If you want to issue a full or partial refund for payment, now you can do it from the delete payment screen. Processing a refund by staff other than the owner requires them to have the Refund Payment permission. 

Please note the refund will not remove the payment or increase the balance due for the Invoice.

How to navigate: Invoices > Search Invoices (Select Customer) > Click on 3 dots next to the invoice > Delete Payment 

  1. Open the payments for an Invoice from the Search Invoices screen by clicking on the 3 vertical ellipses on left of the invoice
  2. In the Delete Payment dialog click on the refund icon button
  3. Enter the refund amount and click on the Refund button with the amount

That's it, the refund has been processed for more information you can check in the Stripe portal.
