If you need to prevent over-ordering of a best-seller or limited-edition item, you can enforce a per-order cap on that single product—no Shopify Plus required. Using the Nex Minimum Order Quantity app, you’ll lock down purchase quantities for just that one SKU. Here’s how, updated to include the naming step explicitly.
Why Limit Only One Product?
- Protect inventory: Stop any single shopper from clearing your limited stock.
- Maintain fairness: Ensure more customers have access to high-demand items.
- Build exclusivity: Position your product as a coveted, limited-quantity release.
Step-by-Step Setup
Step 1: Install the Nex Minimum Order Quantity App
- In Shopify admin, go to Apps → Shopify App Store.
- Search for “Nex Minimum Order Quantity”.
- Click Add app and complete installation.

Step 2: Open the Product Limit Builder
- From Shopify admin, select Apps → Nex Minimum Order Quantity.
- Click Configure under the Product Limit section.

Step 3: Create & Name Your Max-Quantity Rule
- Click Create new Product Limit.
- In the Title field at the top, enter a descriptive name (for example, “Max 2 – Limited Edition Tee”).
- Toggle Enable/Disable Limit to Enabled.

Step 4: Select “Product Max Quantity”
- In the left sidebar under Product, click Product Max Quantity.

Step 5: Configure the Maximum Quantity & Products
- In the Maximum Quantity field on the right, enter your cap (e.g., 3).
- Click Select Products, then search for and select only the specific product you want to limit.
- Click Apply (or Done) to confirm.

Step 6: (Optional) Customize the Error Message
- If you’re fine with the auto-generated message (“You can only purchase up to 3 of this item per order.”), leave Use custom message off.
- To write your own, toggle Use custom message on and enter something like: “Limit reached—max 3 per customer. Happy shopping!”

Step 7: Save Your Rule
- Click the Save button at the top.
- Your rule is now live—only that one product will be capped at your specified quantity.
