What decided the order
In Iowa, filings in the price decided the order. If you're curious about the weights, three-year cost is 29%, filings in the price is 29% and renewal price, state fit and up-front totals share 42%.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over Iowa Registered Agent.co.
