Welcome to Community, harryn1.

I'm here to help and ensure to keep you up in running your business. 

You can sign up for a new QuickBooks Online (QBO) account using the same login credentials.

Here's how to subscribe to another company:

1. Go to: https://quickbooks.intuit.com/online/.

2. Choose the version of QuickBooks that best fits your business.

3. You can buy now or sign up for a 30-day free trial.

4. Since you already have an account with Intuit, select the Add another company? located at the top of the screen.

5. Enter your Email Address (User ID) and Password.

6. Select Add new company.

Then, you'll have the option to switch to different company files. Simply click on the Gear icon, then choose Switch company. It will take you to the company selection screen. All of your active and canceled files will be shown there.

When it comes to billing issues, we have a specific department that can assist and handle them for you. You can use our Contact feature to get in touch with our Customer Care team. From there, you can select your preferred support method.
