Hello Fadil!

The QuickBooks Desktop versions have more features actually than the online versions. I'll show you how to do billable expenses in QuickBooks Premier version.

Let's enable the option to make the time entries and expenses as billable.

1. From the Edit menu, select Preferences.
2. Go to Time & Expenses.
3. Click on Company Preferences.
4. Place a check in the Make all time entries billable and Mark all expenses as billable checkboxes. Please note that these options will not automatically mark the existing entries as billable. You still have to enable it on the transaction pages.
5. Click OK.

After enabling the feature, you will see a CUSTOMER and a BILLABLE column when you enter time entries and expense transactions. All you need to do is select whom you want to bill an item to and put a check in the BILLABLE field. Example in the screenshot.

When you're ready to invoice the customer, just add the billable entries as shown below.

That will do it. You can read more about this feature by searching for "billable" in the Help (press F1) window.

If you have other questions, please don't hesitate to go back to this thread.
