Quickbooks ... do your homework on the options for each version and make an educated decision. If you have no bookkeeping or accounting background you may want to seek local professional guidance to get educated on what needs to be done, how and when.
Downloaded version is preferred and you can set up as many businesses as you like and you pay one fee once. You do not need a pricey version nor do you need the newest version. I am still using the 2017 program myself in my tax business. If you will use the program for payroll then you will need one 3 years old or newer. You can search online sellers for a better price than you get thru Intuit direct.
Online version will likely require a separate account for each business and a monthly fee for each account.
