Heirview is a revenue intelligence platform that recovers involuntary SaaS churn. Pruning Labs built its intelligent card-retry state machine driven by bank decline codes, zero-login recovery links, and real-time leak telemetry - on Go, Temporal, TimescaleDB, and the Stripe API.

The problem

SaaS teams lost four to nine percent of monthly recurring revenue to blunt dunning emails and broken webhooks. Failed payments were retried on a fixed schedule regardless of why they failed.

A card reported as stolen and a card that hit a daily limit are entirely different situations. Retrying both at the same interval wastes attempts on one and annoys a paying customer on the other.

What we pruned

• Generic dunning email blasts pruned
• Bloated analytics dashboards pruned
• Fragile cron retry jobs pruned

What we engineered

• Intelligent card retry state machine driven by bank decline codes
• Zero-login payment recovery links
• Real-time leak telemetry streamed to Slack and webhooks

How it is built

• Every recovery attempt is a durable Temporal workflow. A deploy, a Stripe outage, or a network partition mid-run resumes at the exact step it stopped, with full history.
• Retry timing is derived from the issuer decline code rather than a fixed schedule, so hard declines stop immediately and soft declines are retried when they are likely to succeed.
• Idempotency keys on every charge attempt make double-billing structurally impossible, not merely unlikely.
• Payment events land in TimescaleDB, which is what makes leak telemetry queryable in real time instead of overnight.
