When a Shopify store sells limited-stock, exclusive, or high-demand products, allowing one customer to purchase unlimited quantities can quickly affect inventory availability. Per-customer purchase limits help merchants control how much an individual customer can buy.
For example, you can allow customers to purchase only one unit of a limited-edition product or set a maximum of five units per customer.
In this guide, we’ll explain how Shopify customer purchase restrictions work and how KOR Order Limits Quantity can help manage them.
What Are Per-Customer Purchase Limits?
A per-customer purchase limit restricts the quantity a specific customer can purchase according to a defined rule.
For example:
Maximum: 2 units per customer
This can help prevent excessive buying and allow more customers to purchase limited products.
Unlike a basic product quantity limit, a per-customer rule focuses on how much an individual customer is allowed to purchase.
Why Limit Products Per Customer?
Per-customer restrictions can be useful for:
- Limited-edition products: Give more customers a chance to purchase.
- Flash sales: Prevent a few shoppers from taking most of the stock.
- Product launches: Control demand when inventory is limited.
- Promotions: Restrict how many discounted products one customer can buy.
- Wholesale stores: Apply different purchasing rules to specific customer groups.
- High-demand products: Reduce excessive bulk buying.
How to Limit Product Quantity Per Customer on Shopify
Shopify merchants can use a dedicated order-limit app to create advanced purchasing restrictions.
With KOR Order Limits Quantity, you can create rules for products, variants, collections, carts, customers, order value, and weight.
Step 1: Install KOR
Install KOR Order Limits Quantity from the Shopify App Store.
Step 2: Select a Product
Choose the product for which you want to create a purchase restriction.
Step 3: Set the Quantity Limit
Define the maximum quantity a customer can purchase.
For example:
Maximum quantity: 2 units per customer
Step 4: Configure Customer Rules
KOR supports customer tag-based limits, allowing you to apply different restrictions to specific customer groups.
For example:
- Retail customers → Maximum 5 units
- Wholesale customers → Minimum 20 units
- VIP customers → Maximum 10 units
Step 5: Customize the Message
Display a clear message when customers reach the purchase limit, such as:
“You can purchase a maximum of 2 units of this product.”
Step 6: Test the Rule
Try purchasing quantities below and above the limit to ensure the restriction works as expected.
How to Limit a Product to One Per Customer
A one-per-customer rule is useful for extremely limited products, giveaways, promotional items, and exclusive releases.
For example:
Product: Limited Edition Collectible
Limit: 1 unit per customer
This helps prevent individual shoppers from purchasing multiple units and improves product availability for other customers.
Customer Tag-Based Purchase Restrictions
Different customers may require different purchasing rules. KOR’s customer tag-based limits allow merchants to create restrictions based on customer tags.
This is particularly useful for B2B and wholesale stores where purchasing requirements can vary between retail and wholesale customers.
