dispute-management resources. Mastercard’s 2025 State of Chargebacks Report estimates that global chargeback volumes will rise from roughly 261 million in 2025 to 324 million by 2028 — a 24% increase in three years — driven in part by the continued growth of digital commerce and the difficulty issuers face distinguishing genuine fraud claims from disputes over legitimate purchases. That gap is more pronounced at the mid-market level than among larger retailers with in-house fraud teams.
Where Checkout Infrastructure Falls Short
Much of this exposure traces back to infrastructure decisions made years before fraud patterns evolved. Many mid-market merchants run payment stacks assembled piecemeal — a checkout plugin here, a gateway integration there, layered onto e-commerce platforms that were never built with transaction-level risk scoring in mind. A merchant might run modern fraud screening on their online store while phone and mail orders route through an older virtual terminal with no equivalent screening at all, leaving one of the riskiest channels with the least protection.
EMV certification adds another layer of complexity. EMVCo, the global technical body that owns and manages the EMV chip and payment-tokenization specifications, requires processors and payment software to pass interoperability and security testing before they can support chip-based and tokenized transactions (EMVCo, “What are the EMV Specifications?” emvco.com, 2026). Running outdated systems risks both certification lapses and gaps in fraud coverage. Security auditing is often inconsistent across these fragmented stacks, since no single vendor owns the full path from checkout to settlement. And risk oversight tends to be reactive — merchants reviewing chargeback reports after the fact rather than flagging unusual transactions as they happen. Each gap is manageable on its own; together, they create an environment where fraud exposure can grow faster than revenue.
The Cross-Border Layer
Selling across the U.S.-Canada border adds complexity that domestic-only merchants don’t face. Currency conversion timing can affect the amount a merchant actually nets on a sale, particularly when exchange rates shift between authorization and settlement. Settlement schedules and banking relationships also differ between the two countries, which can affect how quickly funds clear. Issuing banks on either side of the border may apply different standards for what counts as sufficient documentation in a dispute, and consumer protection rules aren’t identical between U.S. and Canadian card networks — a difference that can affect how a chargeback gets resolved. For a merchant managing all of this manually, the administrative load of selling into both markets is its own quiet drain on staff time, separate from fraud itself.
A Shift Toward Consolidated Infrastructure
The response from the payment technology sector has been a gradual shift toward API-driven infrastructure that builds fraud controls into the processing layer itself, rather than adding them on top of checkout after the fact. Much of this shift is framed around supporting PCI DSS, the data security standard maintained by the PCI Security Standards Council (PCI SSC), the industry body — founded by the major card networks — that sets baseline technical and operational requirements for protecting cardholder data (PCI Security Standards Council, pcisecuritystandards.org, 2026). RapidCents, a Canadian-founded payment processing technology provider based in the Toronto area, is one example of a company positioned within this shift: according to the company’s own published materials, its platform includes automated chargeback-management tools, real-time fraud monitoring, and security controls described as supporting PCI DSS compliance (RapidCents, rapidcents.com, 2026). Vendors taking this approach generally aim to apply the same screening to manually keyed transactions — phone and mail orders — that they apply to online checkout, rather than treating those channels as lower-scrutiny by default.
Whether a given vendor delivers on that consolidation in practice is something individual merchants need to evaluate against their own transaction mix, but the underlying direction — fewer disconnected tools, more unified risk visibility — reflects where the broader payments industry is heading.
Key Takeaways
- Payment fraud creates costs beyond the disputed transaction itself — fees, lost inventory, staff time, and compliance scrutiny all add up.
- Mid-market merchants tend to be more exposed than larger retailers because their payment systems are often fragmented and under-resourced for dispute management.
- Cross-border U.S.-Canada commerce adds settlement, currency, and documentation complexity that purely domestic merchants don’t face, on top of one of the largest bilateral trade relationships in the world.
- API-driven fraud monitoring and automated chargeback workflows, generally built to support PCI DSS and EMV/tokenization standards, are becoming a more common response — though merchants should evaluate any vendor’s specific capabilities rather than assume uniform coverage.
Conclusion
As cross-border commerce between markets like Ontario and major U.S. commercial centers continues at scale, the mid-market merchants best positioned to protect margin will be those that treat fraud mitigation, dispute management, and compliance as core parts of their payment infrastructure — not as problems to solve after a chargeback has already landed. The path forward is less about any single vendor and more about closing the gaps that fragmented checkout systems leave behind: unifying fraud screening across online and manually keyed channels, building faster evidence-collection workflows for disputes, and treating compliance as an ongoing operational function rather than a once-a-year certification exercise.
