I just billed a customers credit card in error and wondering how do I reverse it?

Hi there l.krane,

Thanks for reaching out about your customer payment. Quickbooks Online is a great tool able to help you keep track of sales and expenses so you can know the profit of your company. I can provide some information about refunding your customer.

To refund your customer, go to the +New button, then Refund Receipt. You can enter the information for the refund, and check the option to process credit card to refund to the credit card on file.

If you have any other questions, feel free to reach out here.
