We are using channel sale to manage our inventory in multiple marketplaces. The reporting is extremely detailed and allows us to track our spend within each marketplace. It's very easy to use and set up once we understood how it works. Reporting isn't as intuitive. Some reports require double clicking or scrolling down the page which could be better. If you have the right people in place this can be easily sorted out but if not then make sure you hire your team well or consider other tools like Xero. Manage our vendor's inventory on multiple eCommerce platforms. This helps us keep a close eye on our spend in real time.
