Plus de 600 avisEn bref :
- Identify the fraud pattern and actual loss before choosing a response.
- Treat risk signals as investigation inputs rather than proof.
- Separate fulfillment evidence from payment authorization and liability.
- Measure net losses alongside legitimate customer outcomes.
Ecommerce fraud is deceptive activity involving online purchases, accounts, refunds, or payment flows to obtain money, goods, or services improperly. Different fraud patterns create different losses, and not every incident results in a chargeback.
Map the Fraud Pattern to the Exposure
| Pattern | Potential Exposure | First Investigation |
|---|---|---|
| Stolen-card purchase | Unauthorized payment and fulfillment loss | Payment, authentication, and order records |
| Prise de contrôle de compte | Misuse of saved payments or account value | Login, recovery, and sensitive account changes |
| First-party misuse | Disputes over purchases the cardholder made | Transaction, complaint, fulfillment, and communications |
| Return or refund abuse | Improper credits or inventory loss | Return item, original order, and credit history |
| Triangulation | Goods received by a legitimate buyer but funded with stolen payment details | Relationship between payer, buyer, recipient, and order |
| Test de cartes | Abusive validation attempts and some successful payments | Failed and successful payment activity together |
| Promotion or stored-value abuse | Improper discounts or value transfers | Eligibility, redemption, and account history |
Stripe’s fraud documentation provides examples of stolen-card activity and related schemes. Use the pattern to guide investigation, not to assign a dispute code before reading the claim.
Distinguish a Signal From a Finding
An unusual device, address, order value, or purchase frequency can warrant review. None is universal proof of fraud. Compare the activity with customer context, the product, and normal order flow.
The Stripe fraud-identification guide describes indicators to assess. Separate the observed signal, action taken, and later confirmed outcome in your records so assumptions do not become permanent customer labels.
Use unauthorized-transaction investigation for possible compromise and card-testing incident handling for coordinated validation activity.
Understand the Limits of Fulfillment Evidence
A delivery record establishes where goods were sent; it does not automatically show that the cardholder authorized the purchase. In a hypothetical triangulation case, a genuine buyer receives an item while another person’s stolen card funded the order. Correct delivery can coexist with unauthorized payment.
An established account can also be compromised. Review changes around the transaction rather than treating account age as conclusive. Friendly fraud requires supporting facts rather than being the default explanation for a loss.
Apply Controls at the Relevant Stage
- Protect account login, recovery, and sensitive changes.
- Use supported payment authentication and risk controls.
- Review meaningful post-purchase changes before irreversible fulfillment.
- Verify original orders and prior credits when handling returns.
- Respond to filed disputes using the actual claim and relevant evidence.
The payment prevention guide explains ownership. Early dispute alerts complement these controls for eligible events, but do not replace account security or cover every fraud pattern.
Assess Liability and Recovery Separately
Authentication can affect liability for some fraud disputes under network rules. Confirm the transaction result and applicable protection. Do not infer liability from a fingerprint, address match, or wallet name alone.
For a filed case, use the reason code and representment workflow. For other losses, identify the relevant refund, account-restoration, provider-reporting, or recovery process. Promotion abuse does not necessarily have a card chargeback path.
Measure Net Loss and Customer Impact
Track confirmed fraud loss, recovered funds, product loss, service charges, refund leakage, review workload, and complaints. Avoid counting the same loss twice across revenue and cost measures.
Compare equivalent cohorts when assessing a rule. Lower fraud may reflect stronger controls, a different sales mix, or fewer legitimate approvals. Record decisions and outcomes to distinguish those explanations.
Use fraud management responsibilities to align risk, support, finance, and dispute operations. If post-purchase assessment is a gap, explore Chargeflow Prevent.
Foire aux questions
Does ecommerce fraud always become a chargeback?
Ecommerce fraud can create losses through returns, promotions, or account value without a card chargeback. The recovery path depends on the incident.
Does successful delivery disprove a fraud claim?
Successful delivery does not independently prove cardholder authorization. Investigate the payer, recipient, authentication, and transaction context.
Can device data establish liability by itself?
Device data can support risk analysis, but does not independently determine card-network liability or prove identity.
How should a fraud-control change be evaluated?
Use comparable cohorts and track confirmed losses, recoveries, legitimate approvals, customer complaints, and operating costs.
