Hello there, @support-jlchapju.

QuickBooks has an array of reports that you can generate and customize to suit your business needs. However, the ability to run a billable expense report that shows the due date for both invoice and expense transactions. You need not to worry, you can run the Uninvoiced charges report.

1. Click the Reports tab.
2. Enter and select Uninvoiced charges in the Find report by name search box.
3. Click Customize.
4. In the Rows/Column drop-down, select Customer.
5. Go to the Filter drop-down.
6. Tick Transaction Type and select Billable Expense Charge.
7. Select a customer in the Customer drop-down.
8. Click Run report.
