The most important feature for me are all available reports as well an overview over our current status with regard to shipments/invoices etc.. I have not yet found any features i dislike so far but would like more customisation options than what's currently offered (e g.: no ability at this time per say). We use it since about 1 year now - during which we had many problems before getting used to its functionality especially regarding shipment tracking or invoicing / billing issues- however they were resolved very fast by their support team!
