Carrier Calculated Services (CCS) allows real-time shipping rates from uShip to be displayed to your customers at the Shopify checkout. Having CSS enabled is essential for the uShip app to function properly, as it needs to calculate and display accurate shipping rates based on the item's weight, dimensions, and delivery location.

Verifying CCS is Enabled

Important: Carrier Calculated Services (CCS) is not automatically enabled on all Shopify plans. The exact plans that include CCS and any associated costs can change, so it's best to check directly with Shopify for the most up-to-date information.

To verify that your Shopify account has CCS enabled:

1. Go to your Shopify admin panel
2. Navigate to Settings > Shipping and delivery
3. Look for the "Carrier calculated shipping rates" section
4. If you don't see this section or it's not enabled, contact Shopify support
