Referralful

Most affiliate tools sit beside your billing system and take its word for it. Referralful is built the other way round: it reads subscription state directly from Stripe, so what a partner earns is tied to what actually happened to the payment rather than to what happened at checkout.

That matters at the edges, where affiliate programs usually go wrong. Revenue that reverses after a refund or a dispute should not stay in an affiliate's balance, and a plan change should change what the next invoice earns them. Getting those cases right from day one costs nothing; retrofitting them later is a trust problem as much as an engineering one.

Setup is no-code. Affiliates get their own dashboard and referral link, attribution runs on a 60-day cookie, and an existing program moves across with a one-click Rewardful import. Pricing is free until your first affiliate, then $19.99 a month on the Starter plan, with no percentage taken out of affiliate revenue.
