Membership with payment plan

I want to offer a payment plan for my membership site.

It will be 3 payments of $251. The person will then have lifetime membership to the materials.

I just want to clarify how this needs to be set up.

Below is what I think it should be
I need to make sure that this will automatically take the payments each installment.

Level 1
Indefinite
14 days ( this is how long in between I want the next payment to be taken out on)
Price - $251

Level 2
Indefinite
14 days ( this is how long in between I want the next payment to be taken out on)
Price - $251

Level 3
Indefinite
14 days ( this is how long in between I want the next payment to be taken out on)
Price - $251

Level 4
Indefinite
14 days ( this is how long in between I want the next payment to be taken out on)
Price - $251

This member site is being run launch based meaning every member gets access to the content at the same time. I was planning on just giving access manually to that group each week.
SO the levels set up above except for the first will not actually contain any levels.
It's purely to make the payment work.

Have I understood this correctly? Please correct me if I am wrong. :slight_smile:
