Skildring

Maximum, Minimum and Multiple Quantity for WooCommerce Shops is a simple extension for WooCommerce that lets you set a maximum and/or minimum limit for the number of items that can be added to the cart, and/or force customers to buy a product in multiples of a set number (e.g. 3, 6, 9, …), for each product, per order.

It’s like one of those signs at the grocery store that says, “LIMIT 2 PER CUSTOMER!”, “MINIMUM 5 ITEMS” or “SOLD IN PACKS OF 3”. This plugin will not add a sign like that, but the quantity input field will honor the maximum, the minimum and/or the multiple.

You can set a global maximum, minimum and/or multiple to affect all products in your WooCommerce store or, if you prefer, a different one for each product, individually. Each product’s own setting will always override the global one.

This works for all products in your WooCommerce store: Simple and Variable products.

Customers do not have to be logged in for this to work. This works for guest buyers, as well as logged-in buyers.

This plugin was initially developed by Isabel Castillo and later adopted by Marco Almeida | Webdados / Naked Cat Plugins.

Configuration

  1. To set a global maximum, minimum and/or multiple to affect all products, go to WooCommerce, Settings, Products tab. Click “Inventory”. Scroll down to “Maximum quantity per product”, “Minimum quantity per product” and “Sell in multiples of”. Set your desired values there.
  2. To override this for a single product, go the product’s own “Edit product” page. Scroll down to the “Product Data” box. Click on the Inventory tab. There, you’ll see the same three settings, “Max quantity per order”, “Min quantity per order” and “Sell in multiples of”, where you can set your desired values for that product.

Also works for subscriptions

8. oktober 2020
Thanks for this plugin. We use it along with WP Job Manager and WooCommerce Subscriptions. It ensures that our users can only purchase one subscription plan. Before, we faced the issue that a few users accidentally purchased a plan twice. Thanks for investing your time. 🙂 Florian
