Quantities and Units for WooCommerce


NOTE: This plugin has been forked from the “Advanced Product Quantities” plugin. It adds decimal quantities support and
units to products. Please don’t attempt to run both plugins simultaneously. It not needed and the universe will
probably implode.

With Quantities and Units for WooCommerce you can easily create rules that restrict the amount of products a user can
buy at once. Set Minimum, Maximum and Step values for any product type and must be valid before a customer can proceed
to checkout. Quantities and Units also bring decimal quantity support to WooCommerce.

This plugin works great with Rapid Order, a fast ordering system for WooCommerce.

The plugin justifies its functions. But, unfortunately, there is not enough technical capacity to translate the plugin into another language
