Chargeback Evidence by Industry: What You Need to Win

Retail and E-Commerce Evidence

For online retail, the most common dispute types are "item not received," "item not as described," and "unauthorized transaction." Each requires specific evidence.

For item not received: carrier tracking with delivery confirmation to the cardholder's address is essential. For Visa disputes, ensure the tracking shows the carrier delivered to the specific address, not just the general area. For high-value orders, signature confirmation is the gold standard — it removes almost all ambiguity. Include the order confirmation email sent to the cardholder, your shipping policy, and any customer communication post-delivery.

For item not as described: your product listing from the purchase date (not the current listing — capture the listing as it appeared at sale time), photos of the actual item shipped, your condition disclosure (particularly important for secondhand goods), and your return policy. If the cardholder had the item for an extended period before disputing, include the purchase date and the dispute date — this "delay" is relevant evidence.

For unauthorized transactions: the full transaction record showing IP address, device type, billing address match, and any additional verification steps completed at checkout. If you use 3D Secure authentication, include the authentication record — this alone often reverses fraud disputes.

SaaS and Subscription Business Evidence

Subscription chargebacks are among the most disputed and most winnable dispute types for merchants who have proper documentation systems in place. The key is proving the cardholder agreed to recurring billing and had the opportunity to cancel.

For recurring billing disputes: the original subscription signup record showing the cardholder's email, the date of signup, and the recurring billing terms they accepted. Ideally, this includes a checkbox confirmation that the customer explicitly agreed to recurring charges. Subscription renewal notification emails sent before each charge are powerful evidence — they show you gave the cardholder advance notice.

For "service not received" disputes in SaaS: login activity records showing the cardholder accessed your platform after the disputed charge, feature usage logs, support tickets or emails from the cardholder during the subscription period, and any usage reports. A cardholder who logs in 15 times after a charge and then disputes the charge as "service not received" has a very weak claim.

For cancellation disputes: the cardholder's cancellation request (if any), your response to that request, and the effective date of cancellation. If the dispute is for a charge that occurred after a cancellation request that you failed to process, issue a refund — this is not a case to contest.

Hospitality and Travel Evidence

Hotels, airlines, and travel companies face specific dispute types that require industry-specific documentation.

For hotel no-show disputes: your reservation record (name, card number, dates, room type), your cancellation policy as communicated at booking and confirmation, any documentation that the room was held and available, and any pre-arrival communication with the guest. If the guest contacted you about the reservation and you have those records, include them.

For cancellation policy disputes: the cancellation policy that was in effect at the time of booking, proof that the policy was communicated (typically the booking confirmation email that includes the policy), and the timeline of events (booking date, cancellation deadline, actual cancellation request date). If the cancellation was made after the policy deadline, document the exact timeline.

For airline disputes: the ticket purchase record, your terms of carriage, any flight change or cancellation communications, and documentation of refund procedures followed. For non-refundable tickets, the specific terms the cardholder agreed to at purchase are essential.

Digital Goods and Services Evidence

Digital products and services present unique evidence challenges because there is no physical delivery confirmation. Courts and card networks have developed standards for what constitutes adequate proof of digital delivery.

For downloadable products: server logs showing the download request and completion from the cardholder's IP address and device, the download confirmation email sent to the cardholder, and any license key or activation record. If the cardholder activated the product, include the activation timestamp.

For streaming or access-based services: login records showing the cardholder's account activity after the disputed charge, IP address data confirming logins, and any content consumption logs. Support tickets or customer service contacts during the subscription period are also useful.

For online gaming or virtual goods: transaction records for in-game purchases, any chat logs or account activity showing the cardholder used the purchased items, and your terms of service regarding virtual goods being non-refundable. Note that card networks have specific rules about disputes on virtual goods, and some reason codes do not apply.

For all digital products: your terms of service regarding refund policies and the method by which the cardholder agreed to those terms at purchase.

Service Businesses and Professional Services Evidence

Service businesses — contractors, consultants, agencies, and similar — often face "services not rendered" disputes when clients dispute charges after service delivery, particularly in cases of dissatisfaction rather than genuine non-delivery.

The essential evidence for service businesses: signed service agreement or work order with scope and price, communications from the client during the project (showing they were engaged and aware of the service being delivered), work completion evidence (photos, reports, deliverables submitted), and client acknowledgment of completion (invoice acknowledgment, acceptance email, or sign-off document).

Before-and-after documentation is powerful for trades and home services. For consulting and professional services, dated project deliverables, meeting notes, and email chains showing project progress are your primary evidence.

Crucially: a client's dissatisfaction with service quality is generally not a valid basis for a chargeback if the agreed scope was delivered. "Services not rendered" requires proving the services didn't occur at all — quality disputes are contract disputes, not chargeback disputes. If a client disputes on quality grounds, document what you delivered and why it matches the agreed scope.
