Stoplist: Checkout Blocklist

Stoplist: Checkout Blocklist is an app designed to help ecommerce merchants prevent chargebacks and fraud by refusing checkout to blocked buyers. The app allows merchants to block buyers from placing orders, add blocked buyers manually, or automatically block buyers who have caused Shopify Payments chargebacks. Blocked buyers are prevented from checking out, including during express checkouts, and are shown a message. Stoplist ensures that emails, phone numbers, and addresses are matched regardless of how they are typed, using a one-way code for each detail.
