Only Display Qualified Shipping Methods that Meet Promised Delivery Guarantee
Especially when we ship orders for Premium 2 Day, or Seller Fulfilled Prime on Amazon (but also when our customers upgrade shipping on our storefront), it would be incredibly helpful for Shipstation to only display qualified shipping methods that will meet the delivery guarantee.
If you use the Buy Shipping Services in Seller Central, it already filters out methods that don't meet the guarantee. For example, if we are shipping from Indiana to Illinois, ground shipping is eligible, which saves us from paying extra for 2 Day Express. After all, the customer is buying a delivery time frame and not a specific carrier method.
Within Shipstation, even when using the Amazon store connectivity for the Buy Shipping API, employees have to test each method to see if it qualifies.
When deployed for every connected store, this will not only eliminate human error, but it will also translate to cost savings for your connected merchants (great selling points for ShipStation to gain more clients).
