For most of them, you don't need a business license if you are just having the checks payable in your name.Do you need a business license to run a store on one of the fulfillment services?
I'm not sure if this is 2 separate questions or 1 questionWhat if you have your own domain name that links into one of those stores? I assume that under any circumstance you would have to trademark your name?
But you don't *have* to trademark your name to do business with that name. You may want to do a trademark search to make sure the name you want to use is not already trademarked.
Unfortunately, this won't give you any copyright protection whatsoever.Trademarking can be a bit expensive but to cover your butt for the first few months you can mail your designs to yourself, then file em away without opening the envelope.
