What breaks when AI can draft return claims for consumers?

What actually breaks in the fraud signal

The core break is not that return requests disappear as a control point, it is that their surface form stops telling you much. Once an AI can draft a coherent explanation, the usual human shortcuts, grammar quality, tone, detail level, apology style, and emotional framing, become easy to fake. That weakens manual review and forces teams to treat the claim as one weak input among several.

In practice, this means the signal shifts from message quality to claimant behaviour over time. A persuasive request may still be legitimate, but it no longer deserves extra trust on its own.

Merchant teams should assume the content layer is now cheap to manufacture, and the stronger indicators are elsewhere: prior return frequency, device and account history, SKU patterns, timing, fulfilment anomalies, and whether the request matches the customer’s normal behaviour.

Why AI-generated claims change the review model

AI changes the review model because it makes low-effort fraud look operationally normal. A bad actor no longer needs strong writing skills or obvious copy-paste templates to create a plausible story. That lowers the friction for scaled abuse, including serial return abuse, claim inflation, and attempts to blend genuine and false cases together.

This also creates a fairness issue for support teams. If reviewers still overweight polish, they can end up approving deceptive claims and rejecting terse but valid ones. The better approach is to separate presentation quality from trustworthiness and to score the claim against evidence that is harder to imitate.

For that reason, many organisations are moving toward rules and models that emphasise NIST Cybersecurity Framework 2.0 style governance, meaning the process is monitored as a control, not treated as a one-time policy decision. The operational question becomes whether the review process still detects abuse under changing claimant behaviour.

What merchants should score instead of prose quality

The best signals are the ones that AI has a harder time imitating at scale. That usually includes return velocity, refund history, item category risk, purchase-to-return ratio, account age, device reuse, address reuse, payment instrument patterns, and whether the return reason aligns with known fulfilment or product issues. In a returns workflow, this is closer to fraud analytics than to document reading.

Where the claim touches customer identity or account access patterns, stronger identity controls matter as a supporting layer. A platform should be able to tell whether the same person, device, or household is repeatedly surfacing suspicious requests, and whether account takeover or session abuse is contaminating the signal. Controls for authenticated customer flows and risky interactions are relevant here, including NIST SP 800-63 Digital Identity Guidelines and NIST Privacy Framework for handling trust and data use responsibly.

Where automated workflows or agents help triage claims, the risk shifts again: the organisation must ensure those systems do not blindly accept fluent text as evidence. That is why agentic review paths need controls around tool use, escalation, and human override, as reflected in OWASP Agentic AI Top 10 and NIST AI Risk Management Framework.

Risk and Threat Considerations

When AI can draft convincing return claims, the main risk is false confidence. A polished narrative can conceal abuse, inflate entitlement, or mask account compromise, and manual reviewers may over-trust communication style instead of evidence. The more a team relies on subjective tone, the easier it is for adversarial claims to blend in.

Failure mechanism: The attacker or abuser uses AI to generate believable, consistent, and emotionally persuasive return narratives, which reduces the discriminating value of the claim text and increases the chance that risky requests pass review.

Impact: Fraud losses rise, legitimate reviews slow down, and teams either over-tighten approvals or waste time on manual scrutiny that no longer improves decision quality.

Practitioner Guidance

What to prioritise: Move the review standard away from prose quality and toward corroborating evidence. If the text is persuasive but the behavioural history is poor, treat the request as higher risk rather than more credible.

What to verify: Check whether your return workflow can still identify serial abuse, repeat-device behaviour, repeated refund patterns, and mismatches between the request and the customer’s historical purchasing profile.

Practitioner takeaway: The important shift is not from manual review to automation, it is from trusting the claim itself to trusting the surrounding evidence and the control environment that evaluates it.
