Shopify already covers some of this at no cost, though more narrowly than the name suggests. Its chargeback protection applies to fraudulent and unrecognised disputes on orders paid through Shop Pay, for merchants based in the United States, on physical goods, and only where the order was fulfilled with valid tracking inside a tight window. Where it does apply, the disputed amount and the fee come back as a credit and you take no action at all.

Everything outside those conditions is yours. A different checkout, a different country, a digital product, a slow fulfilment, or a dispute raised for any reason other than fraud, and the money is genuinely at risk. Shopify does not decide the outcome either: the customer's bank does, on the evidence you submit, and that decision is final. This is the gap the category sells into, and it divides in two, between screening orders before you ship and assembling dispute evidence afterwards.

What to look for in a Blocky app

Work out what is actually uncovered: Your real exposure depends on how your orders are paid for, where you are based, and whether you ship physical things. Some stores discover most of their volume already qualifies for free protection and the remaining risk does not justify a subscription. Others find almost none of it does. Establish which you are first.
Screening and dispute response are different products: One decides whether to let an order through before you spend money on it; the other fights the bank after the money is gone. Apps here lean heavily one way or the other despite similar listings, and buying the wrong half is easy.
A false positive is a real cost too: A rule that cancels risky orders will cancel good ones, and nobody sends you an invoice for the customer you turned away. Ask what tuning looks like, what the app shows you about orders it blocked, and how quickly a wrong call can be undone.
The clock is short: A dispute response window is measured in days, while the bank's review can run for weeks afterwards. If nobody at your end is watching for these, an app that gathers the evidence automatically is worth more than one with better scoring.

What does the Built for Shopify badge mean?

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
