I reviewed quite a few affiliate platforms before settling on Impact, and it quickly became chaos from the start. First the sales rep I spoke with promised me the world only to not deliver on most of what was promised when we finally signed on. From there, my first year with Impact was riddled with problems, all of which were easily surmountable except for the fact that I couldn't get any support from Impact directly which is the main reason for the rating of my review. I had some technical issues that I needed Impact's help to resolve which persisted for months while their support team either replied with ramblings that clearly showed they didn't understand the problem and completely missed the point or left me high and dry for weeks at a time. My first year with Impact was down more than it was up, and they are by far one of the most difficult companies I've ever had to work with. I also lost a lot of business from affiliates that were frustrated and not willing to wait months for me to resolve tracking issues, and I don't blame them. I still believe Impact, from a pure software standpoint, is one of the best affiliate programs out there and the platform is capable of some great things, but none of that matters if the platform doesn't work. If anything goes even slightly wrong and you need support, everything will quickly fall apart. If you have your own development team that can autonomously solve problems, then this app is likely a good fit for you. Otherwise be weary, any issues that crop up will likely cripple your program for months on end.
