Syzenlabs Easy Min Max – Minimum/Maximum Quantity, Price Limits & Step Control

Easy Min Max helps you control how customers buy products in WooCommerce.

Create publishable rules that enforce minimum quantity, maximum quantity, step quantity, initial quantity, fixed quantity, minimum price, and maximum price. Step and quantity fields can also use decimal values such as 0.5 or 0.25 when your products need fractional purchase increments. Each rule can be targeted with flexible condition groups, so you can apply restrictions only when they are relevant.

The plugin validates rules on product pages, in the cart, during checkout, and through WooCommerce Store API requests. That keeps the same buying restrictions active across classic and block-based flows.

Key Features

• Set minimum and maximum quantity per matching rule
• Set minimum and maximum price thresholds
• Define integer or decimal step quantity increments
• Prefill an initial quantity on product pages
• Lock matching products to a fixed quantity
• Disable minimum quantity when stock falls below the configured minimum
• Create custom validation messages with placeholders such as [min_quantity], [max_quantity], [min_price], and [max_price]
• Target rules with condition groups using AND within a group and OR between groups
• Validate add to cart, cart updates, checkout, and Store API quantity constraints
• Manage rules from a dedicated WooCommerce admin interface

Flexible Rule Conditions

Easy Min Max supports a broad set of targeting conditions so you can apply rules only when they should run.

You can build rules based on:

• Cart values such as quantity, total, subtotal, weight, coupons, and dimensions
• Product data such as product, category, tag, shipping class, quantity, price, total, weight, and dimensions
• Customer data such as user, role, email, phone, order history, and spending
• Location data such as country, state, city, and postcode
• Time-based checks such as weekday and time window
• Product attributes when attribute data is available

Storefront Behavior

When a published rule matches, Easy Min Max adjusts WooCommerce quantity handling and validation for the relevant products.

Typical use cases include:

• Require customers to buy at least 6 units of selected products
• Limit specific products to a maximum of 2 per order
• Sell an item only in packs of 5 using step quantity or fixed quantity
• Sell measured or fractional products in increments such as 0.5 or 0.25
• Enforce a minimum or maximum product price threshold before purchase
• Apply different restrictions for specific categories, user roles, or locations

Privacy & Data Usage

This plugin connects to external services only from the WordPress admin area and only when an administrator takes an action that triggers analytics or feedback, such as accepting the admin notice or submitting the plugin deactivation survey.

The plugin uses IPInfo to determine the site’s country code for analytics. The request is made when the analytics/feedback action runs. The plugin stores only the returned country code in the analytics payload.

This endpoint is used to help SyzenLabs understand plugin usage and improve the product. When sent, the payload can include the action type, administrator name and email, site URL, product slug, active theme, active/inactive plugin slugs, country code, and optional deactivation feedback selected or typed by the administrator.
