Hello I have an account with you as an LLC, but this year I registered a Corporation INC and have already closed the LLC. The question is, can I continue using the same

I would recommend to convert your old LLC data to a QB Desktop file format and use the trial version to open it for good. Then you will sign up for a new QBO account for your new Corp.

It's generally recommended that you create a new QuickBooks Online (QBO) account for the new entity, William. This is to ensure accurate record-keeping and compliance. I'll explain more details about it. 

When transitioning from an LLC to a Corporation (INC), you also have to change the EIN. Thus, it's crucial to manage each different legal entity as a separate account, ensuring that your records are clear and comply with financial regulations. This also avoids the mixing up of financial data. Always remember that QuickBooks allows one company file per EIN. 

Each company you create requires a separate subscription, but can be accessed with the same login, allowing you to switch between companies easily for efficient management.  Follow the steps below to add a new company:

1. Go to the Sign-in page and select Create an account. 
2. Select a plan, and click Sign In when you reach the Create an Intuit Account page.
   
   
    
3. From there, enter your login credentials, such as the User ID and password. 
4. Click Add another company or create a new company.
5. Please follow the instructions on your screen to complete the setup process.

The next time you sign in, you'll see the list of companies under your Intuit account. For more information, check out this link: Create or add another company file to QuickBooks Online.

Once done, you can now set up your new business entity and add your Corporation's details, including EIN, W9, and company name.
