I'm definitely getting screwed over by this. I've hosted close friend's and family's email for a decade now on an old G Apps instance. We only ever used it for email on a custom domain. It was most useful because I could reset passwords for them if they forgot it. Now I'm going to have to figure out what to do. Microsoft's Family offering is way better (not saying much considering Google doesn't have one). Right now…
And my advice: If you go that way, charge them automatically by CC every month and add a 30% markup to cover inevitable extra costs like footing the bill when someone cancels unexpectedly.
