Just to use an example fresh in my mind... we're a Google Apps customer and bought a bunch of Lucidchart licenses to help wean people off Visio. One of the things Lucidchart does that, if we had known about it beforehand, we'd have written into our terms, is that they refuse to delete accounts even after a person's Google account is deleted, so we end up paying for licenses for terminated employees unless we physically add Lucidchart as a checklist item in our termination process, and then pay a guy to go do the needful and de-allocate it. Lucidchart is cheap by comparison to lots of things, but managing licenses is a pita (and they are by no means the only offender).
