YITH WooCommerce Deposits / Down Payments is a plugin designed to offer users the opportunity to leave a deposit for a specific order, which they will then finish paying at a later time.
The combined use with YITH Pre-Order for WooCommece allows you to apply a deposit service to your products even when they are in pre-order status.
After installing and activating both plugins, you must configure your pre-order products as described here and set the deposit options from the product edit page.
