FirstPromoter vs PromoteKit

FirstPromoter is affiliate and referral management software built specifically for SaaS and other subscription businesses. Its main job is to attribute signups and payments to affiliates or referring customers and calculate recurring commissions correctly over the life of a subscription, including upgrades, downgrades, refunds and cancellations.

It integrates directly with billing systems such as Stripe, Paddle, Chargebee, Recurly and Braintree, and offers a JavaScript tracking script and API for custom setups. Program managers can run several campaigns with different commission rules, tiered and multi-level rewards, coupons tied to affiliates, fraud detection for self-referrals and suspicious traffic, branded affiliate portals and payout management via PayPal or bulk files. Plans are priced by the referral revenue tracked each month, so cost grows with program success, and some extras cost more.

FirstPromoter suits subscription companies whose billing is not only Stripe or that need nuanced commission logic. It does not give you a marketplace of affiliates to recruit from, so you bring your own partners. Rewardful is simpler and popular with Stripe-only startups, Tolt is a newer low-cost option, and PartnerStack or Impact fit larger partner ecosystems with discovery and enterprise contracts. The interface is functional rather than modern, but tracking depth is the reason teams choose it.

PromoteKit is affiliate management software for SaaS companies that bill through Stripe. It is built for indie hackers and small teams: you add one script tag to your site, connect your Stripe account, and PromoteKit tracks referral clicks, attributes signups and calculates commissions automatically from real Stripe payments, including recurring subscription revenue.

Affiliates get a branded portal where they sign up, grab links and coupon codes, and see clicks, conversions and earnings. Founders can set commission rates and durations, approve affiliates, track coupon-based referrals, and manage payouts from one dashboard, with webhooks for connecting other tools. Pricing takes no percentage of affiliate revenue: a free plan covers the first three referrals, a flat-priced Pro plan is among the cheapest in the category, and Enterprise is for larger programs.

PromoteKit fits early-stage and micro-SaaS products that want to start an affiliate program in an afternoon without a large budget. Because it is Stripe-focused and relatively new, teams on Paddle or other billing systems, or those running large programs with complex rules, will find it limited, and reporting is basic. Rewardful is the more established Stripe affiliate tool with deeper features, Tolt is a similar budget alternative, FirstPromoter suits growing SaaS programs, and PartnerStack or Impact serve larger partner ecosystems.
