I started a second business, can i add this new business to my QB account?

One QBO account is for one company file. You can use an old QB Desktop with a non subscription license to manage multi company files.

Yes, Victoria. You can add the new business to your existing QuickBooks Online account. However, there are things you need to learn before achieving this.

When adding another company in QBO, you'll want to subscribe to a new account for this purpose, as QBO permits only one company per subscription. You can take this advantage to switch between companies using the same login credentials.

Here's how to create an existing account:

1. Visit the QuickBooks pricing page.

2. Choose your preferred plan.

3. If you see your existing email under the Signing In window or sign in with the user ID and password you already use for QuickBooks, click the Continue button.

4. Pick your existing company in the Choose Your Company section.

For further guidance, I'm adding this page to help you link your new company to your existing QBO account: Create or add another company file to QuickBooks Online.

Moreover, I'll be providing resources that will assist you in managing your QBO billing and subscription: Manage billing, payment, and subscription info in QuickBooks Online. It also provides details about changing your payment methods and viewing your billing history.

Additionally, we have a knowledgeable team of experts ready to provide immediate support tailored to your business's unique needs. You may want to consider our QuickBooks Live Expert Assisted service. They can help you upgrade your plans.

Congratulations on your second business, Victoria. If you need more help managing both your companies, I'm here to support you and hope your business continues to prosper.

@ChristineJoieRWere you just SOOO desperate to answer that you just went with the nonsense?  

You answered with a "yes" but then proceeded to tell the OP that the answer is actually "No".  

You can't have it both ways.  The answer is NO. Nothing more than just that.  Stop the nonsense.  If yo don't know what the person is actually wanting, needing, or asking, just don't respond.  It makes you look foolish.
