YITH WooCommerce Deposits and 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 enable the deposit options from YITH Deposits and Down Payments settings.
This will add a deposit section on the product edit page. From this section, you can set the deposit options.
Below, is a sample of a pre-order product added to the cart with a deposit.
