I believe I remember reading about Google or FB having an app for employees to order food from the cafeteria as well as apps for internal tools/build pipelines/etc. While some POS apps like Square are in the app store there are others that are distributed through enterprise apps. It allows companies to push updates faster when/if something goes wrong. I also know (at least in the past) NetJets used enterprise apps for their pilots, the apps had the flight manual among other things if I remember correctly. Often it's custom or white labeled software that benefits from enterprise distribution. EDIT: Also if an organization is large enough TestFlight might not be suitable to cover everything they need. For example you might want nightly developer builds, weekly/milestone internal test builds, stagings builds, and then TestFlight and release. You can accomplish this with multiple apps that are never released (My App - Dev, My App - QA) so you can use TestFlight for each and then only release the production "My App" but that has some sharp edges and requires everyone be added to the Apple development team.
