Wix Invoices Creating a Negative Balance Invoice for Refunded/Returned Products or Services

Currently, it's not possible to create a negative balance invoice when
crediting a customer account to correct a payment error or for a
product/service that was refunded or returned (e.g. refunded store orders,
items returned by your customer, etc.)
