I need Software required for Drop shipping from one marketplace to another- The two market places will be Amazon to eBay – (but more market places maybe added can further discuss this.) I want the software to function similar to Priceyak, Trackazon, and Price Spectre etc. 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 pricing of eBay listings – So to automatically update the listing based on the supply & availability of suppliers & competitors. Monitor supplier prices and automatically revise price on eBay listing according to user pricing formula. Set availability rules – Consider items for example on pre order, backorder, minimum order quantity, & more 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 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) – Will include details of what needs to be automated on this when we speak.
