Service Disputes Now Outpace Fraud: Merchant Playbook

The short answer: Service disputes are now the growth story in chargebacks: Product Not Received and Cancelled Recurring claims rose from 13.0% to 24.1% of contested chargebacks in a year, while fraud fell from 74.6% to 60.4%. For merchants, the winning evidence is no longer just fraud screening — it is proof of delivery and proof of cancellation, kept case by case.

The shift: service up, fraud down

Justt's The Fraud to Service Shuffle: The 2026 Chargeback Benchmark Report, announced October 27, 2026, is built on contested chargebacks processed through Justt's platform from July 2024 to June 2026, checked against a fixed cohort of 165 merchants across seven industries worldwide. That scope matters for how far the numbers travel: this is Justt-processed volume, not a census of every chargeback on every network. Within that sample, the headline is stark. Product Not Received and Cancelled Recurring claims together rose from 13.0% to 24.1% of contested chargebacks in a year, while fraud's share fell from 74.6% to 60.4%, described in the release as a two-year low. The report's framing, in CEO Ofir Tahor's words quoted in the release, is that cardholders increasingly treat disputes as a customer service channel: why chase a merchant about a late package when a call to the bank can claw the money back?

Volume is still rising underneath the mix change. The median merchant in the sample handled 13% more contested chargebacks year over year, and one in four saw volumes jump 68% or more. The release also cites a forecast of more than 281 million card chargebacks in 2026, attributed to Datos Insights and Mastercard. Treat that forecast as a third-party projection reported in a vendor release, not as a counted total.

The new evidence discipline

The practical consequence is a change of evidence, not just of mood. A fraud defence leans on identity signals: device, IP, authentication, prior history. A service defence leans on fulfilment and communication records. For a Product Not Received claim, the decisive packet is tracking to the cardholder's address, delivery confirmation, and any delivery photo or signature the carrier captured, plus the order confirmation the customer actually received. For a Cancelled Recurring claim, it is the cancellation record itself: when the customer cancelled, what confirmation was sent, whether billing stopped on the date promised, and what the customer was told at sign-up about the billing cycle. A merchant that can produce those two packets quickly wins service cases; a merchant that stores only payment data loses them, however good its fraud screening is.

Two habits make the difference. First, send the proof before it is asked for: a delivery confirmation email at the moment of delivery, and a cancellation confirmation email at the moment of cancellation, each stating the order or subscription, the date, and what happens next. Second, keep those confirmations retrievable by order number, not buried in a support inbox. When a dispute arrives weeks later, the merchant that searches one order number and finds both the tracking event and the confirmation email answers in minutes; the merchant that reconstructs the story from chat logs answers late, or not at all.

Why win rates vary so much

The report's second warning is about partners, not customers. For the same claim type and quarter, win rates for fraud-coded chargebacks varied by more than 30 points between payment processors and by more than 35 points between major US card issuers, and merchants won fraud disputes roughly twice as often on one of the two largest card networks as on the other. The release does not name the processors, issuers or networks behind those gaps, so no merchant should read this as a ranking to switch on. The usable lesson is narrower and still valuable: dispute outcomes are not a pure measure of how right you were. Processor evidence-submission quality, issuer handling and network rules all move the result. If your win rate is far below peers on the same claim type, ask your processor what evidence it actually submitted, in what format, and whether anything was truncated or missing — before concluding the claims themselves are unwinnable. The UK and Ireland are the one regional exception in the release: the only major region where service disputes already outnumber fraud, which the release links to Strong Customer Authentication shifting fraud liability to card issuers. Merchants selling into the UK and Ireland should expect service evidence to matter even more there.

The 2026 playbook: four habits

Prove delivery, in the customer's inbox, on the day. Tracking links, delivery confirmation and a plain-language order summary, sent automatically, head off the “never arrived” call to the bank.
Confirm every cancellation in writing, immediately. Date, final billing date, and a reference the customer can quote. Most Cancelled Recurring disputes are really “I thought I cancelled” disputes; a confirmation email ends that argument.
Make support easier than the bank. A visible refund and cancellation path, answered fast, converts a would-be dispute into a resolved complaint. Every dispute that starts at your help desk instead of at the issuer is one you never have to fight.
Audit your representments by claim type and partner. Track win rates separately for Product Not Received, Cancelled Recurring and fraud, and separately by processor where you use more than one. A gap of the size Justt reports is a signal to investigate submission quality, not to accept the loss rate.

Watch item: ChargebackX, Nov 9–10

The release notes that the report's major findings will be presented at the free, virtual ChargebackX conference on November 9–10, 2026. That is a watch item only: we have not attended it, and nothing in this article depends on what may be said there. If the full report's detail changes any figure above, this page will be updated and the change dated.

FAQ

Are service disputes really bigger than fraud now?

Not in absolute share: fraud is still 60.4% of contested chargebacks in Justt's sample, against 24.1% for the two service categories combined. The shift is in growth — service claims nearly doubled in a year while fraud's share fell to a two-year low.

Does this mean fraud screening no longer matters?

No. Fraud remains the majority of contested chargebacks, and screening still prevents the cases that never become disputes. The change is that fraud screening alone no longer covers the fastest-growing dispute types.

Can I use these figures for my own business?

Only as a benchmark, not a prediction. The figures describe chargebacks processed through Justt's platform, checked against a 165-merchant cohort. Your mix depends on your products, fulfilment and cancellation process.
