Is it possible to set up multiple companies under the same account?

I appreciate your interest in QuickBooks Online for your company, @hp-hollieswellne and 9130 3466 2688 0166. Please note that one QBO account is for one company file. Though, you may use the same email address to manage multiple accounts. 

To start a new business, click this link: https://quickbooks.intuit.com/uk/pricing/. Select the version you prefer, then type in your current login information when prompted.

Here are the steps in managing multiple companies under your existing user ID:

1. Go back to the QuickBooks UK pricing page, then select the subscription you want for your second company. 
2. You’ll see one of two sign-in pages and ask you to confirm the account you want to sign in under. 
3. Select “Yes, that’s correct." if you recently signed in to QuickBooks.
4. If not, select Add another company. When asked, enter the same ID and password you already use for QuickBooks. 
5. Fill out all the information about your new company and you’re good to go.
