You cannot buy many (any ?) existing custom software that will run on an ipad Pro, but getting an app developed to run on one would be surprisingly easy. It is possible that some serious apps that can usefully be used in a mobile & remote mode will indeed develop iPad clients. CRM is certainly one that comes to mind.
I do know of a number of tracking and delivery apps specifically ported to run on an iPad - typically a cheap one not the Pro, but it's "proof of concept" rather than a specific example.
