TAMPA, Fla. — Cyber Week may be over, but for credit unions, the riskiest stretch of the holiday shopping season is just beginning. Industry analysts are warning that the largest wave of payment disputes and chargebacks often hits after the buying frenzy fades, creating delayed operational and fraud pressures for financial institutions.
Early indicators point to a strong holiday season, with online sales projected to top $253 billion, driven increasingly by mobile commerce, which is expected to account for more than half of all digital transactions. Buy Now, Pay Later usage also continues to climb, reshaping how consumers manage holiday spending and introducing more complex payment flows that can complicate dispute resolution for card-issuing institutions.
As transaction volumes rise, so does the likelihood of post-purchase disputes—many initiated not by criminal fraud but by so-called “friendly fraud.” Consumers frequently challenge charges when a merchant descriptor looks unfamiliar, shipping is delayed, or refunds take longer than expected. With banking apps enabling near-instant disputes, these claims often surface weeks after the holidays, landing squarely on credit unions’ card-services and fraud teams well after peak shopping volumes have subsided.
The post-holiday dispute surge underscores a growing challenge for credit unions: balancing fast, member-friendly dispute handling with rising operational costs, increased chargeback exposure, and more complex payment behaviors that extend far beyond the checkout screen, pointed out Chargebacks911.
Chargebacks911 Founder and CEO, Monica Eaton, said retailers should not assume the end of Cyber Week signals the end of risk.
“Customers are buying quickly and resolving issues even faster,” said Eaton. “When something feels off, many people tap their banking app before checking their order history or contacting the retailer. Without strong post purchase processes, merchants lose revenue they worked hard to earn.”
Eaton notes that holiday disputes often follow predictable patterns. Delayed shipments, late night impulse purchases, mismatched billing names and refund impatience play a significant role in driving friendly fraud cases each December. These patterns accelerate each year as digital buying habits become more ingrained.
Chargebacks911 recommended that merchants take immediate steps to protect holiday revenue. Clear billing descriptors, proactive shipping updates, transparent refund timelines and real time dispute alerts can dramatically reduce preventable chargebacks. The company also advises merchants to review their dispute ratios weekly throughout December and January and to deploy tools that prevent accidental double refunds and ensure banks receive complete and accurate evidence.
“Preparation is the strongest defense,” Eaton added. “Retailers that reinforce their post purchase experience now will safeguard more of their holiday profits and start the new year in a stronger position.”
Chargebacks911 warned that dispute volume typically increases in early January as cardholders review their statements and holiday spending settles.
