What do I owe after registering?
No yearly report applies.
What put number one on top?
The deciding factor is how much work the price handles (28% of the weight), where Mainstay Filing is strongest.
Five criteria set the order: what three years cost (34%), how much work the price handles (28%), prices spelled out (16%), renewal terms (12%) and reach beyond one state (10%).
The home state needs an agent as well, and one account for both is simpler.
