I need to make a list of the invoices that will be delivered to my clients, in order to have control of the invoices that are already in dispatch

I got the perfect report for you that list the invoices that are already sent or not, orlandobp01-gmai.

Let me show you how to open it up: 

1. Go to the Reports menu and look for Invoice List.
2. Click the Customize button in the upper-right hand corner of the report.
3. Scroll-down to the Rows/Columns section and check the box for Sent.
4. Click Run Report.

Let me also share a couple of articles about running reports in QBO for more reference:

• Memorize Reports In QuickBooks Online 
• Reports Included In Your QuickBooks Online Subscription
