Besides being a single point of failure, we tried to switch to ChargeBee and found them to be pretty lacking (to put it mildly). The platform looks nice and has lots of options, but under the hood things seem pretty fragile. Horrible docs, random 500 errors that weren't showing on the status page (and support ignored until more customers reported it), our Stripe gateway disconnected and the system still appeared to be working (partly, partly failing) with no alerts, plus lots of other odd behaviour. To be fair, all of this was on the test system, but we didn't feel confident to go live so we put the migration on hold. YMMV of course.
