Good day, @idf_e276927a-5e0.

Let me share you the info on how to sign up QuickBooks with your Bank of America business bank account.

Here are the quick steps:

1. Go to https://www.bankofamerica.com/smallbusiness/.
2. Select the Small Business tab.
3. Choose Payroll Services.
4. Select the needed payroll product.
5. Select Sign up now. That will launch a Bank of America sign in widget.
6. Log in with your Bank of America credentials.
7. For IFSP, you'll need to fill out the following form. Once filled out, an IFSP setup agent will call you back to set up the account.

You can also add a new user to your Online Business Suite and edit a user once you have created an account. For more details, you can check this all in this link: Bank of America (BofA) user setup for Online Business Suite.

Please let me know if you have additional questions. I'm here to help you anytime. More power to you and your business!
