Great Question. Depending on what type of business or services you are planning on having. There are many requirments depending on the state and city that you operate your business in. This also depends on the product, mostly and or services. Do you plan from working from home, or a brick and moter a building is called brick and morter, as business refreces to. Or an online in the air type business? Many variables. You must have good operating capital, and help usualy from Small Business Admin. or S.C.O.R.E. if you google business start for your state you will find a list of forms and check off list of all the things you will need to do. Good luck. I hope you start a business.
