Questions,
answered.
Can I switch from ProsperStack?
Yes. Connect Stripe, install SaaSFunnels with one set of instructions for your AI coding tool, and start from the Cancellation or save template. Setup drafts it from your real plans, so you can compare offers before you turn your current flow off.
How is pricing different?
ProsperStack prices by cancellation sessions: Grow starts at $200 a month for 50 sessions, with $75 for each 50 more, and A/B testing starts on Prosper at $750 a month. SaaSFunnels prices by events a month: Builder is $0 plus 3% of Funnel revenue, and paid plans start at $97 a month with no fee.
Which billing systems do you support?
Stripe. SaaSFunnels reads your plans, prices and subscriptions from Stripe and confirms every result there. ProsperStack lists 14 billing systems plus a custom integration, so it fits teams on Chargebee, Recurly or Braintree.
Does either tool measure against customers who saw nothing?
SaaSFunnels does, with control groups on Scale: a share of customers sees no Funnel, so you see what each Funnel added. ProsperStack’s A/B tests compare one offer or flow against another.
Can I run both during the switch?
Yes. Keep your ProsperStack flow live while you build the Cancellation or save Funnel, then move one segment at a time and compare. Funnels for sign-up, onboarding, conversion and upgrades don’t overlap with your cancel flow, so they can go live on day one.
