Third-party shipping carrier accounts and availability

To use carrier-calculated shipping (CCS) in Shopify, you need a Shopify plan that includes this feature and an account with a supported shipping carrier. Connecting your carrier account lets you display real-time shipping rates from that carrier at checkout.

Troubleshooting carrier account rates

If your connected carrier account isn't returning the rates that you expect, then review the following common issues and solutions.

Troubleshoot carrier rates that aren't displayed at checkout

If your connected carrier account isn't returning rates at checkout, then check the following details:

  • Your carrier account is still connected in the Settings > Shipping and delivery > Carrier accounts section.
  • Your plan includes carrier-calculated shipping.
  • If you activated UPS negotiated rates, then allow up to three business days for those rates to become available at checkout.
  • The rest of your shipping setup returns rates for the test address that you're using. Refer to Troubleshooting and testing shipping rates.
Troubleshoot rates that don't match your carrier account

Rates at checkout can differ from the rates in your carrier's own tools. Review the following causes:

  • You're comparing against the wrong rate. Your carrier's tools display both a published retail rate and your own account rate, so compare against the rate that your carrier labels as yours.
  • The shipment details differ. A rate comparison only holds when the account number, package dimensions, weight, and destination city, postal code, and country all match.
  • The service isn't supported at checkout. UPS SurePost, UPS Mail Innovations, UPS Access Point, UPS Simple Rate, and FedEx One Rate rates can't be displayed at checkout, even with carrier-calculated shipping.
The Paid By Customer is not a valid payer partner of the Mailed On Behalf Of Customer

If you get an error message saying The Paid By Customer is not a valid payer partner of the Mailed On Behalf Of Customer when you buy a Canada Post label, then the Canada Post account that's connected is a child account that doesn't have permission to make payments. A child account without payment permission can't buy labels.

To resolve this issue, ask the owner of the parent account to give the child account permission to make payments, or connect a different Canada Post account.
