Defining Products Eligible for Registration

This article explains how to determine which of your products are eligible for registration within Corso. By leveraging product groups and rules, you can ensure customers only register products that are valid for their purchase channel or location.


With product eligibility rules, you gain control over which items customers can register. This flexibility ensures:

  • Accuracy across sales channels: Only the correct products tied to a specific channel (like Costco, Target, or Amazon) are available for registration.
  • Cleaner customer experience: Prevents confusion when customers attempt to register items not sold through their original purchase location.
  • Scalable management: Product groups let you quickly organize products by tags, collections, or types, making it easy to update rules as your catalog grows.

  • Found on the Settings → Registrations page, below Sales Channels.
  • Each rule is a Register A Product automation. Customers cannot register anything until you add at least one sales channel and at least one Register A Product rule.
  • Each rule offers one Product Group. Customers search only within the products in that group.
  • You can:
    • Offer all products with a single rule that uses an All Products group.
    • Create rules tied to specific sales channels or purchase dates.

Conditions are optional. A rule can be limited by:

  • Registration Channel: the original purchase location the customer selected.
  • Registration Estimated Purchase Date: the estimated purchase date the customer entered.
  • Registration Days Since Purchase Estimate: how long ago that date was.

Example: A rule can specify that registrations from Costco are offered the Costco product group.

Only the first rule that matches a registration is used, so a registration is offered one product group. Drag rules to put more specific rules (such as a channel) above a catch-all rule. If no rule matches, the customer sees no products to choose from.

Product groups are the foundation of eligibility rules. See Managing Product Groups.

  • Built using Shopify product tags, types, or collections.
  • Examples:
    • A Target product group might include all products tagged Target.
    • A Baby Jackets group might include products in a Jackets collection.
  • Groups can be broad (All Products) or highly specific.
  • If a rule has no conditions, it applies to every registration.
  • Useful for stores that want every product to be eligible for registration without channel or date restrictions. Most stores use a single rule like this.
