I want to add a courier company to the dropdown list where you choose your shipping carrier when fulfilling the shipment. I don't use any of the carriers in that list and have to use the "other" option. How can I add the name of the courier company we use to this list?
Have you tried https://YOURSTORE.myshopify.com/admin/settings/shipping/accounts_and_integrations where you can add Carriers and Fulfillment?
It seems like Shopify won't add a little-known carrier called Parcelforce UK to the carrier dropdown list. Have contacted support many times and they say that Parcelforce should be added and they will pass it on to the developer team. But then nothing. Also it seems like the list of carriers can't be edited in any way. Bemusing that they can't or won't add Parcelforce.
