Flag the customers who damage, return late, or never come back. Catch them even when they change their details.

Set it up once. Then every order is checked automatically going forward.
Record anyone who has caused damage, returned late, charged back, or stolen from you. Add them by name, email, phone, or address. Any combination works.
When a matching order arrives, a clear risk flag appears on the order with the reason, severity, and incident history.
Orders are never blocked automatically. Staff see the recommended action (require ID, take a deposit, or decline) and decide for themselves.
A clear risk flag inside the order, or a green all-clear. Your staff see it exactly where they work.



If you lend it out and expect it back, this is for you.
Changed their name or email but reused a phone number or address? They are still flagged. Matching works on every field independently.
A colour-coded panel appears right inside the order: Watch, Warn, or Do Not Fulfil, with the full reason and history.
Log damage, late returns, stolen goods and notes against each person, so staff see the whole story at a glance.
Get notified by email the moment a flagged customer places an order, even when you are away from the admin.
Already keep a list in a spreadsheet? Import it as a CSV and you are protected from day one.
Read-only and isolated from your store. It cannot break your storefront, checkout, or other apps. Uninstalling leaves everything as it was.
Hire and rental businesses protecting their orders every day.
Since owning a dress hire business, I have been looking for years for an app like this, and I am so glad something like it finally exists. It is a game changer for hire businesses. One of the biggest challenges we face is customers returning items late and then continuing to place new bookings without any visibility of their previous behaviour. This app allows us to identify those customers and make more informed decisions, whether that is declining future bookings or requiring an additional security deposit. I would highly recommend it to any hire business or other like-minded businesses looking for a way to flag and manage difficult customers more effectively.

No. It never blocks, holds, cancels, edits, or fulfils orders. It does not touch your theme or checkout, so it cannot affect what shoppers see or their ability to buy. Orders flow exactly as before.
No. Shopify apps run independently and one cannot modify or break another. Blacklist Customer does not create orders, so it will not change your order sources or interfere with your booking or rental engine. It simply adds a risk-check panel to the order page.
Never. Your team always decides. The app surfaces who is flagged, why, and a recommended action. The call is always yours.
Your store is left exactly as it was. Uninstalling removes the app's access and its data. It does not alter your orders, products, customers, or other apps.
It checks name, email, phone, and address independently. So a customer who changes their name but reuses a phone number or delivery address is still flagged.
