Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The simplest answer is, MYOB Basics (quoting) "integrates with your MYOB Accounting software".
But that is advertising copy and lacks details. How do you want it to integrate? to use the same data files interchangeably, or at least interconvertibly? or some other way?
(By the way, a warning: Windows XP is outdated, discontinued, no longer suppoted. Unless you are using it strictly off the net, without Internet connection, no matter how it is configured and protected, it will be hacked into. Windows 7 is usable and quite safe enough to use online, still, and is probably available quite cheaply to install legitimately, too.)
