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 20, of which eight are partners.


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 of about 570 independent accountants, lawyers and consultants dispersed across 770 offices in 123 countries. 27 000 employees are affiliated with the group.

Our services include auditing, tax advisory, accounting and payroll services, consulting, and legal services. Insolvency work and forensic accounting are also an important part of our services.

In January 2015, we joined the law firm Flattum and can now also offer legal assistance to both companies and individuals. Advokatfimaet Flattum is a member of the law association of Norway.
