We have two businesses. Do we need two have two separate QuickBooks accounts or can there be separation between the two on our account?

Hey there, @mthompson-revive. 

It's great to see a new face here. Welcome to the Community. I appreciate you coming to us with your QuickBooks Online (QBO) question. 

If you have two separate businesses, it's best to have two accounts to ensure that your books are correct. Once you get the first business set up, you can easily use the same log in as the first to set up the next account. Here's how: 

1. Visit the QuickBooks pricing page and choose the subscription you want. 
2. Keep going until you get to the payment screen. 
3. Scroll down and hit Sign in next to "Adding a company to an existing account?". 
4. Sign in and finish the rest of the on-screen instructions. 

Note: Don't forget to ensure the company names are different so you can switch between them when you're ready. 

If there's anything else I can help you with QuickBooks, please let me know. I'd be more than willing to lend you a hand. Have a splendid day!

One QBO account is for one company file. You may manage branches/divisions by utilizing the Class/Location feature available in QBO Plus and Advanced. Otherwise you should open a new account.

If our two business have different partners and we want to give access to a partner to one quickbooks a/c but not the other, how can we keep access separate. I opened a new gmail account for the separate business but the new gmail account shows up when I sign into the first gmail account. So if I give a partner the gmail account login, it seems they might have access to my other gmail account.

Hello there, @KPWM1.

When giving access to a QuickBooks account, another user from a different company can't see it if you have a different email associated with it. 

Also, if the other partner didn't know the password, they can't even log in with the account.

I've added this article about different options for user roles and access permissions in QuickBooks: User roles and access rights in QuickBooks Online.
