Besides the customization options which are pretty much like a "mandatory" part of such software's, there is a lot more: targeting your campaigns for better reach, A/B testing and strong reporting, automated rewarding. All of that make for a reliable system that keeps an eye on the way your campaign performs while ensuring it looks great as well!

It's perhaps not the cheapest one out there, but I couldn't say it's expensive either as the price is not too bad. However, I can't say it is fitting for very small shops as the smaller you are, the greater is the chance you'll have plenty of expenses already and you won't be too happy about spending around $100 for another software.

If you have the money to spare, then without a doubt it's a nice tool to spend it on - thanks to the fine-tuned analytical assets it can provide, it will without a doubt be a nice companion to support your referral campaigns. It might not be so fitting for smaller companies, but then again - it's all relative so try it out as you won't be regreting it for sure!
