Shipping Editing & Recalculation Logic
Allow customers to update shipping methods, adjust delivery options, and ensure shipping fees stay accurate when orders change — without manual intervention.
⭐ Why This Matters
Shipping-related issues are one of the top reasons customers contact support after checkout.
Common problems include:
- Choosing the wrong shipping method
- Wanting faster delivery
- Shipping price changing after an edit
- Confusion around split shipping
Shipping Editing ensures customers can make these changes themselves, while Shopify recalculates shipping and taxes correctly based on your store rules.
✅ 1. Allow Customers to Change Shipping Method
When enabled, customers can update the selected shipping method after checkout.
What customers can do
- Upgrade to faster shipping
- Switch between available shipping options
- Select different methods when split shipping is enabled

✅ 2. Enable Shipping Recalculation
Enable recalculation of charges
When shipping recalculation is enabled:
- Shopify recalculates shipping fees based on the updated address or shipping method
- Carrier rates, zone rules, and shipping profiles are re-applied
- Free shipping thresholds may activate or be removed
Account Editor does not override shipping prices — it always uses Shopify’s calculated values.

🔄 3. Recalculate Shipping on Line Item Edits
Enable shipping fee update on line item edits
When items in an order are edited:
- Items added
- Items removed
- Quantity changed
- Variant updated
Shipping may change due to:
- Weight changes
- Order value changes
- Shipping profile differences
If this setting is enabled, Shopify recalculates shipping automatically after each edit.

📦 4. Split Shipping (Multi-Location & Shipping Profiles)
Enable split shipping
Split shipping occurs when:
- Products ship from different locations
- Products belong to different shipping profiles
When enabled:
- Orders are split into multiple shipments
- Customers can choose a shipping method for each shipment
- Shipping is calculated separately per shipment
This is common for:
- Multi-warehouse stores
- Heavy + light product combinations
- Region-specific fulfillment
🚚 5. How Shipping Is Calculated (Important Clarification)
Shipping calculations are handled entirely by Shopify, based on:
- Shipping zones
- Shipping profiles
- Carrier rates
- Weight and dimensions
- Market rules
- Discounts (free shipping, promotions)
Account Editor:
- Triggers recalculation
- Displays updated options
- Saves the selected shipping method
Account Editor does not:
- Modify rates
- Create custom shipping logic
- Override carrier pricing
🧾 6. How Shipping Edits Affect Taxes
If tax recalculation is enabled:
- Changing shipping method may change taxable amounts
- Address changes may trigger different tax rules
- Shopify recalculates taxes automatically
This ensures compliance with:
- State-based taxes
- Country-based VAT/GST
- Market-specific tax rules

🧱 7. Fulfillment, 3PL & Locking Rules
Shipping editing may be restricted if:
- A 3PL or OMS has already synced the order
- Fulfillment workflows lock shipping details
- External systems overwrite shipping changes
In these cases:
- Shipping edits may be disabled
- Changes may not sync externally
📎 See Integration Troubleshooting for detailed guidance.
