Hi there, KPAD.

Thank you for visiting the QuickBooks Community. I'll share details on how creating invoices from timesheets works in QuickBooks Online. Then, I'll ensure to achieve your goal by performing the alternative information below.

When you generate invoices from employee timesheets, the information displayed is based on the data entered on the timesheets. However, removing notes directly when creating customer entries is currently unavailable. This is to ensure that the data remains accurate when switching from one transaction to the next.

Meanwhile, you can manually delete or filter out the notes when creating customer invoices from employee timesheets. To do this, you'll have to go to the Description column and ensure that the field is blank. I added screenshots below for visual reference.

Lastly, you may refer to this article to see different details on how the Sales page gives you a great at-a-glance view of all the status of your sales transactions like open and paid invoices: View sales transactions.

You can always get back to the thread if you have any other questions about creating invoices in QBO. I'm always around to help, KPAD. Have a great day!
