Looks like you are both looking for a solution to help integrate Magento and Amazon so that updating data is seamless and instant.
Using the nChannel connector for Amazon web sites you can quickly and easily integrate and connect your Amazon web store to a variety of eCommerce, POS, ERP and accounting systems. For existing Amazon sites, once downloaded, our Amazon connector starts copying your customer, item, sales and supplier data to the nchannel platform. Simply add additional connectors for the other channel systems you use to begin exchanging data between Amazon and any other channel.
If you are new to Amazon and haven’t populated your site yet, you can use nChannel to push item and inventory data to it from your POS, other eCommerce, ERP or accounting system.
