If cubic rates are enabled on your Stamps.com or Endicia account, do the following to receive cubic rates in ShipStation:
- Choose a domestic Priority service
- Choose a package type of package*
- Enter the package's weight & dimensions.
ShipStation will use the Cubic rate whenever it's cheaper than the Priority rate!
If you have an Express1 account, instead use the package type of Cubic* to receive the correct rates.
*Stamps.com and Endicia require the package type of Package to return Cubic rates. Express1 requires the package type of Cubic to return Cubic rates. Using the Cubic package type for Stamps.com or Endicia will result in an error when you attempt to get a rate.
Keep in mind, cubic rates are subject to change periodically. Please reach out to your provider if you'd like a full breakdown of the exact rates per package volume.
