Hello, @eekie75.

Yes, you’re right. There’s a bit of difference between the mobile app and the web version of QuickBooks. Our mobile apps are designed to optimize touch interaction and essential on-the-go workflows.

You can manage your customers by creating invoices, estimates, and many more. 

For more information about the feature available on mobile devices, you can check out this related article: Compare mobile app features.

More features are added often, so I encourage you to visit the QuickBooks Blog to check for new updates and functions that we have. 

Let me know if there's anything that I can be of help with your QBO mobile app and or anything else. I'm always here to help. Have a great rest of the day!
