Can you sell items and refund items in one transaction in quickbooks online?

Hi, @live posh.

I can see the importance of recording your transactions in one receipt. At this time, you need to enter a separate entry for the refund and the new sales. I'll guide you on how.

First, enter a check or refund receipt for the refunded sales. 

1. Sign in to QuickBooks.
2. Go to the +New icon, then click on Refund receipt.
3. Fill in the details, then save the transaction.

Then, enter an invoice or a sales receipt for the new sales.

1. Select Invoice or Sales receipt from the +New icon.
2. Enter the sales information.
3. Save the transaction.

If you're using an invoice to enter the new item, here's how you record a payment: Record invoice payments in QuickBooks Online.
