WHY THE MATH MATTERS
Winning is not the same as profiting.
Probability
Use your own historical win rate by reason code. A guess is shown as a guess, never a promise.
Labor
Evidence collection has a real hourly cost. Low-value disputes can be negative even when winnable.
Clarity
A short chronological pack is easier to review than a screenshot dump. Relevance beats volume.
PUBLIC EVIDENCE + COUNTEREVIDENCE
Built around actual rules, not “AI wins disputes.”
Official documentation shapes the checklist. Merchant reports establish the time pain. Counterevidence stays visible: automation cannot control issuer decisions.

DisputePack ROI used to sell its own Pro and Team tiers. They were removed: they sold the same job CaseRail sells. One workflow, one price.
ONE CASE. ONE DECISION. ONE PACK.

Is this free?这是免费的吗？
Yes, entirely. There is nothing to buy on this page. The paid step in the workflow is CaseRail, at $19 for one exportable case pack.完全免费，本页没有任何要卖的东西。这条工作流里要付费的一步是 CaseRail，$19 换一份可导出的案件包。
How is the ROI calculated?ROI 是怎么算的？
From your own numbers: disputed amount, chargeback fee, win rate for that reason code and the time the representment takes you. The arithmetic is shown, not hidden.用你自己的数字：争议金额、拒付手续费、该理由代码的胜率，以及你做一次申诉要花的时间。算式是摊开给你看的，不藏。
Why is this separate from CaseRail?为什么和 CaseRail 分开？
They are two steps of one job. This decides whether to fight; CaseRail builds the evidence for the ones you decide to fight.它们是同一件事的两步。这一步决定要不要打；CaseRail 负责为决定要打的那些构建证据。
