Ecomdash integrates with your shipping carriers such as Endicia, FedEx, UPS, DHL and STAMPS.com to be able to streamline your shipping label generation. To start shipping out of ecomdash you will want to go to Administration, and then Shippers and add your shipping integrations.
You will also want to make sure you have turned on auto import of your sales orders. This feature is located within Administration, and then storefronts. You will see within each integration page detail a check box to turn on auto import of orders.
