We've released a new feature, "Per-Product Quantity Limits," that lets you set different quantity limits for each product or variant.

Previously, each Quantity Rule consumed one checkout rule, which limited you to a maximum of 25 types of quantity limits. With the new Per-Product Quantity Limits feature, only a single checkout rule is consumed no matter how many hundreds of products or variants you configure. This allows for fine-grained settings without worrying about the number of quantity limit types.
In addition, the previous Quantity Rules applied limits in bulk based on conditions such as collections, product tags, or all products. With the new Per-Product Quantity Limits feature, you can configure products individually one by one, enabling more detailed and precise limits.
Key Features
- Set minimum quantity, maximum quantity, and increment individually for each variant
- Set an upper limit on the total quantity across all variants (total quantity limit)
- Exclude specific variants from the total quantity calculation
- Only 1 checkout rule is consumed regardless of the number of configured products

(*1) This can be handled by creating individual rules, but each rule consumes one checkout rule.
(*2) If "All products" or "Collection" is specified as the target product, newly added products will automatically be subject to the quantity limit.
