I am not sure what central costs cover, I am translating a proposal for a business improvement and the submitting company states that they will cover Engineering and Central costs. What exactly does that include?
There are many references to "central costs" on the internet. The only one I found that might be a definition is this one: "Central costs... comprise corporate costs and central development, marketing and technical operations ...."
It's very general, however. If I were looking for specifics, I'd simply call the company and ask.
