Hello bernardlarbie-gn,
It's great to have customers like you connect with us here in the Community. I'll be happy to share more info about navigating the program so you can enjoy the rest of the amazing features offered in QuickBooks.
Once you've completed an invoice, you can get back to the main window (Dashboard) by clicking on Intuit QuickBooks logo that appears on the top-left corner of your QuickBooks account. You can also click on Dashboard right from the left navigation menu as this will bring you back to the main window. In case you'd like to learn more about using shortcuts to help speed up navigating the program, check out this helpful article here: Keyboard shortcuts for QuickBooks Online.
Try this out and let me know how you make out. I'll be looking forward to your response. Otherwise, enjoy the rest of your week!
