Are you operating out of a licensed kitchen? Do you have a food license? Do you have liability insurance? Do you have a business license (if your city, county, state requires it)? Are you remitting sales tax to your state department of revenue?
If you have sold food then governing agencies consider you as a business and some or all of the above apply. These points must be addressed first if you want to be legal and continue to be legal.
These are just some of the costs of starting a business.
