I take care of the bkpg for two separate companies. Currently using QB Pro 2012, but thinking of upgrading. Will NOT be using online subscription - will buy and install the QB 2018 Pro from CD. I do not care if both companies can be open at once - they are not related. So, my question is whether QB Pro 2018 will allow me to have two separate companies from the same installation disc? If not, any other ideas welcome.
