Answer 2

A book keeper would literally be about keeping the books it is really about data entry. An admin assistant is a broad term that would be akin to secretary in most contexts. Accounting assistant is similar to an admin assistant but to an accountant so would do some of what an admin assistant would do and some of a book keeper.
