Banking

Hi there, @jenuneekor.

I'd be glad to share some insights about matching your invoice, refund, and bank transactions in QuickBooks Online.

The refund process and the sales recorded will be recorded separately when matching. If the Invoice has been paid, you'll have to deposit it to the Undeposited Funds. Once done, you'll see a positive amount in the bank feed that is detected since it is an Income.

I'll show you how to record the transactions separately. 

Recording a sale using an Invoice:

1. Create an Invoice.
2. Receive the payment and put it to the Undeposited Funds.
3. Deposit it to the Bank. Note: FollowStep 2 in the article.
4. Match it in the Banking page.

To record a Refund transaction:

1. Create a Refund transaction. Indicate the product, amount, sales tax, and other charges. Then, enter the Bank account you've used to refund your customer. You can check this sample screenshot:
   
   
2. Match it in the Banking page. I've added a screenshot for your reference:
   
   

When matching a refund transaction, you'll see a negative amount in the bank feeds since the money is withdrawn from your funds. This is why you're unable to match the invoice and the refund into one bank transaction. If the refund has been already sent to your customer, you'll have to wait for the bank feeds to update so that you can match it.

I've added an article for your future reference when you're ready to assess your business income and expenses through QuickBooks Online: Reconcile an account in QuickBooks Online. This also includes how you can undo the process or fix errors.

Please don't hesitate to tag my name if you need further assistance. It would be my pleasure to help. Take care!
