You can use any plan of QBO to open many accounts at the same time including QBSE or QBO Simple Start.

The trick is to run more than one browser on your computer. This means that if you are running 3 browsers (eg Chrome, Edge, Firefox) including private/incognito browsers, you will be able to open up to 6 QBO accounts at the same time.
