The basis for the order
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Idaho the decisive one was charge over three years.
Over three years ID Registered Agent.org totals $297, $150 less than Mainstay Filing. A company that needs an agent only in Idaho gains little from fifty-state reach, so the lower yearly charge carried the ruling.
Each criterion and its weight appear on How we rank.
