Hi there confinance-osant,
Thank you for reaching out about adding a second QuickBooks Online account to the same login. QuickBooks Online is a great tool able to gives you access to your books from anywhere with an internet connection. I can provide some information about adding a company.
If you're wanting to add a new client account to QuickBooks Online Accountant, you can do so using the methods outlined in this article.
If you want to add another QuickBooks Online to the same login, but not as a client, you can go to the Plans page, and select the plan you want for this account. Then, when asked about the email you want to have on the account, enter the same one associated with your current user. A message popping up will say that the email is already used, and if you want to sign in. Click the option to sign in, then enter your login information. Now, when you log in to QuickBooks Online, you'll see a message asking if you want to log in to Company A or Company B, and you can choose which one to work on at the time.
If you have any other questions, feel free to reach out here.
