I’ve seen this over and over after partnering with 100+ SaaS companies: the affiliate platform you choose is the single biggest factor in whether your program actually succeeds. In this video, I break down the five non-negotiables your platform has to get right—and the stuff a lot of platforms hope you don’t notice until you’re already locked in. We talk tracking (and why “first-party cookies” can still be misleading), payouts + tax compliance (because nobody wants affiliate admin to become a full-time job), partner experience (one unified login vs a million whitelabeled portals), content-level attribution (UTMs), and why a modern UI actually matters when you’re trying to make fast decisions. I also explain why older networks like Impact (and CJ) routinely underperform for SaaS because of redirect-based “bounce hopping” that gets blocked by iOS/Safari/Firefox and ad blockers—meaning you can lose tracking for ~30–40% of traffic. Then I compare the two real contenders for SaaS: PartnerStack and Dub Partners. PartnerStack gets you about 70% of the way there, but the last 30%—reliable Stripe-native attribution, fast usable analytics, and UTM-based content visibility—is where programs win or lose. Our top pick is Dub Partners because it’s genuinely modern, built on true first-party tracking, has the best Stripe integration we’ve seen, and gives both brands and partners the granular analytics needed to optimize what’s actually converting.
