We are in desperate need of the FedEx Collect Ground billing option. We have thousands of FedEx Office (Kinko's) locations that we ship to daily and they require that billing option for all incoming shipments. My boss wants us to leave Shipstation for ShipRush Web that has that option and their service is free. Many of us prefer so many more of the features, interface and speed of Shipstation, but not sure how much longer I can delay that. Please advise.
