It's great to have you here in the Community, @sourceenterprise!
You'll be glad to know that the QuickBooks Online (QBO) mobile app and web version always stay in sync. So, any changes and tasks you make using the app will reflect on the web and vice versa.
Additionally, you can check out these step-by-step video tutorials at Get started QuickBooks Tutorials US to help you easily navigate QBO.
If you have any further concerns regarding syncing your data, feel free to return to this thread. I've got your back.
