Whilst the excellent Blinksale has been getting a lot of plaudits recently, I only just discovered Side Job Track (launched in November 2004), which is in many ways just as noteworthy. It exists to track progress on projects and jobs for freelance, part-time, or small business workers, and it’s really pretty good; simple to use with excellent help and notifications – it’s very consistent about letting you know what you’ve just done, and what will happen when you click something. The only slight problems are that the invoicing is a bit less awesome than Blinksale, and that it’s very focused on building up lists of standardised “services”… when many people are consistently doing bespoke work. Still, worth checking out.
