Hello, the renew link can be improved in the following ways:
1) adding an explication tooltip on "renew" icon shown in the module.
2) Also you could add the following feature: option, in payplans settings, that admin can enable or not to allow the renew option for the same plan or another one belonging to the same group of plan.
In alternative to point n.2 you could create a renew app where admin can choose the plan interested and to which plan(s) user can renew.
Please this system have to work not only to renew a plan active and subscribed but also when user doesn't have any plan active because it already expired.
