I have subscribed with Quickbooks online plus and expecting that project option is included based on the advertisement though it doesnt have project option

You've made the right choice, @markgalapin13-gm. The project option is available for QuickBooks Online (QBO) Plus. You'll be able to select it by activating it first in the Account and Settings page. I'm here to guide you how.

The Projects feature in QBO helps your business in organising and tracking all your project income, expenses, and profitability. Let's turn it on so its menu will appear in the main navigation bar.

1. Go to the Gear icon.
2. Select Account and Settings.
3. Go to the Advanced tab.
4. Find the Projects section. Click it to expand.
5. Select the Organise all job-related activity in one place checkbox.
6. Click Save, then OK to confirm.

Once done, you can create your very first project, add income and expenses, and then track your profitability. For the step-by-step guide, you can refer to this article's Step 2-6: Set up and create projects in QuickBooks Online.

You can learn more about the Projects feature in QBO by checking out this article: Projects FAQ.  It contains answers to the most frequently asked questions about it.

Please let me know if you have other concerns. I'm just around to help.
