2 years ago Good question. No, ShipStation doesn't serve as a checkout shipping options calculator. It's primarily used to manage order fulfillment (i.e., shipping labels) after orders have been placed. I'd recommend checking out Postie by Verbb.
Will this plugin actually pass available shipping provider options/costs from ShipStation to the customer during checkout, or do I have to maintain those options manually in Craft Commerce? Wasn't seeing this anywhere in the features or documentation.
