Hello I am looking for a big Zen Cart add on. It must download all orders into zencart and when we mark the item as payment received or dispatched it must automatically do the same on eBay. It must also have a built in FULL accounting programme which downloads eBay fees & paypal fees as well as have places for me to input stock & other costs. Must also have the ability to upload listings to eBay using Zen Cart Products. Please leave a qoute.
