I hear what you're saying Sonny209. Luckily QuickBooks Online is equipped with multiple ways to find the data that you're looking to view. I have an option that will work well for you.
An Invoice List report can be customized to show amount and whether it's been paid or not. To do this select Customize in the upper right. From the filters, check off Amount and enter the dollar amount into to the corresponding field. To ensure that you're only seeing open invoices in the amount specified, check A/R Paid as well and select Unpaid from the dropdown menu. Select Run report and you'll see any unpaid invoices for the amount that you've entered.
Please let me know if you have any additional questions. I know this report will do the trick.
