Why we ordered them this way
In Oklahoma, three-year cost 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%.
OK Registered Agent.org comes to $297 over three years, which is $150 less than Mainstay Filing. If you only need an agent in Oklahoma, fifty-state reach doesn't help much, so the lower yearly price won.

What Oklahoma says about the registered agent (via Oklahoma Secretary of State)
Every LLC must name a registered agent with an in-state street address. The address has to be a street address in Oklahoma, at a business office that is open during regular business hours. P.O. boxes are not accepted. The law: 18 O.S. § 2010.
The Oklahoma annual certificate: when and how much
Here's the schedule: the annual certificate is due every year in Oklahoma, by anniversary date of the filing of the Articles of Organization. It costs $25. Reminders from the state go to your registered agent.
Your questions about Oklahoma registered agents
Do I really need a registered agent for an Oklahoma LLC?
You do. Oklahoma won't accept an LLC without a registered agent who has a street address in the state, and that name goes on the public record.
What do Oklahoma registered agents usually cost per year?
Plan on $99 to $149 a year, and each service keeps its price when you renew.
Can I be my own registered agent?
Sometimes, if you meet the state's rules. The LLC itself, an Oklahoma resident, or a corporation, LLC or partnership formed in Oklahoma or qualified there.
When do I have to send in the Oklahoma annual certificate?
Mark anniversary date of the filing of the Articles of Organization on your calendar. The state's charge is $25.
