You may want to just find someone who has been selling on amazon for years and have them handle your amazon account. The going rate for that is usually 10% of your net sales. so whatever amazon pays you out you pay 10% to an amazon pro seller. This is actually what I do for a living. I am not soliciting to you to sell your products I am just telling you what I do for a living. I’ve sold on Amazon since the beginning and I can tell you that it is a very complex marketplace. Amazon is constantly changing things and trying new things all the time. You almost need a Phd to sell on amazon these days. There has been an influx of chinese sellers over last few years, not too mention amazon selling things themselves through vendor central. Vendor Central has the products you see that say “shipped and sold by amazon” this is kind of what your talking about. On vendor central, which can be a total nightmare I might add, you allegedly just ship to amazon and they handle everything. However turning a profit and getting paid in a timely manner on vc can be hell. VC is invite only but many accomplished sellers have a vc account along with seller as some products are better suited for vc.

Just find someone that already knows all the ins and out of amazon and have them do it for you. It offers a selling platform that generates sales better than any other platform in US bar none. Anyone that tells you different is just trying to scare you off as new sellers are not always welcomed on this cut throat platform that can suck the life out of you.
