We are in the process of changing over to SB1 and are looking at what other companies have done with regard to shipping and credit card processing. We are a high volume shipper ( in excess of 1200 pcs per day) and credit card merchant( in excess of 500 transactions per day). We like are current Integration Partner, however, everyone knows that one company cannot have all the available options.
