🚀 Real-World Use Cases

🚨 Use Case 1: Prevent Overselling Between Shopify & Amazon

The Problem: You sell the same products on Shopify and Amazon. A customer buys your last unit on Amazon, but it still shows as "in stock" on Shopify. Result: overselling, angry customers, and hours of manual refunds.

How Inventory Hub Sync Solves It:

• Connects all your sales channels in one place
• Detects real-time stock changes across platforms
• Automatically updates inventory levels to prevent double-selling
• Flags conflicts and discrepancies for immediate resolution
• Generates detailed reports showing sync status per SKU

Example Input:

{
  "channels": [
    {
      "type": "shopify",
      "name": "Shopify Store",
      "storeUrl": "https://your-store.myshopify.com",
      "apiKey": "your_key"
    },
    {
      "type": "amazon",
      "name": "Amazon Seller Central",
      "sellerId": "your_seller_id",
      "role": "source"
    }
  ],
  "syncMode": "inventory",
  "dryRun": false,
  "conflictStrategy": "flag"
}

What You Get: A comprehensive report showing:

• 487 SKUs synced successfully
• 12 conflicts detected (stock mismatches)
• 3 SKUs at critical levels
• Real-time alerts for each platform

📊 Use Case 2: Sync Hundreds of SKUs After a Mass Price Update

The Problem: You update prices in your main system (Shopify). Now you need to propagate those changes to Amazon, eBay, and WooCommerce. Manual copy/paste takes hours and introduces errors.

How Inventory Hub Sync Solves It:

• Define your "source of truth" channel (e.g., Shopify as master)
• Launch a single sync run
• Automatically calculates and applies all price/inventory changes
• Validates updates before pushing to avoid broken data
• Creates audit trail for compliance and troubleshooting

Example Input:

{
  "channels": [
    {
      "type": "shopify",
      "name": "Shopify Master",
      "role": "source"
    },
    {
      "type": "woocommerce",
      "name": "WooCommerce B2C",
      "role": "target"
    },
    {
      "type": "ebay",
      "name": "eBay Outlet",
      "role": "target"
    }
  ],
  "syncMode": "inventory_and_price",
  "dryRun": true
}

Why dryRun: true Matters: Your operations team can preview exactly which SKUs will change, on which channels, by how much. It’s like a "simulation mode" for inventory management—perfect for risk-averse retailers.

🙋 Best For

• Retailers with 2+ sales channels (Shopify + Amazon/eBay/WooCommerce)
• E-commerce ops teams juggling multiple platforms
• Companies that have suffered from overselling or stock discrepancies
• Businesses scaling fast and can't manage inventory manually anymore

❌ Not For

• Inventory systems already perfectly synchronized (rare!)
• Businesses with <100 SKUs managing stock in a single system
