Top FirstPromoter Alternatives, Explained

1. Rewardful

4.6· From $49/mo

Rewardful is the default affiliate tool for SaaS billed through Stripe. You connect Stripe, drop in a snippet, and it attributes trials and recurring subscription revenue to affiliates, including renewals, upgrades and refunds, without webhooks of your own. Every plan has unlimited affiliates, a 14-day trial and 0% transaction fees. Plans are tiered by how much revenue affiliates bring in each month: Starter is $49/month up to $7,500, Growth $99 up to $15,000, and Enterprise from $149 at $30,000. Managed payouts are optional, at 3%.

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.
