↑ Back to top

To configure quantity rules for a product:

  1. Edit the product.
  2. Navigate to the Product Data > General tab.
  3. Locate the Quantity Rules section.
  4. Configure the Minimum Quantity, Maximum Quantity, Group of and Exclude from options.
Editing product quantity rules.

Minimum quantity — Minimum required quantity for this product per order.
Maximum quantity — Maximum allowed quantity for this product per order.
Group of — Enter a quantity to require this product to be purchased in multiples.

If you have defined order and category rules, you can tick the Exclude from checkboxes to skip individual products when evaluating order and category rules:

Exclude from: Order rules — Exclude this product from order quantity and order value rules.
Exclude from: Category rules — Exclude from category Group of rules. Automatically enabled when a a Group of rule is set for a product.

When a Group of rule is set for a product, then category Group of rules do not apply to this product.

Variable Products

When editing a Variable product, an additional option appears under Product Data > General > Quantity Rules called Combine Variations.

  • When this option is disabled, each variation will inherit the rules you have defined in the Quantity Rules section.
  • When this option is enabled, the specified quantity rules are applied in the cart to all variations of this product.

For example, if a Maximum quantity of 5 has been set on the parent and Combine Variations is disabled, you must purchase at least 5 units of each individual variation. If Combine Variations is enabled, it is possible to satisfy the rule by adding 2 units of a variation and 3 units of another.

Variation Rules

When Combine Variations is disabled, it is possible to define a different set of quantity rules for individual variations:

  1. Navigate to Product Data > Variations.
  2. Locate the variation you need to edit and expand its settings.
  3. Tick the Quantity rules box.
  4. Edit the Minimum quantity, Maximum quantity, Group of and Exclude from fields.
  5. Save your changes.

When Combine Variations is enabled, the rules you have specified will be validated in the cart/checkout pages only.

Order Rules

In addition to product-level rules, the extension allows you to set up minimum and maximum Order quantity and Order value rules under WooCommerce > Settings > Products > General:

Setting up order rules.
