This sounds about right to me. In particular, it tends to partiton the organization into (A) the people whose job it is to plug away at the ERP system (orders, invoices, tickets, etc), and (B) the people who actually do whatever it is that the company does.
(C) - License costs can also play into this partitioning.
Then you hope (and work to ensure) that the benefit achieved for B, by having consistent org-wide information systems to work from, is enough to cover the overheads of A and C.
