Rewardful

Rewardful attaches an affiliate program to a business that already bills through Stripe or Paddle, and the install really is two scripts. Commissions adjust themselves when a referred customer upgrades, downgrades or cancels, which is the part people get wrong doing it in a spreadsheet. It sees only what those two processors see, so a Gumroad or Lemon Squeezy checkout sits outside it.

Plans are banded by how much revenue your affiliates bring in rather than by feature. Starter is $49 a month up to $7,500 a month from affiliates, Growth is $99 up to $15,000 and adds a branded portal on your own domain, and Enterprise starts at $149 above that. Every plan takes 0 percent of the transactions themselves, has unlimited affiliates and includes the API. Annual billing gives two months free, and there is a 14-day trial.

Somebody selling a subscription product through Stripe or Paddle who wants an affiliate programme running this week. If you sell through Gumroad, Lemon Squeezy or a marketplace, none of the tracking applies to you.
