The two matching signals plus a log is the part I was missing. Case by case is exactly where this goes wrong, because whoever is on support that day ends up being the policy. The other-admin check for team accounts is a good one too, cheap and hard to fake. I'm going to write the checklist down before the next one of these lands.
Good catch on the proration, that's the kind of leftover that creates the next confused email. I hadn't thought about the cancel step leaving a credit or small invoice behind. When you cancel the extra subscription, do you also refund the duplicate charge in the same sitting, or wait to see what the final invoice looks like first?
