600+ reviewsPost-purchase fraud — disputes filed after delivery or access is confirmed, is the fastest-growing chargeback category in 2026. It shows up as refund abuse, false non-delivery claims, and repeat friendly fraud. Track behavior after fulfillment, capture delivery and usage proof, and block repeat abusers early.
What is post-purchase fraud?
Post-purchase fraud is any dispute a customer files after a legitimate transaction is completed, typically after delivery or access is confirmed. Instead of contacting support, the buyer goes to their bank claiming non-delivery, an unauthorized charge, or a refund issue. It is a form of first-party (“friendly”) fraud, and it is growing because many merchants stop monitoring a customer once the order ships.
Why is post-purchase fraud rising in 2026?
Issuers are increasingly automating dispute decisions based on customer behavior and speed, and fraudsters exploit the gap after fulfillment. The numbers back the trend: Juniper Research projects friendly fraud will account for roughly 22% of all chargebacks in 2026, with losses near $8.1 billion globally, while Chargebacks911 attributes a majority of disputes to first-party misuse. Chargeflow's own State of Chargebacks Report shows disputes increasingly originating after fulfillment rather than at checkout. For the AI angle, see guarding against the fraud spike in 2026, and note that refund abuse is a core vector — the same behavior behind disputes customers file after a refund.
How do you stop post-purchase fraud?
- Tighten refund rules and timing. Make refund windows, conditions, and processing timelines clear and consistent.
- Monitor customer behavior after fulfillment. Look for patterns like disputes filed after confirmed delivery or refunds.
- Capture proof automatically. Store tracking data, delivery confirmation, timestamps, IPs, and access logs without manual effort.
- Block repeat abusers early. Chargeflow Prevent helps stop customers who repeatedly dispute after receiving or using products.
- Act before disputes escalate. Chargeflow Alerts surfaces early signals so you can respond before a chargeback is filed.

How Do I Track Dispute Performance Across Multiple Accounts?
To track dispute performance across multiple accounts, consolidate chargeback data from every processor, store, and merchant account into one dashboard, then compare the same core metrics, dispute rate, win rate, recovery rate, and reason-code trends at both account and portfolio level. Centralized reporting surfaces rising-risk accounts before they trip card-network thresholds like Visa’s VAMP.
How Do I Standardize Evidence Across Dispute Types?
Standardize chargeback evidence by building one core evidence package for every order, transaction, fulfillment, customer, and policy records, then layering in dispute-specific proof mapped to the reason code. A single repeatable framework beats managing evidence reason code by reason code: it closes gaps, speeds responses, and lifts win rates.
How Do I Align Customer Support and Payments to Reduce Disputes?
Many chargebacks start as unresolved support issues, not payment problems. When customer support and payments share one dispute-prevention queue, escalation rules, and pre-chargeback alert data, you resolve refund, delivery, and billing complaints before they reach the issuing bank.
