I rarely post reviews, but MacUpdate is always the place I come to, to read user reviews and to decide if I try and buy a product, or when to steer clear from products.

So here's my contribution.

Today I purchased the Timelog/Grandtotal bundle after trying both for a while.
I come from Stuntsoftware's "On The Job" who is now officially promising this kind of application to come soon, for almost a year now (the anouncement went up in November 2007).
He has been telling me even before that he was thinking in that direction when I mentioned my needs for a program like this.
I consider myself a loyal customer, and thus waited for something to come.
While nothing came, my timetracking and invoicing have become a mess, I invoiced with pages, later numbers, I tried bento, and tried every billing app out there.
Stuntsoftware has many people on the edge of their seat, hoping something will "come soon" but nothing comes, not even a promised blog post.

So, out goes my loyalty, and in comes media atelier.

While I was not instantly overwhelmed by it's ease of use (I find especially Timelog a little hard to understand at times), I was very impressed by the responsivness of the developper.
I contacted him with several questions and I also found a bug in a beta release.
He answered promptly and the bug I found was resolved within minutes.
It shows that the developper cares about his product.
I did not hesitate and instantly bought a license, and I wouldn't have hesitated even if it was twice the price (59 euros for the bundle really is a bargain !)

I'm still learning both programs, but the more I digg into them, the more I'm starting to really like them.

I now regret I didn't make this decision earlier.

I'll also post this review with GrandTotal, since the two actually belong together.

Typical of microsoft, international keyboards still don't work in the release version.

This has been reported over and over through the course of the beta.
