Our business units

Having the right perspectives on business trends

Our five business units highlight some of the trends seen by our various businesses, along with insights from some of our clients.


Within Deloitte Accountancy we have two big offerings, the first is Deloitte Business Process Solutions where we serve larger Belgian and international companies. The second is Deloitte Private which serves more than 5000 family companies in Belgium. 

Digital technology is having a great effect on our industry and it will influence the way we work with our clients in the future. In cloud accounting, for example, we have been able to build a platform where the interaction between the involved parties has become more structured and transparent and we are able to quicker deliver relevant information to the business owners.

Audit & Risk Advisory

Companies and governments rely on Deloitte for a wide range of audit, risk management and advisory services. These services are delivered by people who know how to bundle complex skills to provide confidence to the capital markets and value to our clients. The practice counts more than 600 dedicated client service professionals who provide a full range of services to Belgian as well as international clients.

The biggest challenge, but also opportunity, that we face is the green paper lead by French commissioner Barnier. The mandatory firm rotation will change our way of working as we will need to end longstanding relationships with some of our audit clients, but it will also open up other opportunities for us. Data analytics and cyber security are expected to grow significantly in the future.

We help organisations build value by uncovering insights that create new futures and doing the hard work to improve performance. Delivering this kind of value requires a broad range of talent and capabilities – across human capital, strategy & operations and technology – and importantly, aligned to the unique needs of specific sectors, businesses and organisations.

The Consulting business is changing very rapidly and as a result we face two specific trends: the fact that we operate in a highly fragmented but consolidating market and we see the introduction of many new innovations, solutions and offerings.

Financial Advisory

Deloitte Financial Advisory is proud of the professionalism of our consultants who are selected with the utmost care. The FA team consists of experts with backgrounds in investment banking, broking, consulting, auditing and accounting. All our people have in-depth knowledge of their field, resulting from years of experience. 

The biggest challenge our clients face is sustainable growth. In the current economic climate growth is not obvious so they may need to look for growth opportunities through acquisitions or they have may need to refocus on their core business and divest non-core activities.

Tax & Legal

Deloitte offers clients a broad range of fully integrated tax and legal services. Our approach combines insight and innovation from multiple disciplines with business and industry knowledge to help your company excel globally.

The tax environment has changed a lot over the past years and has become very complex. Tax legislation keeps changing all the time and tax audits have increased. Nine out of ten of our clients have been audited by the tax authorities in the last three years.
