Who’s Selling My Products on Amazon?

Hi,

I’m new to Amazon, but I’ve already registered my brand and had it verified by Amazon.

I have almost 200 skus. Due to distribution history with partners in USA and Canada, some of my skus have already been listed on Amazon by them before. Some of them do not work with my products now, some of them work under names that are not the same as their official company name, etc.

So I would like to know if there is a solution to track who is selling my products on Amazon. But I might need some software because checking 200 skus one by one is pretty… tiring.

Could you please help me and tell me which software or service offers this possibility?

Thanks a lot!
