The way it integrates with my other tools (eBay) so I can see listings as they come up via eBay API - notifying me when an item has new bids or updates are made. That's about all you should need from one software tool. Sometimes things don't work properly together (like adding items in both). If that happens then contact their customer support team and explain what happened & why etc., try them out first but this isn’t too bad! Using other companies data sources such as Ebay. To know which ones have sold best before listing these through SellMyListingPro allows us better information to use whilst advertising online/offline without having people spamming our emails asking where we're getting goods form when its already known. I like how easy it was set up with my existing CRM system as well all fields are customizable if needed! The training provided by their team has been very helpful too!! There really isn't anything i dislike about this product other than there may need more customization features available (or maybe they could add some new ones). This software does exactly what we've used before but better & easier.
