Description

Catches duplicate and limit-bypass orders with evidence before they ship. Never blocks or cancels.

When a customer orders twice, or bypasses a one-per-customer promo using several emails at one address, Duplicate Order Defender notices as each order arrives. Flagged orders wait in a review queue with plain evidence: the matched email, address, or phone, and the time between orders. Matching sees through Gmail aliases, and related orders group into one cluster. The app tags flagged orders and, if you enable it, pauses fulfillment until you review. It never cancels or blocks checkout.
