The Live Payment Gateway supports automatic refunds inside WooCommerce.
Please refer to: docs.woocommerce.com/document/woocommerce-refunds for details.
This article refers to the processing of a same-day refund. For refunds processed after the day the transaction was completed, please refer to this article.
A same-day refund (a refund processed before 6 pm) is processed as a void transaction, which is different to a refund. A void acts as a way to reverse a transaction prior to settlement and therefore does not attract a merchant service fee and will not appear on your payment reports, or within the merchant portal.
The transaction information however is still stored in WooCommerce Orders. The Reference ID of the void transaction is also logged under Order Notes.
Note: For accounting purposes, if taxes are enabled the refund must be processed per line to separate tax amounts. Therefore, merchants will not be able to enter the refund amount without adjusting the product quantity if the ‘Enable taxes’ configuration checkbox is ticked.
This setting can be found at WooCommerce > Settings > General (Reference: https://wordpress.org/support/topic/refund-amount-field-grayed-out/)
Service Fee for void transactions
As above, a service fee does not apply to voided transactions.
