TL;DR: Digital commerce brands lost an estimated $48 billion to fraud in 2025, while refund and policy abuse displaced payment fraud as the top merchant threat and every confirmed dollar now costs U.S. merchants $5.13, according to Sift and the Merchant Risk Council. Rules and manual review cannot keep pace with automated fraud rings that probe, adapt, and return at scale.
Editorial analysis by NHI Mgmt Group, based on content published by Sift: “Fraud Prevention For Digital Commerce And Retail Ecommerce Brands”.
By the numbers:
- For every dollar of confirmed fraud, U.S. merchants now absorb $5.13 in total cost.
Key questions
Q: What breaks when refund abuse is handled only with payment fraud rules?
A: Payment-only rules miss the post-purchase loss path.
Q: Why does refund fraud create so much operational risk for merchants?
A: Refund fraud drains cash, ties up support and finance teams, and forces merchants to spend time investigating claims instead of serving customers.
Q: What are the signs that refund abuse controls are failing?
A: Common signs include long manual review queues, repeated agent overrides, rising refund disputes, and too many customers asking why their order was held or cancelled.
Practitioner guidance
- Map fraud controls to the full customer journey Cover account creation, login, checkout, post-purchase service, refund handling, and loyalty redemption in one control model so abuse is not hidden between teams.
- Replace rule-only logic with layered risk scoring Use device reputation, behavioral signals, network patterns, and historical account trust together so adaptive fraud rings cannot learn one rule set and bypass it.
- Limit refund and policy exception authority Require stronger review for unusually generous refunds, repeat returners, and manual overrides that create a high-loss path without a matching trust signal.
Bottom line: Refund and policy abuse has become a lifecycle problem for ecommerce, because merchants can be exploited after the checkout moment as easily as before it.

Refund abuse is now an identity and trust problem, not just a payments problem. The article shows that merchants are being attacked across account creation, login, checkout, and post-purchase workflows, which means the control boundary has moved well beyond card authorization. Fraud teams that still organize around a payment-first model will miss the governance gap where first-party abuse and account abuse actually accumulate. The practitioner conclusion is that lifecycle risk needs to be governed as one system, not separate channels.
A few things that frame the scale:
- U.S. fraud losses are projected to reach $40 billion by 2027.
A question worth separating out:
Q: Should ecommerce fraud teams prioritise conversion protection or tighter controls?
A: They should prioritise risk-based friction, not one over the other. Tight controls that block legitimate buyers damage revenue, but loose controls increase fraud and return abuse. The practical goal is to apply additional verification only when account trust, device reputation, or transaction behavior justify it, so legitimate customers move smoothly and high-risk activity is challenged.
