The models' case: Offers the most complete recovery architecture for typical SaaS businesses by unifying machine-learning retry logic with multi-channel customer outreach, including. The models' main caveat: Cost and feature overhead are excessive for early-stage or micro-SaaS teams under $20k MRR that only require basic webhook-triggered email sequences. The strongest alternative is Paddle Retain — Purpose-built involuntary + voluntary churn recovery combining intelligent card retries with algorithmically timed, personalized customer outreach. Not unanimous: ChatGPT picks Churn Buster; Claude picks Paddle Retain.
