I am under the impression that this may have a great deal to do with the local government's laws about responsibility for what is said and claimed.
In the USA there is very little that can be done about someone's specious claims (like 'we have the experience to help you reduce your liability', when really their 'experience' involved working for a company that went out of business due to the expense of not reducing their liability) where in the EU and UK, such a claim may be likely to have some proof behind it, in the USA, if you asked to openly provide such proof could get you sued in a SLAPP type lawsuit.
So, in the USA, a lot of "entrepreneurs" [en-trap-a-newer] can start a company that basically pays your bills and charges a % for paying the bill and calling a contracted service company, after you call them (same call as if you had called the service company, only adding another layer of confusion and $ between the end user and end repair person). This is then called 'fleet management consultancy'.
I regularly see people who now claim "expert" whom their greatest expertness in the forklift industry was in being at a forklift company that had some success for which they were not responsible (an example would be that they had been in the accounting department at the time) yet now work that "success" to show they should be followed as experts in the field of forklift company management.
Where [in some places] they may be required to be able to prove their expertise, in the USA, they would only be required to prove they can hire an attorney to muddy the water enough so the question of their expertise does not get asked.
As far as I have seen (which may be a sort of 'pinhole' vision, forest for the trees and all that, from my position), "what kind of costs are charged" is based upon either a monthly prorate of what is basically an extended warranty or on what the actual charges by the contracted service company or dealership is charging and any added services delivered beyond the repair service (so if you wanted training [etc.], that would be figured, marked up and added in).
