Hi @suzyQ1,

Thank you for taking your time in posting a question here in the Community.

At this time, the QuickBooks Shipping Manager feature is exclusive to QuickBooks Desktop and QuickBooks Desktop Point Of Sale. 

I suggest checking the QuickBooks App Store and search for a 3rd party app that will enable you to have the same features as the Shipping Manager.

I also recommend you visit this page from time to time: The QuickBooks Blog . It lists the new features released for QuickBooks Online, every month. 

If you have other queries, simply drop it in the comments below. I'll get back to you as soon as I can.
