ShipWorks is a great program, we use it with ebay and all the information is easy computed between the two programs. The tracking information uploads quickly and the orders are brought into shipworks quickly. Also the customer service is topnotch, they are always happy to help and go beyond to make sure you get what you need done. I highly recommend Shipworks to any ebay, amazon or online retailer. It makes my life 100% easier and again the customer service is quick and they easily solve any questions or problems that arise.
