How to Set Up Lifetime Purchase Limits Per Customer

Customer Purchase Limits let you restrict how many times a customer can buy specific products across all their orders - not just per order. This is perfect for limited editions, one-per-customer promotions, or preventing bulk resellers.

How It Works

Unlike standard order limits (which reset with each order), Customer Purchase Limits track cumulative purchases per customer:

1. Customer places an order
2. The app records their purchase in their customer profile
3. On future orders, the app checks their history against your limit
4. If they've hit the limit, checkout is blocked with an error message

Setting Up a Customer Purchase Limit

1. Go to Order Limits in the app
2. Click Create new rule
3. Select Customer Purchase Limit as the rule type
4. Configure your limit:
   • Maximum Quantity: The total number of items a customer can ever purchase
   • Maximum Spending: The total amount a customer can spend (optional)
5. Choose which products this applies to:
   • All Products
   • Products with Specific Tags
   • Selected Products
   • Selected Product Variants
6. Set guest customer behavior (see below)
7. Save the rule

Guest Customer Options

Customer Purchase Limits require customer identification to track purchase history. For guest customers, you have two options:

• Allow purchases without limits: Guest customers can checkout without restrictions. Use this if you want to track logged-in customers but not block guests.
• Block and require login: Guest customers must log in to purchase eligible products. Use this for strict enforcement.

Grouping Options

• Any Item: Limits apply to all eligible products combined (e.g., max 3 items total from your "limited edition" collection)
• Product: Limits apply separately per product (e.g., max 1 of each limited edition product)
• Product Variant: Limits apply separately per variant (e.g., max 1 of each size/color)

Viewing and Resetting Usage

You can view a customer's purchase history for any rule by clicking "View usage history" on the rule edit page.

To reset limits for all customers on a rule, use the "Reset all limits" option. Note: This resets for everyone, not individual customers.

Common Use Cases

• Limited editions: "Only 1 per customer, ever"
• Sample products: "Maximum 2 samples per customer lifetime"
• Promotional pricing: "Discounted price available for first 3 purchases only"
• Anti-reseller protection: Prevent bulk buying across multiple orders
