Why Maine Registered Agent.co comes first

Two criteria lead Filing Verdict's method at 35% apiece: total over three years and paperwork the price handles. Renewal behavior, match to the state and up-front pricing share the other 30%, and Maine came down to total over three years.

Maine Registered Agent.co totals $297 over three years, $150 under Mainstay Filing. A company that needs an agent in Maine only gains little from fifty-state coverage, so the lower yearly price decided it.

The full list of criteria and weights is on How we rank.
