Chargeback Evidence by Industry: What to Submit to Win
Quick answer
Evidence requirements differ significantly by industry. eCommerce: delivery confirmation + recipient signature. SaaS: login records + terms acceptance + usage analytics. Travel: booking confirmation + no-cancellation record. Gaming: session logs + device IP match. Crypto: KYC + blockchain confirmation. Generic evidence (order receipt alone) wins rarely - industry-specific evidence wins.
The most common reason merchants lose winnable chargebacks: submitting generic evidence that doesn't address the specific claim type or industry. A SaaS company submitting an order confirmation for an unrecognized-charge dispute - without login logs showing active usage - is providing evidence that doesn't speak to the dispute. This guide shows exactly what evidence moves the needle per industry.
Evidence Requirements by Industry
eCommerce (Physical Goods)
Top disputes: Not received, not as described, unauthorized
Must-have evidence
- ✓Carrier tracking with delivery confirmation
- ✓Delivery address matching the order record
- ✓Recipient signature (for high-value items)
- ✓Order confirmation email sent to cardholder
- ✓Customer communication history
Strong optional evidence
- +AVS/CVV match confirmation
- +IP address at time of purchase
- +Prior successful deliveries to same address
Common mistake
Providing a tracking number without confirmed delivery - "in transit" is not evidence of delivery.
SaaS / Subscription
Top disputes: Unrecognized charge, non-cancellation, unauthorized
Must-have evidence
- ✓Account login records (dates, IP, user agent)
- ✓Terms of service acceptance with timestamp
- ✓Billing notification emails sent before charge
- ✓Feature usage analytics
- ✓Renewal notice email (7+ days before charge - Mastercard 2026 rule)
Strong optional evidence
- +Session recordings showing active use
- +API call logs for developer tools
- +Support ticket history
Common mistake
Submitting terms of service text without proof the customer accepted it - need the acceptance timestamp and IP.
Gaming & Digital Entertainment
Top disputes: Unauthorized in-app purchase, unrecognized charge, not as described
Must-have evidence
- ✓Session logs (login IP, device ID, game activity)
- ✓In-game purchase timestamps and item records
- ✓IP consistency with prior purchases from same account
- ✓Device fingerprint matching prior undisputed transactions
- ✓Account history showing progression post-purchase
Strong optional evidence
- +Player chat logs if relevant
- +Screenshot of in-game items received
- +Support ticket history
Common mistake
Only providing the transaction record without session data - session logs are what win gaming disputes.
Travel (Hotels, Airlines, OTAs)
Top disputes: No-show, cancellation, service not as described
Must-have evidence
- ✓Signed booking confirmation with cancellation policy
- ✓Guest check-in record (for no-show disputes)
- ✓No-cancellation record (showing no cancellation was requested)
- ✓Communication with guest pre-stay
- ✓Cancellation deadline shown in confirmation
Strong optional evidence
- +Property photos (condition disputes)
- +Staff statements for service disputes
- +Weather/force-majeure records for cancellation disputes
Common mistake
For no-show disputes: not having a signed no-show policy is almost always fatal - courts and networks expect it.
Crypto / Digital Assets
Top disputes: Unauthorized, goods not received (unfulfilled order)
Must-have evidence
- ✓KYC documentation accepted at account creation
- ✓Wallet address linked to the account
- ✓Transaction hash and blockchain confirmation
- ✓IP/device match with prior undisputed purchases
- ✓Terms of service with "no chargeback on fulfilled orders" clause
Strong optional evidence
- +Account activity since purchase
- +Binance/Coinbase equivalent order confirmation
- +AML screening pass record
Common mistake
Assuming crypto transactions can't be charged back - card-funded crypto purchases can be disputed and are won only with strong KYC evidence.
Event Ticketing
Top disputes: Canceled event, no-show, not as described
Must-have evidence
- ✓Ticket delivery confirmation (email/app)
- ✓Ticket scan record for attended events
- ✓Event occurred confirmation (for "event didn't happen" disputes)
- ✓Refund policy shown at purchase
- ✓Communication with customer re: event changes
Strong optional evidence
- +Venue check-in system data
- +Seat assignment records
- +Force-majeure documentation for rescheduled events
Common mistake
For postponed (not canceled) events: not documenting that the event was rescheduled vs. canceled - these are treated differently under dispute rules.
