HL BM IA without financial accounts?

Hey guys!! So basically for my HL BM IA, I'm doing it on a business that my mom works at. However, the business is private so I have no access to their financial info. I've already tried asking through my mom and my school but they rejected both requests :,). So my question is, is it possible to do fairly well in an HL BM IA without having a business's financial accounts?

Thanks in advance!
