Why we ordered them this way
In Pennsylvania, filings in the price 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%.
Mainstay's plan does more: it scans papers served on the company the same business day, free, and the price is the same in all fifty states, with three government letters a year scanned at no charge. Pennsylvania Registered Agent.co costs less, so it's a close race.

What Pennsylvania says about the registered agent (via Pennsylvania Secretary of State)
Pennsylvania requires a registered office (a Pennsylvania street address or a Commercial Registered Office Provider), not an agent. The address has to be an actual street address or rural route box number in Pennsylvania. A P.O. box alone is not accepted. The law: 15 Pa.C.S. § 8825.
The Pennsylvania annual report: when and how much
Here's the schedule: the annual report is due every year in Pennsylvania, by September 30. It costs $7. Reminders from the state go to your registered agent.
Your questions about Pennsylvania registered agents
Do I really need a registered agent for a Pennsylvania LLC?
Pennsylvania requires a registered office (a Pennsylvania street address or a Commercial Registered Office Provider), not an agent.
What do Pennsylvania 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?

When do I have to send in the Pennsylvania annual report?
Mark September 30 on your calendar. The state's charge is $7.
