We use this software for all of our international shipping needs which includes importing into ERP systems (Mintz) as well has exporting out to FedEx or other carriers/shippers in different countries via their API's that are available through their website! The interface is very user friendly when setting up new accounts especially if you have previous experience using an Air Freight system like DHL Global Mail / APOEX etc..
This makes it easy since we don't need any training from them because they already provide online tutorials so no additional help needed once set ups correctly! I do dislike how some things work sometimes such being able to copy paste information between emails but its not something majorly bad just minor inconvenience at times.
