The filing needs no proof from your home state.
What do I do after the LLC registers?
Next you file the business privilege tax return, which costs nothing.

Quick answers
What about the state where I formed the LLC?
Yes. Your home state keeps its own agent rule, and Mainstay Filing can serve both states from one account.
How do the three-year costs compare?
Mainstay Filing adds up to $497, AL Registered Agent.org adds up to $397, Alabama Registered Agent.co adds up to $397, with state fees on top.
Are the fees official?
Official Alabama sources back the state side and company pricing backs the service side, all dated.
Do I need to hire a service?
No. A service charges for labor and the agent role, not for anything the state demands.
Will a service file the registration for me?
They do, so the only cost that changes is the service fee.
Which foreign registration service should I start with in Alabama?
Mainstay Filing, because you pay $199 plus Alabama's fee, get a free first registered agent year and then pay $149 a year. Then AL Registered Agent.org and Alabama Registered Agent.co.
