A free, no-fluff field guide to liability-shift eligibility — how to tell, in five minutes, which Shopify disputes you can win under Visa CE 3.0 and Mastercard First-Party Trust, and exactly how to win them.
Most merchants attach a tracking number and hope. This guide gives you the structured test that decides whether a dispute is winnable before you spend an hour on it.
The five-minute, five-gate check you run on every dispute to know if it's winnable — and how.
The priors, the 120–365 day window, and the IP-or-device anchor rule that quietly sinks "obvious" cases.
The three evidence categories — Device, Delivery, Identity — that win even brand-new-customer disputes.
The signals you must log at checkout today, or you disqualify tomorrow's winnable disputes.
“Fightable means you're allowed to respond. Eligible means the network's own rules force the issuer to eat the loss. Almost no one checks the difference first.”
Written for Shopify merchants fighting 15–60 disputes a month — not for lawyers.
Specific, current rules. Includes the 2025–26 Visa 3DS auto-qualify shortcut and its fee.
Honest about the limits. The issuer always decides — this shows you how to put the odds where they belong.
