How do you make Timesheet columns customized

You have a fantastic idea, @needintervention.

I appreciate you taking the time to customize your Timesheet columns. However, this option isn't currently available in QuickBooks Desktop (QBDT).

As a workaround, you can run your Timesheet report and export it to Excel. From there, modify it to include the column you require. I'll show you how.

1. Go to the Reports menu and select Report Center.
2. In the search field, type in Timesheet.
3. Find the Timesheet Report and click Run.
4. Click the Excel button, then select either Create New Worksheet or Update Existing Worksheet. 
5. Follow the on-screen instructions to complete the process.

Another option is to use a third-party app that allows you to customize your timesheet. Simply navigate to the App Center within your QBDT and search for an app from there.
