I am an independent IT consultant, and at some point, at teh beginning of 2006, I found myself in dire need of a good time tracker that could produce invoices.
I searched around and tried a few demos, but none did what I needed.
Eventually I came across OfficeTime beta 0.5. It was pretty good. Didn't do quite ALL that I needed, but was enough, and the price was right! What really made all the difference was that I wrote Stephen with my requests and suggestions, and he wrote back! Not only that, but in time he did implement a number of the features I required. Particularly important for me was the ability to track several projects simultaneously, since the nature of my work allows me to do that.

For me it was an unrequested but most welcome feature that OfficeTime was also able to produce invoices on demand very easily, with graphics of the time shares occupied by each project. It certainly made my billing a lot easier.
Another unlooked-for bonus was that since using OfficeTime I have been able to organize my time much more efficiently, easily keeping track of each project even if I interrupt them and resume them later. And also having the software and being able to show how it works has saved me a few arguments with the clients, since they can plainly see that the time invoiced is exactly as recorded.

It has been most satisfactory to see the evolution of OfficeTime into a robust, stable, and feature packed application that not only has improved steadily with each release, but also has maintained its original excellent level of support and aperture to client feedback.

Kudos to Stephen for a job superbly well done!
