We always suggest that you register your company as a business entity. This provides some tax benefits (talk to your CPA or business attorney about how), and positions you as a serious company in the eyes of your customers.
You may also discuss with your insurance company about any need for additional insurance, given that you are starting a business from home.
We have listed resources where you can find these services on your own. However, we encourage you to discuss this with your CPA or Attorney to make sure everything is done correctly.
