Set minimum, maximum and step quantity rules for WooCommerce without a complex pricing plugin.
Overview
MinMax Purchase Rules for WooCommerce helps store owners control how customers purchase products without installing a complex pricing or wholesale plugin.
The plugin lets you set simple and practical purchase rules for products, categories, the whole cart and order amount limits. It is built for real WooCommerce stores that need reliable minimum quantity, maximum quantity and step quantity validation at cart and checkout.
Use it to require products to be purchased in packs, set wholesale category minimums, prevent unusually large cart quantities, or enforce minimum and maximum order amounts.
Main features:
- Product minimum, maximum and step quantity rules
- Category minimum, maximum and step quantity rules
- Cart total quantity limits
- Minimum and maximum order amount rules
- Editable error messages
- Rules overview for store administrators
- Classic Cart and Checkout validation
- Block Cart and Checkout validation
- HPOS compatible
- No license key or external activation server
The plugin focuses on stability and practical purchase validation. It does not change prices, add discounts or replace WooCommerce stock handling. All purchase restrictions are validated server-side, so customers cannot bypass the rules by changing the browser UI.
Typical use cases:
- Require a product to be purchased in packs of 6 or 12
- Set a minimum quantity for wholesale categories
- Prevent a product from being purchased above a set quantity
- Require a minimum cart quantity before checkout
- Block orders below or above a specific order amount
- Show clear customer-facing validation messages
