PartnerStack: Pricing, Features & Alternatives

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.
