The best option for this is to have the 2 different membership types and 2 different recurring service types. This is to keep the deferred revenue and revenue recognition from braking that chain. You cannot have a fixed duration and a ongoing duration on the same membership.
1 for Annual billing that is Ongoing. Will require a sales task and billing task for the auto-billing for next billing date. The recurring service duration type set to Continuous.
1 for Fixed 12 Months with a renewal. These memberships will also be on the Follow Up tab for expiring memberships to be called on to renew. The recurring service type duration type set to # of Total Visits.
For the upcoming options I would isolate those customers on Follow Up and create an Estimate with those options.
