In QBs projects/estimates I'm wondering if there's any way to set up an automated alert when I get close to the estimated hours on a given project?

Right now, there isn't an option to set up an automated alert for projects or estimates, Hailstorm.

You'll have to manually check the progress of your projects. You can send feedback about the feature that you want.

Here's how:

1. Select the Gear icon at the top, then Feedback.
2. Enter your comments or product suggestions. 
3. Click Next to submit feedback.
    

Your valuable feedback goes to our Product Development team to help improve your experience in QuickBooks. You can track feature requests through the QuickBooks Online Feature Requests website.

I'm adding these articles in case you need them while working on your projects.

• Track hourly labor costs and profitability by a project in QuickBooks Online
• Add existing invoices to QuickBooks Online Projects.

Let me know if you have other concerns by commenting below. I'm always right here whenever you have additional questions about your projects.

Any new developments with a feature like this? This would be very useful
