Risk Control Shield | 2025 Black Friday Cyber Monday Report Released: After the Frenzy, Did Your Wallet Arrive “Safely” Home?
2025年12月15日While families were unwrapping gifts, some cross-border merchants were unwrapping an unexpected “bill”—a mountain of chargeback notices.
Last month, a cross-border e-commerce company specializing in jewelry just finished its monthly performance review. The report showed that the company’s revenue increased by 65% year-on-year during the peak sales season, but net profit actually decreased by 12%.
The problem lies in the unseen costs: in November alone, direct losses due to fraudulent transactions and customer disputes exceeded $180,000, not including human processing costs, payment platform fines, and working capital frozen as a result.

This is not an isolated case. According to data, the average monthly chargeback rate during the Christmas season is 2.3 times higher than usual, with more than a quarter of these chargebacks coming from “friendly fraud”—where customers receive the goods and then refuse payment while keeping the goods, citing reasons such as “not received” or “goods not matching the description.”
The Christmas shopping season brings not only a surge in orders, but also a complex and costly system of risks. Merchants face losses far exceeding the amount of refunds.
Direct profit erosion, the iceberg effect of non-payment
Every malicious chargeback means that the merchant loses product costs, logistics costs, platform transaction fees, and marketing costs.
For categories like Christmas gifts and electronic accessories, which already have low profit margins, a single large fraudulent order can wipe out the profits of dozens of legitimate transactions.
Even more serious is the fact that high chargeback rates can trigger penalty mechanisms from payment service providers and card organizations. For example, if a merchant’s Visa VAMP consistently exceeds the limit, they may face tiered penalties, and in severe cases, even suspension of payment privileges. This means that merchants may lose not only orders but also the ability to collect payments for the entire Christmas season.
Fraud costs are soaring, putting operations in a dilemma.
To combat fraud risks, merchants often need to invest a lot of manpower, and even go so far as to conduct 24-hour order verification.
A mid-sized seller revealed that they need to hire eight additional temporary risk control auditors during the Christmas season, increasing their monthly labor costs by nearly $50,000.
However, manual review faces a dilemma: if the review is too strict, it will inadvertently reject a large number of legitimate orders, leading to a decrease in conversion rates and customer loss; if the review is too lenient, it will allow fraudulent orders to slip through.
During peak order periods, it is difficult for humans to make accurate judgments, and they often have to rely on simple monetary or regional rules, which has very limited effectiveness.
Long-term asset damage, reputation and cash flow crisis
Risk losses not only affect current financial statements. Once a merchant is placed on the monitoring list of a payment platform or card organization due to excessively high risk indicators, their ability to collect payments through all channels will be restricted in the future, and their brand reputation will be severely damaged.
Furthermore, numerous disputes can lead payment service providers to extend settlement cycles or freeze some funds as security deposits, directly impacting merchants’ cash flow for inventory preparation and marketing, creating a vicious cycle.

Breaking the deadlock: Intelligent risk control protects profits
Faced with the unique risks of the Christmas season, traditional risk control rule engines and manual review are no longer sufficient.
Among Wintranx’s clients, we have observed that the risks associated with peak sales seasons typically exhibit three characteristics:
- Automated attack detection (fraudulent groups using scripts for batch testing) provides precise identification, rather than a one-size-fits-all approach. Wintranx’s risk control engine can analyze hundreds of behavioral characteristics within milliseconds, without relying on a single rule. For example, the system can distinguish between legitimate users who “buy multiple different gifts for family members” and fraudulent groups who “test the same product with multiple cards,” avoiding the false positives of valuable Christmas season orders.
- The system dynamically adapts to holiday-related cancellations (resulting in more “gift not received” disputes). It incorporates a built-in Christmas season risk model that automatically detects and adjusts strategies at different stages: preventing black market card testing during the pre-sale period, monitoring for abnormal logistics orders during peak periods, and guarding against “holiday regret” chargebacks later on. All of this is done automatically in the backend, eliminating the need for merchants to manually adjust complex rules.
- Proactive management of “window period” attacks (concentrated during peak logistics times and slowest customer service responses), rather than just passive interception. Risk control’s endpoint is not transaction rejection. We integrate solutions such as 3DS 2.0 verification and Visa CE 3.0 (strong evidence) to help merchants avoid transaction disputes; simultaneously, when disputes arise, we quickly submit evidence such as logistics receipts and historical transaction records to defend against them, mitigating some losses before they occur. Professional risk control should act like an invisible escort, ensuring route safety without impacting the sailing experience. Its value is readily apparent.
A cross-border merchant who introduced Wintranx last year reduced its chargeback rate from 3.8% to 0.9% while maintaining a 60% increase in order volume. This not only directly saved over $250,000 in losses, but more importantly, its stable risk control performance earned it more favorable rates and settlement cycles from payment partners, improving overall capital efficiency by nearly 15%.
The essence of the Christmas sales season is the transmission of trust and joy. Buyers trust merchants to deliver the perfect gift on time, and merchants trust that transactions will be completed smoothly. Fraud, chargebacks, and abuse are eroding this foundation.
Risk control isn’t about building high walls, but about repairing and defending that trust. It ensures that every toy given to a child, every blessing sent to a family, can smoothly deliver its value; and that every diligent business’s efforts receive the rewards they deserve.
