Hello there, @sdtld.

I understand how beneficial it is for you and your business to be able to easily view an expense by project report. QuickBooks has a lot of built-in reports that you can customize to display the data your business needs. That being  said, let me walk you through in generating and customizing the Transaction Detail by Account report.

1. Go to the Reports menu.
2. Scroll down to the For my accountant section.
3. Double-click on the Transaction Detail by Account report.
4. Click the Customize button.
5. Set the Date Range of the report. 
6. From the Rows/Columns section, click the Group by drop-down arrow.
7. Pick Customer. 
8. In the Filter section, mark the Distribution Account tick box.
9. Select All Expense Accounts. 
10. Click the Run Report button. 

Now, you can see a list of your expense transactions grouped by Project/Customer. You can change the name of the report to match the information it displays.

Also, you can grouped the transactions by Vendor.  By doing this, all the expense transactions that were not billed to your projects will show a blank entry under the Customer column.

Lastly, you can save the customization you've made for future purposes. You can read through these articles on how you can personalize the built-in reports in QuickBooks to match your business needs:
