YITH WooCommerce Account Funds allows all users to have a virtual wallet for their purchases.
Users make a deposit and their sum gets converted into virtual funds that can be used to purchase from your store, avoiding any kind of transaction before purchase.
The integration of these two plugins allows adding credit to customers’ wallet automatically when reviewing a product. The option is available when using the Review for Discounts module.
When creating the coupon in Review for discounts > Coupon, you can select Add funds in Coupon settings > Discount type and enter the amount in the related field.
For further details about YITH WooCommerce Account Funds settings, please refer to the official documentation.
