WooCommerce Fixed Quantity is a plugin designed for WordPress users seeking to enforce fixed quantity sales in their online stores. Unlike the default incremental quantity settings in WooCommerce, this plugin allows sellers to define specific quantities for products, such as 100, 200, or 300 units, ensuring customers can only purchase these predefined amounts. This feature is particularly useful for businesses that need to streamline their sales process and avoid confusion over unlisted quantities. Additionally, it simplifies pricing by eliminating the Sale Price field in the General tab, allowing for direct discounts based on the defined fixed quantities.

To utilize this plugin, users must first set a Regular Price in the general tab while adding or editing a product. After that, they can navigate to the Fixed Quantity Price section to specify the allowed quantity list. However, it's important to note that the plugin does not currently check stock levels, meaning that the defined quantities will display regardless of actual stock availability. This plugin is ideal for businesses that require precise control over product quantities.
