I am planning on creating a website where I will be promoting a product to sell for some other website, do I need a tax id and a business license? I mean, since I am not using any merchant account, just promoting a product from another website.

I recently purchased the licenses to 6 online stores, fully equipped with credit card processors, shopping carts, and merchant accounts. I have already found a product I wish to sell using the first of my 6 websites. However, the distributor needs an EIN before I enter into business with them. What all do I need to get to conduct business legally from my home over the internet? I will be particpating mostly in dropshipping and I am located in Michigan. Is it necessary to form a business and register a DBA?

I wanted to make a google merchant account for my artwork website, but was not sure if i had to have a legit business license or not.

Some dealer only auto auctions I attend state that “Mexican merchant” is a valid form of dealer’s license. How does a person obtain a valid Mexican merchant license and how does the auction house verify the validity of the license? This sounds like a sham to me. Thanks for any info.
