Introducing Prevent 2.0: Stop Fraud and Abuse Before It Ships

Today we're releasing Prevent 2.0, a new AI model that screens every order for fraud and abuse before it ships. Prevent 2.0 is a true breakthrough in fraud protection, catching 10x more fraud and abuse than the previous generation, at a fraction of the price.

We built Chargeflow with the vision that when merchants deliver, the revenue they've earned should stay theirs. Friendly fraud has made that harder. Most disputes don't claim fraud at all. The buyer says it never arrived, wasn't as described, or that they didn't mean to renew. Prevent 2.0 screens for those too. And because it works after checkout, it never gets in the way of conversion.

What's new in Prevent 2.0

• A new AI model. Every decision now comes from the new model, after checkout and before the order ships. Nothing changes at checkout.
• Stolen cards, now covered. Third-party fraud is screened in the same decision as friendly fraud.
• Suspicious delivery patterns. Prevent now spots irregularities like different names shipping to the same address.
• Sharper on abuse. It's better at spotting friendly fraud, such as detecting buyers with a history of disputing orders they received, even on their first order with you.
• A fraction of the cost. The new, more efficient Prevent 2.0 AI model now costs only $0.10 per scanned transaction (each order or subscription renewal it screens).

See what one merchant cannot, and prevent it

Behind every decision is Chargeflow Network Intelligence, and no single store can see what it sees.

Here's what that looks like on two real orders, one good and one not. Both are anonymized.

Already running Shopify's fraud analysis? Leave it on, it's a strong initial layer. Prevent adds a powerful additional layer of protection.

Where Prevent started

Our first model, Prevent 1.0, focused on friendly fraud. Merchants who activated Prevent saw 20% fewer chargebacks in their first three months, on top of the other fraud tools they ran in parallel. Prevent 2.0 goes even further. When we tested it on past orders, it caught over 5x more “never arrived”, “not as described” and unwanted-renewal disputes than traditional fraud tools.

Disponibilité

• New to Chargeflow? Install it from the Shopify App Store in one click, then activate Prevent.
• Already use Chargeflow? Just activate Prevent.
• Already on Prevent? You're already running Prevent 2.0, at the new price. There's nothing to do.

If you're new to Prevent, your first 1,000 scanned transactions are free, through December 31, 2026. After that, Prevent is $0.10 per scanned transaction, the same price for new and existing Prevent merchants.

From your next order, Prevent screens every order and tells you what it flags, with the reasons.

Disputes on orders shipped before you switch Prevent on will keep arriving for weeks, so judge Prevent on the orders it screened. For disputes on those earlier orders, Chargeflow Automation is already in your account. It's our industry-leading AI for chargeback recovery, with $200M+ in disputed revenue recovered for merchants. No upfront cost. You pay only when Chargeflow wins. You don't have to use it. It's already there.

What comes next

We believe every merchant should have this protection, and that it should come switched on rather than as a project. Prevent 2.0 is how we deliver on that for Black Friday 2026. Switch it on before November 27, and keep more of what you've earned.
