I presume they will out-source it to a third party, which sounds exactly like the sort of thing a business consultant would tell them to do.
Yes, and it's the sort of thing businesses do without thinking things through. Once you do this, you've lost control overt hat aspect of your business, especially if things go wrong you. I remember when setting up new computer systems that was the route I followed - spec, hardware, software, installation all through one source. It might be dearer than shopping around (but then again it might not), but if, say, the printers didn't work, then you just handed the problem to the single source so there was no toing and froing with the printer people blaming the software company and the software people blaming the printer people and so on. Or, if there were, it wasn't me having to sort it.
