The Problem

  • Zapier costs were scaling out of control as volume grew.
  • Complex multi-step zaps were hitting task limits and failing silently.
  • The team had no visibility into what was breaking or why, and couldn't afford to keep paying per-task at production volume.

The Solution

  • Audited all 28 zaps, categorized by complexity and failure risk.
  • Rebuilt each in n8n with proper error branches, retry logic, and parallel execution where safe.
  • Deployed on a VPS with Slack alerting for any failures.
  • Full migration completed with zero downtime — new n8n workflows ran in parallel before cutover.
