Questions about going national
What if my LLC operates in several states?
One of them does. Mainstay Filing is priced identically in all fifty states, and the other two are single-state.
The benefit shows up when your LLC outgrows its first state.
Why include local companies on a national list?
For an LLC that only needs one state, local plans can cost less. North Dakota Registered Agent.co is the pick for North Dakota businesses; LA Registered Agent.org for Louisiana businesses.
What put the first pick on top?
Reach settles it: one service covers every state, and the others do not.
The two biggest weights are what three years cost (34%) and how much work the price handles (28%); three smaller criteria break ties. How the ranking works
