If you are talking about a business license, Here is a general rule from my state licensing board. A business offering a tangible product (basically a solid object) for sale has to get a license. Further, anything done by said business to generate profit requires the business to have a license. IE., putting an ad in the newspaper.
It depends on the type of service you are offering also. In my state, a writer does not have to have a business license. But a company that runs a carpet cleaning service may be required to get a local license.
