How the grades were set

Biz Formation Report grades three-year bill and what the money buys at 32% each, leaving 36% for renewal handling, local rules match and pricing openness. In Iowa, three-year bill settled the order.

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

Every criterion and weight is listed on How we rank.
