Top Rewardful Alternatives, Explained

1. FirstPromoter

4.6· From $49/mo

FirstPromoter covers the same job as Rewardful with a wider billing reach. It tracks recurring commissions from Stripe, Paddle, Chargebee, Recurly and Braintree, as well as no-code platforms such as HighLevel, Kajabi and ThriveCart.

Business is $99 up to $15,000, with unlimited affiliates and a white-labelled portal on your own domain. Enterprise is $149 above $15,000 and adds SSO and managed payouts.

2. Tolt

4.6· From $69/mo

Tolt is the newer, leaner entrant. It offers affiliate links, recurring commissions, a partner portal and payouts, with integrations for Stripe and Paddle only. That is the first thing to check, because Tolt's own FAQ says those are currently the only two supported. In return the revenue caps are generous for the price. Basic is $69/month for up to $10,000 of affiliate revenue (manual payouts). Growth is $99 up to $20,000, and Pro is $199 up to $50,000, both with automatic payouts at a 2% processing fee. Enterprise is quoted beyond that.

3. PartnerStack

4.3· Usage-based

PartnerStack is a different tier of product from the other three. It runs affiliate, referral and reseller programs together, and its main draw is the marketplace: a network of partners already looking for B2B SaaS to promote, so you are not recruiting every affiliate yourself. Pricing is not published and needs a demo and an annual contract. Buyer data puts the median at about $19,600 a year, and reports cite platform fees from around $1,500 a month plus a percentage of partner commissions. It makes sense once partners are a real revenue channel, not while you are testing one.

Handles resellers and referrals, not just affiliates
