I created a refund on an order but it is not shown in invoice?
How can I show refund amount on invoice?
Thanks in advance
Do you mean the PDF invoice or the email ?
For the PDF you would need to modify the routine
public virtual void PrintOrdersToPdf(...
Have a look at how it works then add a new line to print the value of order.RefundedAmount
For the email you could enable the OrderRefunded.CustomerNotification template in Message Templates
