The carrier DHL eCommercewhich is available to USA Shipstation accounts only should be made available to UK accounts.
This would increase UK customers - many other companies which would be interested in Shipstation if they carry this option. Many competitors to Shipstation do offer this to UK accounts. It becomes difficult to split and manually process some orders via CSV upload
I have spoken with the carrier who are hoping to see this happen.
I'm aware of this ideas post requesting the same for Canadian shipstation accounts in 2016. This was marked as Started 11-30-202110:44 AM
