[Koha] KOHA INTERGRATION

Hi team.. I am having a challenge. Am in a school library using KOHA but the directors want to have an integrated school management system including a library module. They are specifically concerned with being able to know the total value of the resources in the library. Is there a way I can defend myself and still have KOHA give them the opportunity to view to total value of library collection integrated into their school managememt system? Or are there ways of generating reports giving the total value of our library collection? Regards Steve.
