Can i add multiple books in my qb account login?

One QBO account is for one company file. Consider using QB Desktop to manage multi company files.

Hello bleaze22. Just to add to the valuable info provided by Deity Aplha, the program allows you to manage more than one subscription using the same email address. You can utilize the Switch Company feature that allows you to switch between companies with the same email. This means you'd have to a separate subscription for each company. Feel free to ask other questions. I'll be a message away.
