I want to offer a founding member pricing. Can I offer $15 a month and then change the plan to a 2-tier plan?
Will the people subscribed to a $ 15-a-month plan still work? Thanks.
You can make more than one paid tier, absolutely!
If you already have one paid tier with subscribers, you can add an additional tier at any time. You cannot move people to the new tier. Existing subscribers will stay on the plan they are currently subscribed to. The new tier will be empty when you create it (no subscribers).
Additionally, you cannot make one paid tier that is a paid subscription and then another tier that is a one-time payment.
Hope that helps. Let me know if you have more questions.
