All the apps SSO against my identity provider so switching between them is pretty seamless, and billing is unified: instead of a bunch of independent Stripe charges, one subscription can grant access to multiple applications. One app is $5/month and four or more are $8/month, billed as a single charge, so Stripe's fixed 30¢ fee is paid once rather than four times.
I'm going through the "one (to|two|too) many" problem right now: picking the next app and working out how to present a growing list of products without the site turning into a junk drawer. Curious how others have handled that.
