Hello, M-Nabil. 

Using warehouse feature isn't available in QuickBooks Online. As mention above you can utilize a third-part app that integrates with QuickBooks.   

In the meantime, You can visit our QuickBooks Blog and QuickBooks Resource Center. From there, you can see the future developments and the latest news about QuickBooks and what our Product Care Team is working on.    

Feel free to comment below if you have any other questions. I'll be here to help. Stay safe!
