Doing business (disambiguation)
v. carrying on the normal activities of a corporation on a regular basis or with substantial contacts-not just an occasional shipment. This is important to determine if an out-of-state corporation is "doing business" in a state so that it can be served with a complaint, is subject to certain state taxes and/or must register as a "foreign" (out-of-state) corporation operating within the state.
