How can we monitor profit and loss on separate projects ?

Hello there, PS1211.

In QuickBooks Online (QBO), we can run the Profit and Loss by Customer report to help you track the projects you want. I'll guide you through the process.

1. Go to the Reports menu.
2. In the search bar, type Profit and Loss by Customer.
3. Click on the Customize button.
4. Modify the reporting period.
5. In the Filter section, select the Customer drop-down arrow and choose the project names by placing a check mark. 
6. Hit Run report.

To view each project report separately, go to the Project Reports tab and select Project Profitability. I'll demonstrate how.

1. Go to the Projects menu.
2. Select and click on the project's name.
3. Tap the Project Reports tab.
4. In the Project Profitability section, click on the View link.
5. Set the reporting period.
6. Click Run report.

You can also personalise your report if you want to put more details on it. For your reference, check this article: Customise reports.
