About us

Revisjonsfirmaet Flattum & Co AS is a continuation of an audit firm founded by Sven Flattum in 1991. Since start-up we have expanded gradually and currently are a team of 21, of which seven are partners.


Our services include auditing, tax advisory, accounting, payroll services, consulting and forensic accounting

In January 2015, we entered into a partnership with the law firm Flattum and can now also offer legal assistance to companies and private individuals.

Our partners and staff have extensive experience in all industries and with enterprises of all sizes. Furthermore, we have substantial experience in working with international companies.

Our goal is to protect our clients' interests in the best way possible within the limits of the law. We make a point of having a stable and competent workforce on all projects.


We are a member of GGI, an international alliance that includes around 605 independent auditors, lawyers and consultants in 840 offices in 126 countries. 28,900 employees are associated with the alliance.
