I can speak about onboarding and knowledge transfer from the viewpoint of our clients. Usually they give us access to their past tickets and we have an hour long conversation where we ask a million tailored questions. Then clients put us in a sandbox to play where we can't hurt anyone. To fill knowledge and capability gaps, our ops managers pose questions to in-house teams, usually over Slack, but it can be anything. Once everyone is comfortable, they let us out into the world. :)

On the back end, I wish I could brag a little about this, but it is our "secret sauce" so I'm just going to have to say it's proprietary and I believe the beginning of something great.

To directly answer your first question regarding edge cases, it's simple: we don't do them, opting instead to let your in-house team do the complex edge cases. Over time though, we inevitably end up doing some of them as we find commonalities across clients (shipping exceptions, insurance disputes, etc).
