I have been using Blackthorne Pro since June 2005 as one of the original testers. It has made my life and entire operation run extremely smooth. I have had very few bugs with the software and those have been fixed.
The import from eBay is a smart import of your items, listings and sales.
There is a significant learning curve with Blackthorne and you cannot just jump in and go at full speed. You need to learn how to use it process by process. That is what I did and now I am able to help others solve their problems with Blackthorne.
