Can I set up inventory items during 30 free trial?

Yes, @info. You can set up inventory items during the 30-day free trial of QuickBooks. The trial version allows you to access and utilize most of the features available in the full version.

Regarding the error message you're encountering when adding an "as of" date, it's possible that the date period you're entering is in the future date as expected by QuickBooks. Please ensure that you are entering the date in the current period to avoid the "invalid date" error message.

If you continue to experience difficulties, we would appreciate it if you could provide more specific details about the steps you're taking and the exact error message you're receiving. This will help me provide you with more accurate guidance to resolve the issue.
