Hello I Found such script http://www.xoopartner.com/ Did somebody test him, it is proper to buy? Maybe some alternative?
I'm not sure how good that script is as I have never tested it. If you want some alternatives then there is a reviews of some here I would guess you are starting an affiliate program and if you are, good luck with it.
loko, xooPartner Affiliate Tracking Software is easy to use. The admin control panel user's guide is coming very soon. Feel free to ask any question.
