Where Butter Payments wins
Butter's ML retry engine is genuinely good, it's fully hands-off, and 'you only pay when we recover' is an easy yes for a Stripe team. If you're on Stripe and want a fully-managed, performance-priced engine, Butter is a strong pick. But it doesn't touch Square, and its rev-share scales with your success — the more you recover, the more you pay, with no ceiling. (Butter's exact % is set per account; ~20% is a representative figure.)
On Square? This is the one built for you.
Connect Square read-only and see your recoverable revenue in ten minutes — no rip-and-replace, no rev share.
