The Problem
Small e-commerce sellers on Shopify and Etsy lose chargebacks at an alarming rate — even when they have airtight evidence.
A thread on r/shopify with 74 upvotes captured the absurdity: a seller lost an $89 dispute on a custom embroidered hoodie with the customer's own name on it, shipped and delivered to her address. The bank sided with the customer anyway.
This isn't an edge case. It's the default.
The average chargeback win rate for small sellers is around 20%. With properly structured evidence and a professional dispute response, that number climbs above 60%. The difference isn't evidence — it's formatting. Banks respond to documentation that looks like it was written by someone who knows the rules, not a frustrated seller typing in a text box.
Most small sellers don't have time to learn bank dispute protocols. They lose not because they're wrong, but because they don't know how to fight.

The Insight
The dispute process is a writing problem, not an evidence problem.
Sellers typically have everything they need: order confirmation, shipping tracking, delivery proof, customer communications history, product photos. What they lack is the ability to assemble that evidence into a bank-ready document that follows the correct structure for the dispute reason code.
Banks process thousands of disputes. They pattern-match. A dispute response that reads like a template from a professional — with clear sections, proper citation of evidence, and language that maps to the chargeback reason code — gets more attention than a paragraph from an upset seller.
Claude knows how to write these letters. The seller knows their order. Combining both is the product.
What We Built
Chargeback Shield generates professional, bank-ready dispute letters using AI — in minutes, not hours.
The demo (try it immediately, no sign-up):
The demo is pre-loaded with the Reddit hoodie case — a real chargeback scenario where the seller had clear evidence but still lost. Walk through how Chargeback Shield would have assembled the dispute response.
The core flow:
- Enter chargeback details: customer name, item description, order amount, shipping info, reason code, and customer communications history
- Chargeback Shield pulls the evidence together and generates a structured dispute letter
- Review and edit the letter before submitting to your bank
- Copy and submit — the letter is formatted for bank review from the start

Product Decisions
Demo with a real case. The hoodie Reddit story is the product's best pitch. A custom item with the customer's name on it — delivered, confirmed — and the seller still lost. Anyone who has run an online store immediately understands this scenario. Using it as the demo makes the product immediately credible.
No sign-up wall. The demo runs without an account. You can generate a real dispute letter for your actual chargeback before creating an account or paying anything. The product has to prove itself before asking for commitment.
Reason code awareness. Different chargeback reason codes require different evidence framing. "Item Not Received" needs proof of delivery. "Item Not as Described" needs product documentation. The letter generator takes the reason code into account when structuring the response.
Seller-readable output. The generated letter is written to be understood by the seller, not just the bank. If you're going to submit it, you should be able to read it and confirm it accurately represents your case.
Manual submission for MVP. The letter generates; you submit it. Integrating directly with bank portals or Shopify's dispute flow is a v2 feature. For a prototype, the value is the letter itself.

What's Next
The letter quality is the core value proposition, and that's already working. The path to a real product from here:
- Evidence auto-pull: Connect to Shopify/Etsy OAuth to auto-populate order data, tracking, and customer message history — no manual entry
- Bank-specific formatting: Different card networks (Visa, Mastercard, Amex) have different evidence requirements; format automatically for the correct network
- Win rate tracking: Did you win or lose? Feed outcomes back to improve the letter generator over time
- Reason code library: Full documentation of every chargeback reason code with what evidence to include, so sellers understand what they're dealing with
- Volume tier: Sellers with high dispute volume could process batches; this is where the unit economics get interesting
The supply-side constraint here isn't technical — it's distribution. Small sellers don't go looking for dispute help until they lose one that stings. The acquisition moment is the loss event, not before it.
