Personal and business accounting software in Australia has traditionally been a two-horse race: Quicken versus MYOB. Quicken's latest competitive trick? Moving into the online world with an entirely browser-based version of its software.
QuickBooks Online actually doesn't look much like a web application, since it mimics very closely the traditional desktop package. (Indeed, if you already have QuickBooks installed on the desktop, buying the online version will allow you to work in either online or offline mode, though that might be risky with multiple users.)
At $250 for the first year and $22 a month after that, it's hardly a cheap option. On the other hand, the package includes continuous updates (useful with tax law constantly changing), the option for your accountant to also access your data if you authorise them, and eliminates the need to constantly back up your finance data.
Currently, the online software only officially works with Internet Explorer on Windows, though Firefox apparently goes OK as well. Support for Safari and Chrome (and official support for Firefox) will follow later in 2009.
The service officially launches in August, but if you're curious you can sign up via the link below for notification when it goes live.
