About
A chargeback notice arrives with a code on it, a deadline, and no explanation of what that code accepts as evidence. Most sellers answer it with a paragraph of frustration and a screenshot. The reviewer needs a specific list of facts, in a specific order, and cannot go looking for what is not there.
Disputekit asks you only what your reason code accepts, and then arranges your own answers into the document a reviewer can read. 49 codes across Visa, Mastercard, Amex and PayPal, with the rules traceable to the networks' own documentation and checked 2026-09.
It takes about 10 minutes. You see what you have and what is missing before you pay anything, and the pack says plainly what you do not hold rather than filling the gap with language.
Who built it
Martin Lubula, compliance consultant. The rules on this site are compiled from the card networks' published dispute documentation, PayPal's Seller Protection terms and Stripe's evidence documentation, checked September 2026, not from opinion or from our own disputes.
What it will not do
- It will not invent a fact. Every line comes from something you typed. Missing items are listed as missing, in the pack itself.
- It will not quote a win rate. Nobody can honestly predict a card network's decision on your case, and a number would only be there to sell you something.
- It will not take your money on a lost cause. When your answers show the dispute is not defensible, the review screen says to accept it and no payment is offered.
- It will not submit for you. You paste the text and attach your files in your own processor, because that is the only place the submission is real.
- It will not take your files. We never receive your attachments. The pack names each file and the order to attach it in; you attach them yourself inside your own processor.
