Behind the order

The desk's method puts 33% on spend over three years and 33% on work the price removes, and 34% across what renewal looks like, fit with the state and plain price display. For Iowa, work the price removes did the deciding.

Iowa wants a report every other year and charges $30. Mainstay's price covers that filing and Iowa Registered Agent.co's does not, and that outweighed Iowa Registered Agent.co's lower three-year cost.
