As a client for the last 2 years with 4 brands transitioned from vendor central to seller central by SellerSlice, I would gladly recommend their services (and have) to anyone that wants to maximize their business on amazon.com. I started with little to no knowledge of the different selling formats available on Amazon and now, thanks to the SellerSlice team, feel link i can explain the differences to anybody that asks. They held my hand through the entire process ad allowed me to ask hundreds of less than smart questions with biblical-level patience and understanding. while the transition was at times tedious and difficult, it has paid off in many ways, not the least of which are increased sales, increased margins and much more control over map policies.
