Hello there, Finance.

You have the option to manage multiple companies within your QuickBooks Online (QBO) account, but a separate subscription is required for accurate tracking of each company.

For details on how to subscribe, you can follow these steps:

1. Go to this link in your web browser: https://quickbooks.intuit.com/choose-country/.
2. Select your country.
3. Choose the appropriate product. 
4. Select Start Free Trial or Buy Now.
5. On the next screen, you’ll get the option to either continue to create a free trial or buy now for a discounted price.
6. Since you already have an account with Intuit, select Add another company.
7. Enter your Email Address (User ID) and Password.
8. Choose Add new company.

For more information on creating a new company in QBO, you can refer to this article: Create or add another company file to QuickBooks Online.

Once your account is set up, you can easily switch between companies.

That’s all you need to do, Finance! If you have further questions about creating a new company, feel free to ask. I'm here to help in any way I can.
