Disputes resolved in seller’s favour ÷ total resolved. PayPal is buyer-friendly; below 35% means evidence packs are weak.
At a glance
The percentage of resolved buyer-protection cases that the merchant won (resolved in seller’s favour) out of all closed cases in the period. PayPal’s Buyer Protection programme is structurally buyer-friendly, which means a healthy industry baseline is 35-50 percent seller-win rate. Brands consistently below 35 percent are losing winnable cases through weak evidence submissions; brands consistently above 60 percent are either selling extremely well-described digital products, defending only the strongest cases, or have an unusually high friendly-fraud cohort. PayPal disputes follow a fundamentally different escalation path than card-network chargebacks; this card surfaces how well the merchant is navigating that path.

A UK-based fashion brand on Shopify accepting PayPal alongside card payments through Stripe, processing roughly 12 percent of order volume through PayPal. Snapshot for the rolling 90-day window ending Wednesday 15 May 26.
What the per-category view is telling us:
- The 52.2 percent blended win rate is in the healthy upper band for a fashion brand. Industry data puts the typical fashion-vertical PayPal seller win rate at 35-50 percent; 52.2 percent indicates the brand is doing meaningful evidence work. The headline figure is reassuring; the diagnostic value sits in the per-category breakdown.
- The INR cohort at 73.8 percent is close to peak performance. Item Not Received is the most defensible category because shipping carrier tracking and delivery confirmation are objective evidence. The 22 lost cases of 84 typically split: ~12 cases where the tracking shows delivery to the wrong address (carrier error, not seller fault, but PayPal still favours buyer); ~6 cases where the buyer claims the package was stolen from the doorstep after delivery; ~4 cases where tracking was missing or incomplete. The lever to push INR win rate higher is signature-required delivery for orders above a value threshold (typically £100); this adds ~£0.50/order cost but raises INR win rate by 5-10 percentage points.
- The SNAD cohort at 35.3 percent is the load-bearing problem. SNAD is buyer-friendly by design; PayPal’s bias is “if the buyer says it’s not as described, the buyer is right unless the merchant has overwhelming counter-evidence”. Brands at 35 percent are at the floor of “evidence pack is reasonable but not exceptional”. Lifting SNAD win rate to 45-50 percent typically requires: (a) photographing every item before shipping with timestamps and order-number visible; (b) documenting the product detail page at sale time as a screenshot stored against the order; (c) clear return-and-refund policy that the buyer accepted at checkout; (d) a written response to the SNAD claim that addresses the buyer’s specific complaint, not a boilerplate denial.
- The Unauthorised Transaction cohort at 9.1 percent is at the floor. This is structural; PayPal almost always rules in favour of buyers in unauthorised-transaction cases unless the merchant has enabled 3DS authentication and the transaction was 3DS-verified. For brands wanting to reduce unauthorised-transaction losses, the lever is upstream: enable 3DS on PayPal-funded orders, particularly high-value ones. This shifts liability to the issuing bank for verified transactions. The trade-off is checkout friction (3DS adds a step), so brands with high cart-abandonment risk often choose to absorb the unauthorised-transaction losses instead.

The 38 refund-request cases that closed before claim escalation are not in the calculation but represent meaningful operational signal. When a merchant proactively refunds a buyer through the Resolution Centre, no claim is filed and no win/loss is recorded. Brands with high “refund before claim” rates are doing the right thing: it preserves the customer relationship and avoids the dispute counting against the merchant’s PayPal account standing. The
pp_refund_velocitycard surfaces this proactive-refund pattern. -
Account-level implications. PayPal monitors merchant accounts on three thresholds: (1) dispute-rate (similar to card-network metrics, see
pp_dispute_rate); (2) buyer-protection-loss-rate (lost cases × disputed value ÷ payment volume); (3) chargeback-escalation rate (claims that escalate to card-network chargebacks). A 52.2 percent win rate keeps the merchant safely below the buyer-protection-loss-rate threshold for account standing; thepp_payment_health_scorecard surfaces this composite.
