Duplicate Guard

Spot repeated email, phone, address, and SKU signals before fulfillment, then review the order.

Duplicate Guard helps Shopify merchants review duplicate-looking orders before fulfillment. It checks recent orders for repeated email, phone, address, and SKU signals, then flags matches so your team can decide what to do next. Use it as a review layer for accidental repeat checkouts, one-per-household campaigns, limited drops, COD or phone-first orders, and other workflows where shipping the wrong duplicate can be expensive.

• Catch repeated email, phone, address, and SKU signals before fulfillment
• Review duplicate-looking orders without risky automatic merging
• Useful for COD, phone-first, free-sample, flash-sale, and limited-drop workflows
