Think of a task that your small business would love to automate, and chances are that there is some sort of cloud-hosted application that might be meet those needs. But sorting through all the options can be overwhelming.

Another resource you might consider consulting to research your cloud options is AppClick, which actually has created more than 20 country-specific sites listing cloud business applications (although not necessarily just for small businesses). (You can also make your purchases there.)
AppClick represents many of the categories listed above, along with these additions:
Business management and analytics
Help desk management
Legal and law
Project management and planning
