You'll need 3 plans to do that if you want different price and duration options. There's no way to add additional duration options to a single plan at this time, but is something we're looking into. Additional pricing options is possible using CBSubs Promotions and creating promotions that apply to your plans automatically. If you already have the 3 plans though you could just adjust the price directly and not need promotions. You'd need to clarify further the plan setup you're wanting for me to suggest anything more specific.

Thanks

You might consider configuring an automatic discount that applies based on the subscription date of the existing plan.
You might need to use a Query field to set this up.

Can you tell me how the membership plans are setup on this site. I just looked and it appears that there are 3 plan options for Professional. Is that done via parent plans ?

They're 3 separate plans. We're using CSS to stack them so it looks like a price/duration selector, but it's actually just 3 plans.
