Can I add another business to my quickbooks account?

Hello Lisa, Thanks for your question. As the user above advised it's the case you need a separate subscription for each business. You can when you sign up online select the already have an account and use the same user if/email and password so that you have the ability to switch between companies easily in the product.  If it is different branches you could categorise them into locations or classes rather than have additional subscriptions(through the plus package) Any questions just reply to this thread.
