YITH Pre-Order for WooCommerce is a free plugin for WordPress that allows online store owners to implement a pre-sale system for their products. This feature helps generate early interest and cash flow by enabling customers to pre-order items before they are officially released. Users can customize the 'Add to cart' button to say 'Pre-order', set release dates, and notify customers via email when products become available. Additionally, store owners can incentivize pre-orders with discounts, making it an attractive option for potential buyers.

The plugin offers flexibility with options to enable or disable pre-order mode on selected products, customize button colors and labels, and manage pricing strategies for pre-orders. While the free version provides essential features, the premium version unlocks advanced functionalities such as automatic pre-order activation for out-of-stock items and exclusive user access. This comprehensive tool is designed to streamline the pre-order process, enhancing the overall shopping experience.
