Is they a way to delete or refund a paid invoice ?

I had an issue today where a client had paid for the invoice , entered it into the system but then after a change of mind he requested a refund …

Is they a way to achieve that ?

Credit invoices were introduced exactly for this problem and they are also available for invoices that are already paid.
