What I would recommend is to take a very "pluggable" approach. Create methods which access data (inventory, etc), and simply allow people to over-ride those as necessary to integrate. As for serious accounting data, this is a good use for XML.

As was already mentioned, an API should be defined for this purpose. Then the developer is free to implement this however is necessary. As for protocols... is there any existing Python modules for EDI? - Josh Zeidner _______________________________________________________________ Get Free Email and Do More On The Web.
