Multi-Carrier Shipping Rate Comparison

How It Works

Your Claw pulls new orders from your sales channels, rate-shops across

carriers using a shipping API aggregator, selects the optimal option per

your rules, generates labels, and uploads tracking numbers back to each

platform. What used to take an hour every morning now runs in the background.

What You Get

• Multi-carrier rate comparison (USPS, UPS, FedEx, DHL) for every order
• Rule-based carrier selection: cheapest, fastest, or custom logic
• Batch label generation with packing slip PDFs
• Automatic tracking number upload to Shopify, Amazon, eBay, etc.
• Customer shipping notification emails
• Monthly shipping cost report with savings analysis

Setup Steps

1. Connect a shipping API (EasyPost or Shippo — both aggregate all major carriers)
2. Connect your sales channels for order pulling and tracking upload
3. Set your carrier selection rules (e.g., cheapest for orders under 1lb, UPS Ground for heavy)
4. Configure your return address and package presets (small box, poly mailer, etc.)
5. Run the first batch manually to verify label accuracy

Tips

• USPS Commercial Plus pricing through EasyPost is often 30–50% cheaper than retail
• Dimensional weight matters for UPS and FedEx — provide accurate package dimensions
• For international orders, add HS code classification and customs form generation
• Saturday delivery adds cost but can improve customer satisfaction for Friday orders
• Track carrier performance (damage rates, delivery times) to inform your selection rules
