Why Mainstay Filing is placed first
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Iowa the decisive one was work taken off the founder.
Mainstay's plan reaches further: papers served on the company are scanned within the same business day at no cost, the price is identical across all fifty states, and three government letters a year are scanned free. IA Registered Agent.org charges less, so the margin is narrow.
Each criterion and its weight appear on How we rank.
