Overview
An affiliate program is the closest thing to performance marketing on autopilot: you only pay when someone actually sells for you. For SaaS and digital products it has become a default growth channel in 2026, because creators, newsletter authors, and community owners are actively looking for products worth recommending. Starting one comes down to five steps: set a commission worth promoting (20-30% is the going rate for digital products, and recurring commissions beat one-time for subscriptions), pick tracking software so referrals are attributed reliably, create a simple partner page that sells the program, recruit your first 10-20 affiliates by hand, and automate payouts so partners get paid without you touching a spreadsheet every month.
The software choice matters more than most founders expect. Affiliate tracking touches your checkout, your analytics, and your partners' trust: if attribution silently fails or payouts are late, your best affiliates quietly stop promoting you. The good news is that modern tools have collapsed what used to be an enterprise project into a one-line script and an afternoon of setup. Below we rank the five platforms we would actually use, from dedicated affiliate software to the affiliate features built into modern payment providers.
If you only take one recommendation from this guide, make it Affonso. It hits the sweet spot for indie SaaS and digital products: fast setup, support for modern payment stacks (Stripe, Paddle, Lemon Squeezy, Polar, and Creem), branded affiliate portals, and pricing that does not punish you for growing. We wrote a full, hands-on breakdown in our Affonso review if you want the deep dive before committing.
And if you want to see a live example of the other side of the fence, we run our own program too: the Alternative.tools affiliate program pays 30% per sale. Steal the structure: clear commission up front, an earnings calculator, concrete promotion ideas, and a one-click signup. That is the level of clarity your own partner page should hit, whichever platform you pick.
