BDO Global

BDO (an acronym for Binder Dijker Otte) is an international professional services network of public accounting, tax, consulting and business advisory firms headquartered in Zaventem, Belgium. The network is coordinated by BDO Global Coordination B.V., a limited liability company incorporated in Belgium, while each BDO member firm is part of BDO International Limited, a UK company limited by guarantee.

BDO is the fifth-largest accounting network in the world, with global income of its member firms totalling US$ 15 billion in 2024. Each BDO member firm is an independent legal entity in its own country. The network was founded in 1963 as Binder Seidman International Group by firms from Canada, Germany, the Netherlands, the UK and the US. In 1973, the organisation adopted the name BDO, made up from the initials of the three founding firms: Binder (UK), Dijker (Netherlands) and Otte (Germany).
