Where does it take money to refund a customer if I did a transaction reversal firectly from the Quickbook payment portal?

Hello there, alanhui.

Once you do transaction reversal directly from QuickBooks Payments, it'll take to your connected bank account. In QuickBooks Online, you can create a credit memo and give a refund to your customer. Let me show you how:

1. Go to the +New button.
2. Select Credit memo.
3. Enter the customer's name.
4. Then, add the items you're giving credit for.
5. Once done, hit Save & Close.
   

Afterward, you can issue the refund in a check. Still, go to the +New button and select Refund receipt, enter the customer's name, and select Check as your Payment Method. Once done adding the details, click the Save and Close button. Lastly, utilize the Receive Payment feature to link these transaction.

I'm adding a link where you can check the ways on how you can void or refund transactions in QuickBooks Payments. 

Feel free to comment back if you have any other questions. Take care and enjoy your day.

OK thanks. So would the reversal create an individual debit entry on my bank checking account register? If so, how should I tie it to the refund?

Also, when I created a refund receipt and choose check as a payment method, QBO automatically sets it to paid. It wouldn't allow me to apply for the credit memo. 

Besides, there is no way to tie the refund to the bank debit created by the reversal.