- Decompose by category.
pp_dispute_reason_mixbreaks resolved cases by INR, SNAD, Unauthorised. The category mix usually concentrates the problem; SNAD is the most-fixable. - Cross-reference with
pp_dispute_response_time. Cases lost because the merchant did not respond within 10 days of the dispute opening are 100 percent operational waste; the buyer’s claim auto-resolves in their favour after the response window. Brands at low win rates typically have high response-time gaps. - Check
pp_dispute_valuefor the financial impact. Win rate is a count-ratio; the currency-denominated loss surfaces here. A 30 percent win rate on a £20,000 disputed-value 90-day cohort is a £14,000 loss; a 30 percent win rate on a £200,000 cohort is a £140,000 loss. Effort allocation should match the financial size. - Pair with
pp_seller_protection_coverage_rate. Seller Protection covers specific patterns (validated tracking, no-signature-required exceptions); brands not following the Seller Protection process leave eligible coverage on the table. - For high-volume brands, consider Resolution Centre automation. PayPal’s API allows automated case-creation, evidence-uploading, and status tracking. Brands above ~50 disputes/month typically benefit from semi-automated dispute response that ensures consistent evidence packs.

Reconciling against the vendor’s own dashboard
Where to look in PayPal’s own dashboard:- PayPal Resolution Centre for the live list of open and closed disputes with full message threads and evidence trail.
- PayPal Business → Reports → Disputes Report for the case outcome breakdown over time. The Resolution Centre’s “Closed cases” tab is the closest 1-to-1 comparison to this card.
- PayPal Business → Insights → Account Health for PayPal’s own composite health score that includes win rate as one input.
Cross-connector reconciliation:
Quick rule for support tickets: if a merchant says “PayPal shows 60 percent win rate, your card shows 52 percent” in the same period, the most common cause is the refund-before-claim filter (PayPal’s default report includes them; Vortex IQ excludes them). The next-most-common is the chargeback-escalation timing. If the gap exceeds 10 percentage points and neither cause applies, check whether the merchant is comparing the same time window (PayPal defaults to 30-day windows; this card uses 90-day).
Known limitations / merchant FAQs
Why is my PayPal win rate so much lower than my Stripe chargeback win rate? PayPal’s Buyer Protection programme is structurally buyer-friendly by design (it is one of PayPal’s primary value propositions to consumers). PayPal favours buyers in close cases unless the merchant has overwhelming evidence; card-network chargebacks have more balanced dispute resolution rules with codified evidence requirements. Brands typically see PayPal win rates 10-20 percentage points below their Stripe chargeback win rates for the same product mix and operational quality. This is not a sign of weak operations; it is the structural difference between the two dispute-resolution systems. My win rate is 25 percent. Should I stop accepting PayPal? Probably not. PayPal still drives meaningful incremental revenue for most ecommerce brands (the buyer-friendly programme is partly why customers choose PayPal at checkout; they trust the safety net). The economically correct framing is net contribution:(PayPal revenue) - (PayPal-driven dispute losses) - (PayPal fees) - (operational cost of dispute defence). Brands with even a 25 percent win rate usually still see positive contribution from PayPal because the dispute losses are typically 1-3 percent of PayPal revenue, while PayPal acceptance lifts conversion rate by 5-15 percent on the orders that include it. The right response to low win rate is to fix the operational evidence-pack quality, not to drop the channel.
What evidence pack should I submit for an Item Not Received dispute?
PayPal’s Resolution Centre accepts: shipping carrier name and tracking number, delivery confirmation (PDF, screenshot, or carrier-API response), the order-confirmation email sent to the customer, and any post-purchase customer-service interactions. Best-practice pack: (1) tracking number with link to carrier confirmation page; (2) screenshot of carrier delivery scan with timestamp; (3) buyer’s IP address and account login history (if available); (4) order-confirmation email; (5) any messages from the buyer post-delivery. PayPal weights signature-required deliveries more heavily than no-signature; brands shipping high-value items should require signatures.
