PartnerStack vs impact.com: pricing, plans, and which partner platform fits your program

Most comparisons of these two treat them as rival products. They are not, really. PartnerStack sells to B2B SaaS companies running partner-led growth, and its network is full of agencies, consultants, and B2B affiliates who resell or refer software. impact.com sells to consumer and commerce brands running performance marketing at volume, and its marketplace is publishers, media companies, and creators. Ask which is better and the honest answer is a question back: what do you sell, and who would promote it? A B2B SaaS company with a 60 day sales cycle and a Series A budget is buying a different thing than a retailer running thousands of publisher relationships.

The second thing to know is that both of them have closed the door on public pricing. PartnerStack lists three plans, Launch, Growth, and Enterprise, with no figures against any of them, and its own FAQ says pricing depends on program size, feature needs, and support level, confirmed during your demo. impact.com went further: its pricing page now redirects to a demo request form, and there is no pricing or plans page anywhere in its own sitemap, which we checked in August 2026. As recently as July 2026 impact.com published tiers starting around $30 a month, with Essentials at $500 and Pro at $2,500, plus a 2.5% fee on partner-driven transactions. Treat those as historical, not as a quote. What has not changed is that a percentage fee behaves very differently from a flat one: it is cheapest when your program is small and takes a slice of every dollar once it works.

There is a third thing neither platform does, and it is usually what is actually blocking the program. Both are management software, so both assume you already know which companies should be your partners. Partnerships attacks that step first, on flat published pricing from $79 a month.
