What it is

A clear plan for your dispute response

AntiChargeback is a free checklist generator for online merchants responding to card disputes. It turns the dispute reason and the evidence you have into an organized list of what to gather, what's missing, and how to structure your response.

It doesn't file disputes for you, connect to your payment processor, or predict outcomes. It helps you put together a complete, well-organized response before the deadline.

Features

Everything you need to prepare a response

Reason-specific checklists

Fraud, not received, not as described, canceled subscriptions, credits and duplicates each need different proof. The list changes with the reason.

Card network notes

Relevant notes for Visa, Mastercard, American Express and Discover, such as Visa's Compelling Evidence 3.0 criteria for fraud disputes.

Gap detection

Flags key evidence you haven't marked as available, so you know what to dig up first.

Cover letter outline

A structured outline with a lettered exhibit list built from the evidence you actually have.

Deadline aware

Enter the response date from your processor's notice and see how many days you have left.

Private by design

Runs entirely in your browser. No account, no uploads, nothing stored on a server.

FAQ
Questions, answered

    
Is it free?
Yes. The checklist builder is free to use while it's in beta, with no account required.


Does AntiChargeback submit my dispute?
No. It helps you prepare. You still upload your evidence and submit the response through your payment processor's dispute dashboard.


Will this win my dispute?
No tool can promise that. The card issuer decides the outcome. A complete, well-organized response on time simply gives your evidence the best chance of being considered.


Is my data stored anywhere?
No. Everything runs in your browser with JavaScript. Nothing you type is sent to a server, and it's cleared when you reload the page.


Which payment processors does it work with?
It's processor-agnostic. The checklist covers the kinds of evidence card networks ask for, whatever platform you use to accept payments.


Is this legal advice?
No. It's general guidance based on common card network evidence requirements, which change over time. Your processor's instructions take precedence.
