There are two ways:
1) the first way requires ShopSite Pro, and custom programming via the Order API feature. All order data can be passed as name=value pairs to your own custom script, which can then do whatever you code it to do with that data, such as write it to your own database or into an XML file. Your custom script could even email the XML file to your order fulfillment center immediately after the order is placed, if that is something that works for them.
2) the second way requires ShopSite Manager or Pro. The ShopSite orders can be downloaded in an XML format in these product levels, and you can even write a program to automate the download of the XML data (see
http://www.shopsite.com/help/10.0/en-US ... -auto.html for info on the URL parameters that an application can use to trigger the download). You would then have to have a program that takes that order data in the ShopSite XML format and converts it to your order fulfillment center's XML format.
