I'm not sure if this is feasible or not, but I'd love to read an overview of how you are handling the different plans scenario (previous plans setup vs new pay as you go setup) on a technical level. It'd be helpful for any SaaS owners who want to one day do something similar and as far as I know, no one has ever documented this process.
