we are looking for a google analytics-like product but we would like to have the ability to push our own data and analyze them. For instance, we work a lot with affiliates where a visitors visit our site, find some product, visit the owner's website and buy it (that's kind of our funnel here).
We can measure everything within our website, but for those external sales, we get a weekly report. We are looking to import (through some web service or something) those reports into the X analytics product and visualize the complete funnel, conversion rates etc.
Is there such a tool in the market?
