Today I acquired QuickBooks Plus, excellent Programa, but it turns out that the one I occupy, is the one that can be added by several Companies. How can I get it?

Thanks for trying QuickBooks Online Plus, imgaccesoriosyma.

In QuickBooks, we can only add one company per subscription. However, if you want to add another company, we'll have to purchase a different QuickBooks account and then we can use the same credentials.

From there, we can easily switch between accounts.

If you want to revert or cancel the subscription, I'll show you how:

1. From the Gear icon, select Account and settings.
2. Go to the Billing & Subscription tab.
3. In the QuickBooks Plus section, click Cancel. subscription.
4. Select Continue to cancel, and then Continue to cancel again.
5. Click  Submit and cancel subscription.
6. Select Got it.

Feel free to get back to me if you still need help. Take care!

Consider using the QB Desktop US or CA version with a one time license to create and manage multiple company files. Then you may deploy a private cloud to let your mobile users access the data files.
