Small businesses outgrow Zapier chains when logic branches, error handling, and audit requirements appear. Custom API integration is often mid-sized hourly work, not a million-dollar programme.
Design pattern: identify system of record per entity (customer, stock, invoice), map fields once, implement idempotent upserts, alert on failure, log payload hashes for support debugging.
Australian context: GST lines, ABN validation, timezone handling for batch jobs, and AU business hours for retry schedules.
Choose Zoho Flow or Power Automate when connectors exist and volume is moderate; custom Node/Python when transforms are ugly or throughput is high.
Test with production-like edge cases: cancelled orders, partial refunds, duplicate webhooks.
