Good day, @j_bithell-hotmai.
I'll help you delete the invoice payment in your QuickBooks Online (QBO) account. Here's how:
- Go to Sales and select All Sales.
- Look for the payment, then click the transaction to open.
- From the Receive Payment window, click More at the bottom of the screen.
- Select Delete and click Yes to confirm.
That should do it.
I'm also including this article as an additional resource you can in reviewing your sales and inventory status: How to see your best sellers, what’s on hand, the cost of goods, and more.
If you need anything else, feel to post your concern down below. I'll be more than happy to assist you. Keep safe.
