Why is opening and closing inventory not reflected in profit and loss

Hello there.

I can see the importance of this matter, and I'm here to provide you with the information you need. Upon checking here on our end, the option to add the opening and closing inventory to the profit and loss report is unavailable. I can see how this would be a great addition to the business report you're trying to generate, and with that said, I recommend sending a feature suggestion to our Product Development Team. When they see your recommendation, they'll evaluate it and consider adding the option for future program updates. I'll write down the steps to get you going:

1. Access your QuickBooks Online company.
2. On the top right-corner, click the Gear icon.
3. Select Feedback and then enter your comments or product suggestions.
4. Once ready, click Next to submit feedback.

Also, you can consider exporting your profit and loss report and manually add the opening and closing inventories to it. You can check this article for more information about exporting reports outside QBO: Export data, reports, lists, and more from QuickBooks Online.

Additionally, here's an article to help you add more details to your report inside QBO: Customise reports in QuickBooks Online.

Please don't hesitate to leave a comment or post here in the Community space if you have any additional QuickBooks-related queries. As always, I'll be here. Ready to help you out again. Stay safe, and have a nice day!
