Hi there, rootznaturalhair444. I'm glad to help you start a new QuickBooks Online (QBO) account under your business name and EIN.
Yes. You can signup for a new QBO account using the same email address as suggested by Fiat Lux ASIA above. Make sure to input the correct billing details along the process. Here's how:
- Open this link: https://quickbooks.intuit.com/pricing/.
- Choose your plan.
- Add payroll (optional).
- Tap on Checkout.

- Select your desired payment method, then follow the onscreen instructions to complete the setup.

If you want to modify your business information, go to the Gear icon, then select Accounts and Settings. You can also open this article for an additional guide: Change your business name, contact info, or EIN in QuickBooks Online.
On the other hand, if you wish to connect your bank or credit cards to bring your transactions to QuickBooks automatically, see this link as your guide: Connect bank and credit card accounts to QuickBooks Online.
I'm pleased to share these details with you today. Give me a shout in the comment section below if you have other QuickBooks questions. Have a good one!
