What settled it

Mainstay Filing did better than Oklahoma Registered Agent.co on upkeep the price covers, a 31% factor.

A foreign LLC already lives in two states, so a provider covering both came first.

What Oklahoma charges you to register a foreign LLC and what it requires

Out-of-state LLCs, yours included, deliver the Application for Registration (Foreign Limited Liability Company) (SOS Form 0081) to the Oklahoma Secretary of State, Business Filing Department with $300. Add certificate of good standing, existence or fact issued inside 60 days.

Operating without registering may mean no standing to sue before Oklahoma courts (18 O.S. 2048(A)).
