Can anyone please help me process a refund to a customer who accidentally paid me twice, before I go insane And tie up with my bank feed ?

Hi there, @dsnash.

You could create a refund receipt in QuickBooks Online to process a refund if you originally recorded the transaction as a sales receipt.

A refund receipt is a money-out transaction that gives back the money to the person who sent the funds. Saying your customer made a payment twice, we'll have to record a refund receipt for payments with invoices. I'll show you how.

1. Go to the +New button.
2. Under Customers, select Refund Receipt.
3. On the Customer menu, choose the name of the customer who made the payment twice.
4. Enter the required info in each field based on the transaction detail of the original invoice.
5. Select a bank account which you would like to take out the refund.
6. Click Save and close.

If you recorded the original transaction as an invoice, you can follow the refund process in this help article.
