How to issue refunds:
First, click on the Invoice ID.
This will open a detailed view of that invoice.
Click on the Three dots icon adjacent to the Invoice download button.
Once you click on the Three-Dots icon, you will see a drop-down menu.
In that menu, select "Issue Refund".
Once you click on Issue refund, you will see a dialogue box.
In that dialogue box, you can enter the amount that you wish to refund to your customer.
It is your choice whether to issue a full refund or a partial refund.
Just enter the amount that has to be refunded and that amount will be refunded to your customer.
Also, you can mention the reason for the refund as well on the same dialogue box.
Finally, click 'Issue Refund'.
That is all.
The added amount will be sent as a refund to your customer.
