Project Overview
StockSync Pro is a custom Shopify app that provides real-time bidirectional inventory synchronization between Shopify stores and major warehouse management systems.
The Problem
FreshBox Organics operates across multiple fulfillment centers and was losing thousands of dollars monthly due to overselling and inventory mismatches.
Key Pain Points
- Inventory counts drifting between Shopify and warehouse systems
- Overselling during flash sales and promotions
- No visibility into stock levels across all locations
- Manual CSV imports causing data corruption
Technical Implementation
The app was built using Shopify's App Bridge and Polaris design system for a native admin experience.
// Webhook handler for inventory updates
app.post('/webhooks/inventory', async (req, res) => {
const { inventory_item_id, available } = req.body;
await syncQueue.add('inventory-update', {
itemId: inventory_item_id,
quantity: available,
source: 'shopify'
});
res.sendStatus(200);
});Impact
After deployment, FreshBox reduced overselling incidents by 99.7% and reclaimed 15+ hours per week of manual work.
