Review of TeamSupport
The account based view makes it easier to understand a business customer as a whole, and that is a useful fit for support work where several people may be involved; onboarding takes attention, though, before the team can use that view consistently.
Reporting through the analytics offering gives managers a clearer way to review product usage and customer needs, but I would want the initial setup explained plainly, because a small operations team cannot spend much time sorting out how each part is meant to work.
The customer success tools add practical value for long term relationships, and I can see the benefit for B2B accounts; adoption still depends on staff following the same account details, so I would plan a careful introduction rather than expect everyone to pick it up at once.
