founded in 1963 when firms from the UK, Netherlands, Germany, US and Canada joined forces to share and expand their knowledge to better support clients. They were known as Binder Seidman International Group until 1973, when they adopted the name Binder Dijker Otte & Co: BDO.

They continued to build their international capabilities, growing the strong local roots that mean they now provide services to their clients in 144 countries. In 1988, they established a world wide structure and the BDO acronym was placed before each local member firm’s name. This, together with the introduction of a new logo and a consistent global brand, clearly demonstrated that the local expertise of their member firms was combined with the international expertise and strength of their international network.

Since then, their network has continued to transform in response to client needs, culminating in the change of their name in 2009 to simply BDO. Their move to a single global trading name demonstrates their commitment to service their clients and to compete successfully in their market on a multinational basis.

BDO is the world’s fifth largest accountancy network. They have an excellent partner to staff ratio, with 56,000 people working with their clients and offering challenging, ethical and practical advice from 1,264 offices in 144 countries.
