So, online accounting software is going to start pouring out. So far, financial application powerhouse Intuit have Quick Books Online which doesn't work on a browser running outside of Windows. This oversight astonishes me - Web Apps are by their very nature cross-platform, all that's required is a sensitive approach to javascript and CSS and a slightly longer Test cycle. A lot of small businesses are using Mac. Among the other contenders we have Bill My Clients which integrates with Paypal and Blinksale which wins the GUI war but has a restricted feature set (it's an invoicing tool above all else). They all come in at about $12/month. All these services wind up being cheaper for Brits than our American counterparts. Needless to say they all support Pounds Sterling.

Surveying this software i get the distinct impression i'm beating around the bush. What we need is a comprehensive collaborative spreadsheeting package for the web. Winner takes all.
