Where ProsperStack wins
ProsperStack's cancel-flow builder is polished, with A/B testing and AI offers on higher tiers, and it integrates with a huge range of billing platforms. For a Stripe/Chargebee team focused on active-churn save flows, it's a capable tool. Recoup is narrower and Square-native: it does failed-payment recovery + dunning for Square, flat-priced, without the enterprise price tag.
