I also work with basically every Amazon selling platform globally: Vendor Central (Direct PO) in the US and EU and Seller Central in the US, CA, MX, UK, DE, FR, IT, ES, TR, PL, NL, JP, AU, and SG.

The software is (generally) not the issue. The software is great. The service is great. FBA can be a game changer in many regions.

The real problem with the Amazon, from a seller/brand/manufacture perspective is support. If you get banned—if there is a hiccup, or if there is a problem of any kind—it is a nightmare (or straight up impossible) to resolve.

I don't really want to own the software. I want to talk to a human when something goes wrong. I want to talk to someone who will ban a seller infringing on my trademarks. I want to talk to someone who will give me control of my listings when someone else hijacks them.

Amazon is, for better or worse, where the customers are. I have a good product and I don't have to pay for advertising. I don't want to have to pay for advertising to get people to go somewhere else. I just want to be able to talk to a human on occasion to resolve issues. I do millions of dollars of business every year with Amazon and reaching a human—let alone a human who can actually do something—is the most frustrating part of Amazon.
