I need the following features which I will list now briefly below, but I may need additional features that the above software's do not have – will discuss this further when we speak one on one. Automating the uploading of eBay listings - So, I should be able to choose which products I want to sell from the Amazon website and once put into the system, the product will be automatically uploaded onto my eBay account. Pricing of eBay listings – So, if the price on Amazon changes, the eBay listing should automatically update to reflect the price change. Monitor supplier prices - I should be able to set a profit margin % and if a competitor on eBay reduces their price for the product, my listing should automatically lower in price as long as it still meets the minimum profit margin % I set. Set availability rules – Consider items for example on pre order, backorder, minimum order quantity, or to be out of stock. Set to increase price, modify handling time, or hard delist corresponding listings. Maybe some types of dashboard or area where a user can monitor pricing updates in real-time, configure pricing rules, set exceptions for individual listings etc. Allow the option to automatically increase quantity after sales to hold to a fix level. Auto ordering – So, allowing an order to be made automatically on the supplier website (Amazon) when an order is made on the selling website (eBay).
