credits

I'll help you with handling your customer balance in QuickBooks Online (QBO), John. 

We can clear the credit by creating a credit memo and applying it to an invoice. First, let's delete the refund you created by following the steps below:

1. Go to the Sales menu, then Customers. 
2. Find and click the customer's profile.
3. Under the Transaction List, delete the refund transaction you created by clicking the Action dropdown.
   
   

Once done, let's create a credit memo. Here's how:
 

1. Go to the + New.
2. Select Credit memo.
3. In the Customer dropdown, select the customer's name.
4. Enter the credit memo details, such as the date and the amount. 
5. When you're done, select Save and Close.

Then, apply the credit memo to an invoice:
 

1. Go to the + New, then choose Receive payment.
2. Select the customer.
3. In the Outstanding Transactions section, tick the open invoice where you want to apply the credit memo.
4. Under the Credits section, click the credit memos you want to apply.
5. Enter how much of the credit you want to apply in the Payment field.
6. Leave the Payment method, Reference no, Deposit to, and Amount received fields blank.
7. Fill out the rest of the form, including the Payment date.
8. Make sure the total is correct after applying the credit memo.
9. When you're done, select Save and Close.
