I have 2 companies and would like to have them both under the same login? Is this possible? I already have one company accounts set up and wish to add the second ASAP

Hello and Welcome to the Community! 

It's certainly possible, to do this simply select your desired subscription from our webpage here > add a payroll plan on the pop-up if applicable and select continue > on the screen which appears, see 'Already have an account?' and click 'Sign-in' and continue to buy. 

Once you have setup the account, you will see both listed when signing in and can flick between the two by selecting the main settings wheel > switch company. 🙂

One QBO account is for one company file. You may use the same email address to purchase your second account.
