What are the benefits and drawbacks of starting an indy publishing company for my books? Preferably just a DBA I live in the county so I'm not required to register. (Free) In CA an LLC cost $800 a year just to have it. I do use a UPS mailing service to avoid putting my home address out there. And do you need a business bank account to be paid by Amazon if you are listed as the owner? I have ISBN's in my name, would i be able to transfer those to my publishing company or would I be required to purchase more?
