What we need is basically a go between our backend system and ebay. Here are our needs in order of importance:
(1) Bulk uploading our inventory to ebay
a. Ability to bulk list, edit, and end ebay items.
(2) A interface to view current items we listed on ebay and with the ability to manipulate items
(3) A way to map the ebay categories to our website categories.
(4) We want to be able to have customer who purchased items on ebay checkout via our website. To do that we need to gather transaction data for the given sale made and pull it back to our site given a ebay item number and ebay id.
