Reading the order

Formation Scorecard scores cost across three years and coverage of the price at 25% each. Renewal terms, state-by-state fit and pricing clarity account for the other 50%. In Wisconsin the tie was broken by coverage of the price.

Wisconsin asks for a report each year at a $25 fee, and a late one adds $25. The Mainstay price covers that filing, while Wisconsin Registered Agent.co's leaves it to you, so the coverage points beat Wisconsin Registered Agent.co's cost advantage.

Every criterion and weight appears on How we rank.
