Yesterday I wrote about Cashboard on tech-intelligence.com, an application that allows you to track your billable time. Today I tell you about Toggl, a clean and simple app that can time the number of billable hours you spend on a client project.

Once you register (for free), create a new project for a new client, and "toggl" the on button. Toggl starts tracking the time spent in a live second by second timer right in the web browser. Hit stop when you're done. Toggl will put together reports - PDF or CSV - for invoicing your clients. (Lifehacker)
