iDevAffiliate

It has literally so many functions that it would take 2 hours to write about them all. I would pinpoint mainly though that with the extent of features it packs, its' interface looks pretty straightforward and easily manageable. That being said, it can be integrated to the website easily and you can customize the options the way you like it - there are many options you can provide to your affiliates, making it very flexible.

There are some who might say it costs too much but I can't agree with that. Actually, it's impaccable tool considering you can spend $400 one time and get EVERYTHING it has to offer! Not too shabby at all, right? Well, that's the main reason I believe there's nothing bad about this tool.

Even the commissioning structure is extremely flexible - you can tailor it to fit your needs and to suit your affiliates. There are so many options available with iDev, that you will be surprised. It's definitely worth the price and most likely you'll be wanting the full-package with one-time fee as in the end it will be well worth it.
