The basis for the order

Three-year bill was the deciding factor in Arizona. The method gives three-year bill and what the money buys 32% each and splits 36% across renewal handling, local rules match and pricing openness.

Total outlay with Arizona Registered Agent.co over three years: $297, $150 less than Mainstay Filing. An agent needed only in Arizona gains little from fifty-state coverage, so the lower yearly price decided the grade.

Every criterion and weight is listed on How we rank.
