Product Quantity Rules automatically apply quantity limits to target products, collections, or the entire cart based on rules you define in advance.
Once a rule is set up, it applies automatically to newly added products as well — making it ideal for stores with large catalogs or stores that frequently add new products.
By targeting a collection or all products, you can apply quantity limits in bulk without configuring each product individually. Even stores with large catalogs can manage rules with minimal effort.
You can set limits on the total quantity of products within a specific collection, or on the total quantity of all items in the cart. This is useful when you want to control the overall volume of a purchase rather than restricting individual products.
Example: "Maximum 10 units total from items in this collection" or "Maximum 20 units total across the entire cart."
No technical knowledge required. Just enter a minimum quantity, maximum quantity, and increment in the form to create a rule right away.
When "All products" or a collection is specified as the eligible items, any newly added products are automatically covered by the rule — no need to update your rules every time you add a product.

(※2) When "All products" or a collection is specified as the eligible items, any newly added products are automatically covered by the rule.
