jwarren: I see that Method uses Method CRM for its own internal use.
We definitely do!
jwarren: I am trying to vaiod reinventin gthe wheel and looking for some valuable feedback from Method?
Our portal screens are customized but you can definitely achieve similar functionality if desired. The customization would be a little involved for a subscription billing model so I highly recommend you speak with a Method Solution Provider or book a session with a consultant on staff.
If you're looking to build this on your own, we can provide a little support via the forms but you may require more help than we can offer here. Your best best is to start by making a copy of the current portal pages and dig into how these work.
With regards to PCI comliance, storing credit card numbers is something we strongly discourage. Consider credit card tokenization if you want to store the details of a customers credit card for recurring billing. Speaking with a solution provider or a consultant in this regard will really help you design the best system to be able to offer recurring billing.
