It's incredible QB marks this as solved when the Moderator gave absolutely 0 solutions to this.

Unbilled time report is actually very easy to pull up by re-filtering a pre-canned report

I'm using QB Enterprise 23.0

Go to:

Reports

- Jobs, Time & Milage

- Time by Job Detail

Customize report

- Filters

- Billing Status

- Set to "Unbilled"

Gives you a report of all unbilled time by job.
