Clarity Free Edition is a freeware customer relationship management (CRM) program which offers a full range of small business type functionality in a decent enough interface. It’s not beautiful by any stretch of the imagination, but it looks like it’ll do the job.

As well as a contact manager, you get a To-Do activities function tied to a calendar as well as quoting and invoicing modules, which should be enough for most small firms to manage their business.

The free version is limited to single user, and you only get a range of 11 reports for outputting to printer or file, as opposed to the custom report builder and things like the price list generator you get in the full versions. Nevertheless if you’ve got a small firm which needs to computerise quickly and cheaply, this is definitely worth a look.
