My last gig forced us to use Asana for ticketing (!!!). It's meant as a Basecamp-like tool but I'm not sure if it delivers on that either.
Currently we use Confluence for documentation, which, like many other Atlassian products, is lacking notable features compared to cheaper competitors. Other than that, we're great: Exchange, Slack, Github (including issues), etc
Google for Business or w/e would be great, but there is no way a company this size is gonna do that.
