Yeah, not to pile on... but I have to believe that pricing, at least on the lower end might be out of whack with what I still think is your target clientele - a group that likely all have some inhouse development resources. Faced with the reality that at least some integration is likely to be needed, I'm not sure Chargify would even get on my radar given the new pricing structure. To me, I always thought Chargify was "get full fledged service up and running quick, by the time we're rolling along, why mess with a good thing".
The PCI compliance bit is somewhat misleading, as at least for integrated solutions, just because Chargify is PCI compliant, doesn't let us off the hook. So if we have to be PCI compliant(integrated solution), we are basically paying for dunning management? I'm being facetious but hopefully that illustrates what others are probably thinking. My approach will now be, build out simple customer management system, tie into a payment gateway and build out related services as site/business grows.
Sucks for me... I spent a decent amount of time integrating/understanding how Chargify works and now I realize that Chargify is simply not an option(trial users were actually my biggest draw).
Anyway, you have guys have built a great service. Wish you the best.
