Thanks for getting back to us, @rogeraf.

To see all the expenses and time you haven't added to an invoice, you can pull up the Unbilled time and expenses report for each customer. This can be done by going to the Project Reports tab in the Project menu.

Here's how:

1. In QuickBooks Online (QBO), go to the Project menu at the left pane.
2. Click the customer's name, then proceed to the Project Reports tab.
3. In the Unbilled time and expenses, select View to open the report. 

Just in case, I'll add these articles for future reference:

• Projects FAQ.
• Set up and create projects in QuickBooks Online.

Please know that I'm only a few clicks away if you have any other questions or concerns. I'll be here to assist. Have a wonderful rest of the day!
