FirstPromoter vs PartnerStack

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.

PartnerStack is a partner relationship management platform for B2B SaaS companies, based in Toronto and originally launched as GrowSumo. It lets software companies run affiliate, referral, reseller and agency programs in one system, and differs from most affiliate tools through its marketplace: a network of partners actively looking for SaaS products to promote.

Companies recruit partners from the marketplace or invite their own, onboard them with tailored resources and training, and track clicks, leads, deals and subscriptions through integrations with Stripe, Chargebee, Recurly, HubSpot and Salesforce. Commissions can be one-time, recurring or tiered, and PartnerStack pays partners globally in consolidated payouts, taking on the administrative work of tax forms and currencies. Reporting shows partner-sourced revenue, and partners get a single dashboard across every program they join. Pricing is quote-based with annual contracts.

PartnerStack fits growth-stage and established B2B SaaS companies that treat partnerships as a real revenue channel and want access to an existing partner network. Early-stage startups usually find it too expensive and complex for a first affiliate program; Rewardful, Tolt and FirstPromoter launch faster at flat monthly prices. Impact.com covers broader partnership types beyond SaaS, and Crossbeam focuses on account mapping between partners rather than payouts.
