Apple accounts and a workplace Mac?

You can setup an account for a company, just use a company e-mail address that isn't strictly your own (ideally, something generic like appleid@company) and fill out the correct fields on the sign-up section.

You can also use this account to join the developer program with Apple - although this might be what you meant anyway.

When signing up, I'd still use your name - this can easily be changed, but fill out the company details (and, I suppose, credit card).
