Earlier versions of Quickbooks - how far back?
Hello, I am a newly Certified QB Pro Advisor in the process of starting my accounting and QB consulting business.
I received the Premier Accountant 2009 with my enrolment for the Pro Advisor program.
I realise that I will also need to get older versions of QB to serve clients that have not upgraded. Any suggestions regarding how far back I should go re earlier versions and where to purchase the older versions.
Thanks
