Folks! I am looking for a solution to be able to manage my dad's massive inventory of books in his warehouse. We've been selling on Amazon, Flipkart and a few other sales channels. The problem is the SKUs are different on the marketplaces. So if there is a tool which can just map the same products from the multiple channels, it would be great. What would be ideal solution for this? Or if anyone is up for developing something for it?
