If you want to use multiple shipping carriers to ship parcels, this is easily possible with our shipping adapters. We recommend that you assign exactly one product of a shipping carrier to a shipping method in a clear, unambiguous way, as described here.
Example: If you have created a shipping method called UPS Standard Shipping in your Shopware backend, only one UPS product should be assigned to it in the UPS Shipping tab. In the DHL Shipping tab, on the other hand, No assignment should be selected.
This clear assignment allows our plugins to automatically create the correct shipping labels for the desired shipping carrier for every order. This works both when using the Add shipping label icon in the order list and in batch processing mode, as well as when working with Pickware WMS.
