Why this order

What made the call in Iowa was launch paperwork handled. The grading method sets cost to launch and stay at 26%, launch paperwork handled at 26% and renewal behavior, state match and price transparency at 48% combined.

Adding a second state means dealing with two states, and one provider at one price in both earned the stronger coverage grade, ahead of Iowa Registered Agent.co.

Every criterion and weight is listed on How we rank.
