How to refund a customer
Issuing refunds through Gumroad is - aside from the loss of money - absolutely painless. Simply go to your Customers dashboard and locate your customer by searching for their email address or filtering by the product.
Click on the sale to open their customer drawer. To refund them for the full amount, click the green Refund fully. To offer a partial refund, enter the amount to be refunded in the box, and then click Issue partial refund.
Note that you cannot issue partial refunds on membership products.
Your customer will receive an email confirming the refund, and their credit card account should receive the funds within 5-7 business days. They will no longer be able to download this product, or receive updates from you.
Refunding a customer fully will also delete the rating they've provided to your product.
