Previously used and fired the Multi-Carrier plugin. It has serious issues, and the devs refuse to address them. I had setup a clean staging site and their issues remained. It is an expensive, bloated plugin with problems. That is why we started using Live Rates (as we discussed on the phone some time ago).

The WooCommerce Shipment Tracking plugin is active to return tracking numbers from ShipStation to the site(s). Neither this or AST offer rate calculations.

Live Rates seems to forget, in this example, that multiple boxes exist, only calculating for one. These results came from “Custom Box” selected in the settings. I’ve reverted to ‘One Package’ and ‘Stacked Vertically’ and cleared the API cache for this account to track these calculations. Previously, that setting also caused issues with rate accuracy.
