FirstPromoter signals to top partners that you are cutting costs and not serious about building a strong affiliate program, while Impact lacks reliable tracking and is not built for SaaS needs like recurring revenue or subscription tracking.
Only use FirstPromoter if you have no other choice; skip Impact entirely for SaaS and look elsewhere.
