Its ease of use & great shipping discounts should be enough but the way it expedites our shipping is amazing. Our shopping cart offers a similar service built-in that we could use for free but we won't jump ship. Everyone here who uses it has different things they like and I am addicted to them all. ShipStation's robust features make order fulfillment a positive experience instead of the nightmare it was before we discovered it. Review collected by and hosted on G2.com.
What annoys us the most is the lack of integration with HS code lookup for international shipments. This is a no-brainer, especially considering that DHL, UPS & FedEx manage to do it. Occasionally it slogs out while processing. This is especially problematic when we get down to the wire before out cutoff time. We also seem to have difficulty using more than one postage service which limits our ability to take advantage of certain rate discounts. Review collected by and hosted on G2.com.
