We need to sync our inventory between our site (Magento CE) and the BikeExchange.com.au site. Note that BikeExchange works in a similar fashion to eBay Bikeexchange has a api. I have attached the doc file. Currently all products we have available are in our Magento Currently we are also listing and selling on the BikeExchange site All items listed on BikeExchange are manually added. Not all items are there. If an item sells on BikeExchange we update our Magento site manually If an item sells on our Magento site we update BikeExchange manually We want to avoid this manual work so that both sites are in sync PS: If you know how to do, please write how to do more details. I will select candidate according to cover letter.
