Every year, UK ecommerce merchants lose millions of pounds not because their disputes are unwinnable — but because they don't know how to present their case.
Banks don't reward the merchant who's right. They reward the merchant who submits the strongest, most structured evidence. This guide breaks down exactly what that looks like.
Why Most Merchants Lose Chargebacks
The most common mistake is submitting raw evidence without a rebuttal letter. Screenshots, order confirmations, and tracking numbers alone won't win your case. Banks need a narrative — a clear, structured argument that connects your evidence to the specific dispute reason code.
Without that narrative, even the best evidence gets ignored.
The Evidence Framework That Works
A winning chargeback submission has four components:
- A custom rebuttal letter — written to directly counter your specific reason code (e.g. "item not received", "unauthorised transaction", "not as described")
- Proof of delivery or access — tracking confirmation, digital access logs, IP address records, or download timestamps
- Customer communication history — emails, chat logs, or any record showing the customer acknowledged receipt or made contact
- Your store policy — a clear, visible refund or no-refund policy that was present at the time of purchase
Reason Codes Matter
Every chargeback comes with a reason code — a number assigned by the card network (Visa, Mastercard, Amex) that defines the nature of the dispute. Your evidence strategy must be tailored to that specific code.
For example, a "13.1 — Merchandise/Services Not Received" dispute requires different evidence than a "10.4 — Other Fraud — Card Absent Environment" dispute. Submitting the wrong evidence for the wrong code is one of the fastest ways to lose a winnable case.
Digital Products: A Special Case
If you sell digital goods — downloads, subscriptions, or service packages — your evidence strategy is different. You can't provide a tracking number. Instead, you need:
- Server-side access logs showing the file was downloaded
- IP address confirmation matching the customer's location
- Timestamp of delivery relative to the order
- Any login or account activity post-purchase
This is exactly the type of case where most merchants give up — and exactly where a well-structured submission wins.
The Bottom Line
Chargebacks are not automatic losses. With the right framework, the right evidence, and a clear rebuttal letter, the majority of disputes are winnable.
