I've been looking at afffiliate software trying to find a comprehensive 2 tier reporting program which sits on our own server (for link pop etc.) and not on a 3rd party. Integration with a shopping cart and merchant account would also need to be included. Any good ideas? Price is not the key issue, but ease of use, functionality, and in-depth reporting are top priorities.
I've scoured cgi-resources and a couple of other sites which have the various scripts, but nothing has jumped out.
