01

Checkout level action

When a rule matches a risky buyer, the goal is to stop the order before payment instead of cleaning up the damage later.

02

Signals merchants already know

Use customer details such as email, phone, name, address, country, and IP when the risk pattern is clear.

03

Rules with reasons

A block list should be reviewable. Keep a short reason for fraud, chargeback, return abuse, spam order, or store policy risk.

04

Careful location rules

Country and IP rules should be tied to shipping limits, compliance, or confirmed fraud patterns, not discriminatory targeting.

05

Policy-ready guidance

The workflow helps store teams move from a messy support note to a clear rule, test, and review process.

FAQ

Common questions from Shopify merchants.

Short answers about customer blocking, checkout rules, and repeat risk control.

Where does the install button go?

It sends merchants to the Block Customer & Stop Returns listing on the Shopify App Store.

Should I start with a broad country rule?

No. Start with the most specific buyer signal you can verify, then use country or IP rules only when the business reason is clear.

Can this replace normal fraud review?

No. Use it as a blocking layer for known repeat risk while keeping normal fraud review for new or unclear orders.

Can country blocking copy create risk?

Yes. Country rules should be framed around shipping, compliance, and confirmed fraud patterns, not nationality or protected groups.
