Successfully Created a Shipping Method

After you create your shipping method(s), it will appear as seen below. To manage the newly created method(s):

  • Click the Method Name to edit (opens up the settings/form as seen above).
  • Click Trash Can to delete a method

NOTE: InkSoft utilizes real-time rates that we negotiated on behalf of our customers. These rates are automatically applied to your account once you have successfully configured a real-time rate integration. There are no other actions needed to be taken to get the real-time rate pricing.

Additionally, FIRST CLASS mail has a 13 oz weight limit. This option will not display if the cart has items that exceed that value. This method should be used in conjunction with Priority Mail or another service, otherwise, your customer may not have any shipping options to choose from. 

NOTE: Something to keep in mind is that when you get a full ShipStation account, you will also get a account. This will make the integration even easier if you use that service.
