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. Also the above software will very possibly need updates, tweaks and new features in future so will be further work there for whoever creates the software for me. Would prefer developers who have experience in making similar to the above already or/and be knowledgeable in these areas and also want to be able to communicate with you regularly via (Removed by Freelancer.com admin) etc.
