Stack that stays small
Shopify inventory webhooks + Sheet log.
Tools named here: Shopify, Zapier, Google Sheets. Prefer official docs and native features before adding another SaaS.
Ship the automation
Set inventory thresholds per SKU in Shopify.
Zap low stock → email/SMS + Sheet row.
For POD, monitor base-cost or supplier downtime notices.
Weekly: clear false alarms and adjust thresholds.
Keep it honest
Alert on velocity, not only absolute count, for fast movers.
Automations should reduce decisions and errors — not hide broken processes. If a Zap fails weekly, fix the process or delete the Zap.
