Can I run QB onliine on 2 computers in my home?

Hello wagnerj,

Glad to have you join the Community. I'll be happy  to guide you in the right direction so you can continue to manage your work with ease. The good thing about QuickBooks Online is that your data is stored on the cloud. This means you can access your account from any device(s) simultaneously as long as you have an internet connection. 

Let me know if this info helps. I'll be a message away in case you have other questions.
