Pre-Order Inventory Sync for Shopify Using Stocky + Admin API
Shopify Pre-Order Automation with Real-Time Inventory & Arrival Dates
Overview:
Tired of manually managing pre-orders, spreadsheets, and vague delivery timelines? I built a custom Shopify automation that syncs purchase orders from Stocky, updates pre-order inventory in real-time, and shows accurate arrival dates on product pages—without any manual work.
What I Delivered:
✅ Automated sync between Stocky and Shopify every 30 minutes
✅ Pre-order inventory auto-updates at a dedicated “in-transit” location
✅ Arrival dates displayed live via product metafields
✅ Pre-order stock resets when inventory is received
✅ Overselling risk eliminated using Shopify’s multi-location logic
✅ Clean, scalable Node.js app built with rate-limit protection and batch processing
✅ Secure admin override via custom endpoint
