How the lines were rated
The rating method counts cost over years one to three and inclusions per price at 27% each and splits 46% among renewal price and terms, fit with state rules and price clarity. For Missouri, cost over years one to three was the deciding line.
Missouri Registered Agent.co sums to $297 across three years, $150 below Mainstay Filing. For a company that needs an agent in Missouri only, fifty-state coverage adds little, so the lower yearly amount decided the rating.
