Why this order for New Mexico
Filings covered by the price gave Mainstay Filing the lead. It makes up 29% of the order, and tracked three-year cost, renewal movement, crossover year and price visibility cover the remainder.
A tight call: there is nothing to bundle, yet filing and agent for one price still came first.
Put the EIN application into the sum and the totals cross at year 2, when Mainstay Filing passes NM Registered Agent.org.
