The Giants (the way I call “huge” clients with structured organizations) usually have a huge amount of internal sw utilities and tools.
Web pages you can customize, teamrooms for sharing docs, customized planning tool, special tools for making presentations, even blog hosts you can use.
I noticed most of them are often unknown, misused, almost ignored by client’s teams. They probably paid for them some good consulting company who gave their best to leave a sign, so they can often be very innovative.
Learning how to make the most of them can be a real plus, keeps you insight and gives you tips for proposal when moving to a new client project.
