Fanurio is a time tracking and billing application designed to help freelancers manage their work and be paid for it.

It runs both on Mac OS X and Windows. * Organize your work per client using projects * Mark invoices as paid and track the overdue ones * Mark your work as billable (flat rate, hourly rate) or non-billable * Create partial invoices anytime during the project * Create invoices for single or multiple projects * Customize invoice templates using your own layouts * Import clients from Address Book or other applications * Export data to a CSV or Excel file and import it in other applications * Create backup copies of your data The majority of time tracking and billing applications are developed to serve both freelancers and small businesses in the form of single and multi-user versions.

But freelancers and small businesses have different needs and although some functionality is common in the two worlds, an application that does them all isn't particularly well-designed for any of them.
