Cant login to my business account?

Hello Exporter1000,

Welcome to the Community. QuickBooks Online provides the flexibility needed to easily manage multiple accounts. I'll be happy to provide the info you need so you're on the right track with your work. 

The program allows you to manage more than one subscription using the same email address. Once you've done this you can utilize the Switch Company feature that allows you to switch between companies with the same email. Here's how to switch companies:

1. Select Settings .
2. Under Profile/Your Company, select Switch Company.
3. From the list, select the company you want to switch to.

Let me know if this info helps. I'll be available to assist in case you have other questions.
