What we would pick in Missouri

Five weighted criteria set the order (see the method): three-year fees 33%, filings covered 26%, and then renewal terms, fit with Missouri rules and a clear state fee.

First pick

1. Mainstay Filing: best for owners who may add a state later

You pay $149 in year 1 and $149 in year 2

We start with Mainstay Filing, and the reason is simple: a $149 agent price that applies in all fifty states, so growing companies need only one provider.

Missouri Registered Agent.co is $150 lower over three years, but this provider takes more of the state paperwork off your plate, and that is what moves it up.

What your money gets you

  • A street address in the state, on file
  • Scans anything served on the company the same business day and does not charge for it
  • Scans your first three government letters each year at no cost
  • Also works for nonprofits, corporations, LPs and LLPs

What works

  • $149 yearly, with no step up
  • One price, any state

What to weigh

  • Costs you $50 more each year than Missouri Registered Agent.co
  • Report filing comes with the formation package
