Description

🚀 How it works

Runs daily at 06:00 UTC, pulls every Shopify product variant’s stock level,
calculates real sales velocity from the last 7 days of orders, then uses
GPT-4o to predict stockout dates and decide whether to reorder — automatically.

• 🛍️ Fetches all Shopify product variants and current inventory quantities
• 📦 Pulls the last 7 days of orders and computes units sold per variant
• ⚡ Calculates sales velocity (units/day) and estimated days until stockout
• 🤖 AI Agent classifies risk: critical / high / medium / low and recommends reorder quantity (30-day demand + 20% safety buffer)
• 📧 Sends a formatted reorder request email to your supplier for high-risk variants
• 📊 Logs every decision (reordered or skipped) to Google Sheets for inventory tracking
