Hello @maddymiasmith
It is possible via APP but it is required to enable CCS on the store before using an app.
May i know do you have enabled CCS on your store?
Topic summary
A merchant is experiencing an issue where Shopify doubles the shipping fee when customers purchase items from multiple inventory locations. They want to charge only a single flat rate regardless of how many locations are involved.
Current Setup:
- Store uses both flat-rate and carrier-calculated shipping at checkout
- Products ship from different locations, triggering duplicate shipping charges
Proposed Solutions:
Two app developers offered potential fixes:
-
Shipping Based on Zipcode app - Supports single flat rate for multi-location carts, but requires Carrier Calculated Shipping (CCS) to be enabled
-
ShipMagic app - Uses Shipping Customization rules to prevent double charging; works on Basic Shopify plan but only supports flat rate shipping
-
Bespoke Shipping app - Offers solutions for both scenarios:
- Flat rates: Works WITHOUT CCS (Basic plan compatible)
- Live rates: Requires CCS (minimum ‘Shopify’ plan, free with annual billing)
Status: Multiple solutions available depending on plan level and shipping method preferences. Discussion remains open for implementation.