What evidence pack should I submit for a Significantly Not As Described dispute?
(1) Photos of the item taken before shipping with timestamp and order number visible; (2) screenshot of the product detail page at the time of sale (the description the buyer agreed to); (3) the buyer’s specific complaint quoted from the dispute message; (4) a written response addressing the specific complaint (not boilerplate); (5) the merchant’s published return-and-refund policy that the buyer accepted; (6) any post-purchase customer-service messages where the buyer’s complaint was discussed. Generic responses lose; specific, evidence-supported responses win.
Should I just refund every dispute to avoid losing PayPal account standing?
Refunding every dispute does keep account standing intact in the short term, but it has long-term consequences: (a) the merchant pays back the disputed amount in every case, including ones that were friendly fraud and would have been won; (b) PayPal’s algorithm tracks “merchant always refunds” patterns and may classify the merchant as high-risk, raising rolling reserves and tightening payout schedules; (c) the customer learns “filing a dispute always works” and the dispute rate climbs over time. The economically right response is to defend cases the merchant believes are recoverable (typically 30-60 percent of disputes) and pre-emptively refund the rest before they escalate.
Why are my Unauthorised Transaction win rates so low?
PayPal’s policy strongly favours the cardholder in unauthorised-transaction cases unless the merchant has 3DS authentication on the original transaction. Without 3DS, the merchant typically loses regardless of evidence quality. The lever to raise unauthorised-transaction win rates is upstream: enable 3DS for PayPal-funded orders, particularly above a value threshold. The trade-off is checkout friction (3DS adds a step), so brands choose whether to absorb the unauthorised-transaction losses or to add the friction. The pp_threedsecure_abandon_rate card surfaces the friction cost.
Can I appeal a lost case?
Yes, within 10 days of the case closing. Appeals require new evidence (not a re-submission of the original pack). Successful appeals typically include: shipping carrier delivery-confirmation that arrived after the case closed, a buyer follow-up message admitting the item was received, or new customer-service messages clarifying the dispute. Appeals win in roughly 20-30 percent of cases when accompanied by genuinely new evidence; appeals based on the same evidence almost always fail.
My win rate suddenly dropped 15 percentage points this month. What happened?
Common causes, in order of likelihood. (1) Operational team change: a customer-service team turnover, holiday cover, or process change can degrade evidence-pack quality. The first 30 days post-team-change usually show degradation. (2) PayPal policy update: PayPal updates Buyer Protection policy quarterly; the most recent updates have generally tightened seller win rates in SNAD cases. (3) Product-category shift: a new product launch in a category with higher SNAD risk (apparel, jewellery, electronics) raises overall dispute volume and reduces the blended win rate. (4) Geographic expansion: launching in new markets brings unfamiliar dispute patterns; localising the evidence-pack response (translation, region-specific carrier evidence) takes time. (5) Genuine fraud-pattern shift, less common but possible.
Can Vortex IQ submit dispute evidence on my behalf?
Read-only by design. Vortex IQ surfaces win-rate patterns, identifies process gaps, and flags low-win-rate categories for operational attention; the merchant’s customer-service team executes inside PayPal Resolution Centre. The Vortex Mind Decline Recovery Intelligence report generates merchant-side Actions when win-rate degradation patterns suggest specific fixes (e.g. “INR win rate dropped because tracking number quality degraded”), but the response itself sits with the merchant.
Is win rate the only metric that matters for PayPal account standing?
No. PayPal’s account-health score combines win rate, dispute rate, dispute-value-to-payment-value ratio, chargeback rate, and seller-protection-coverage compliance. The composite pp_payment_health_score card folds these into one number. Brands focused only on win rate without watching dispute rate can still hit account-standing thresholds even with healthy win rates if dispute volume scales aggressively.
