The Problem We Solve

Shopify is great at taking orders—but it's not built to enforce purchase limits or catch duplicates.

⏱️ Manual Busywork

Your team spends hours manually scanning orders to find matches before they hit the warehouse.

📦 Shipping Waste

If you don't catch duplicates, you pay for two labels when one would have sufficed.

🔎 Fulfillment Risk

Repeat orders from the same customer, address, phone, or SKU deserve review before your team buys labels or ships inventory.

Everything You Need to Protect Your Store

Powerful detection logic that works in the background 24/7.

Smart Order Flagging System

Duplicate Guard checks email, phone, shipping addresses, and product SKUs against your configured rules so your team can review likely duplicate orders before fulfillment.

Instant Tagging

We focus on FLAGGING. Orders are instantly tagged with Merge_Review_Candidate so your fulfillment team knows to pause and review.

Custom Rules

Set your own time windows and matching criteria. You decide what counts as a duplicate for your specific business needs.

SKU Detection

Prevent customers from circumventing sales limits by detecting when the same SKU is re-ordered within your defined time window. Perfect for limited edition items.

Suspicious Repeat-Order Review

Flag repeat-order patterns when customers place multiple orders with matching details. Review possible reseller, abuse, or mistake patterns before you ship.

Why Flagging is Better than Merging

The Risk of Merging

Competitors focus on MERGING. This is complex and risky. Automatic merging can lead to data loss, incorrect inventory counts, and customer confusion if done incorrectly.

The Safety of Flagging

We focus on IDENTIFICATION. We identify. You decide. Our Smart Order Flagging System notifies you via Email/Slack and tags the order. It's simpler, lower risk, and keeps you in full control.

Frequently Asked Questions

How does Duplicate Guard detect duplicates?
We analyze every incoming order and compare it with your recent order history based on customer email, phone number, and shipping address. If we find a match within your specified time window, we flag it.
Does it work on the free plan?
Yes! The free plan includes full duplicate detection for up to 30 duplicates per month. It's perfect for testing the app or for stores with lower volume.
What happens when an order is flagged?
We automatically add a tag (e.g., Merge_Review_Candidate) to the order in Shopify. This allows you to filter orders in your admin or set up automation flows to hold fulfillment.
Can I cancel my subscription anytime?
Absolutely. You can cancel your subscription at any time directly from the app dashboard. There are no long-term contracts.
Why can't I just use Shopify Flow for this?
Shopify Flow is powerful, but duplicate detection can get awkward when guest checkout, changed emails, address matching, or SKU-specific rules are involved. Duplicate Guard is built around configurable matching rules and review-first tagging so your team can investigate before fulfillment.
Does it work for COD (Cash-on-Delivery) stores without customer emails?
Yes! Duplicate Guard is perfect for COD and phone-first checkout flows common in markets like India. We detect duplicates using phone number + name or phone number + address matching—no email required. If your checkout only collects mobile numbers, we've got you covered.
