TL;DR: First-party fraud now includes item-not-received claims, chargeback abuse, wardrobing, and promo abuse, and Signifyd says it rose 8% in H1 2025 while one in five consumers admit to it, highlighting how hard it is to distinguish fraud from legitimate disputes. The governance challenge is not only detection accuracy but preserving customer experience while proving intent at scale.
Editorial analysis by NHI Mgmt Group, based on content published by Signifyd: “What is first-party fraud detection and how to combat abuse”.
By the numbers:
- first-party fraud was up by 8% in the first half of 2025 compared to 2024
Key questions
Q: Why do first-party fraud controls fail when the customer identity is genuine?
A: They fail because the identity is real, so simple credential or payment checks do not reveal intent.
Q: How should merchants distinguish accidental chargebacks from deliberate abuse?
A: By combining customer-service signals, statement descriptors, return history, and behavioural patterns rather than treating every dispute as malicious.
Q: What are the signs that first-party fraud detection is too blunt?
A: Common signs include rising false declines, repeat complaints about legitimate orders, low dispute win rates, and heavy manual review with limited improvement in loss rates.
Practitioner guidance
- Strengthen identity-intent correlation Join checkout, dispute, return, device, and account signals so analysts can evaluate behaviour across the full buying journey rather than a single transaction.
- Reduce reliance on merchant-only review Use networked evidence and cross-merchant context to spot repeated abuse patterns that internal logs alone cannot show.
- Separate accidental from deliberate abuse Review statement descriptors, chargeback workflows, and customer-support signals so confused customers are not treated as malicious actors.
Bottom line: First-party fraud blends legitimate identity with abusive intent, which makes it harder to catch than traditional payment fraud.

First-party fraud is an identity governance problem disguised as a disputes problem. The article shows that the central control failure is not simple payment validation, but the inability to separate legitimate identity from malicious intent after a real customer has already been authenticated by the commerce stack. That makes the identity evidence set broader than checkout data and closer to lifecycle behaviour, return behaviour, and network context. Practitioners should treat dispute governance as part of identity risk management, not only fraud operations.
A few things that frame the scale:
- Nearly 60% of companies reported that fraud losses were still increasing in 2025.
A question worth separating out:
Q: How should fraud teams balance chargeback prevention with customer experience?
A: By making precision a governance goal, not only a model metric. Teams should validate dispute rules against customer friction, monitor repeat-purchase impact, and use real-time evidence to intervene only where the risk is clear. The best programmes stop abusive behaviour without turning routine disputes into a service failure.
