At UsabilityHub we (fortunately) circumvented their "free" user count by never sending them to Chargify in the first place. If we did, we'd be now getting billed $1000 a month. We did this because when we switch to chargify a couple of months ago we had over 8000 users and didn't want to migrate them all to Chargify. We'd be shutting up shop right now if we had. I'm doubly lucky as I was about to start migrating users to do "one off" billing using Chargify. Given that every one of those would now count towards our monthly fee we'll be using a different service for "one off" purchases.
