Quality advice and maximum efficiency

Our accounting and tax office is situated in Ottignies – Louvain-la-Neuve, in the province of Walloon Brabant. It is close to the economic activities park of Wavre and covers the axis Brussels-Gembloux-Namur. Our team consists of about 10 employees.


Our activity started following the acquisition of a client portfolio (SME and company executives) by the thg. The establishment in Louvain-la-Neuve dates back to 2010. We moved into the AGC Glass building in 2013. This building is recognised for its architectural and environmental qualities. Our clients are mainly self-employed people, company executives, managers of SMEs and companies integrated in large international groups.


A guide for each moment

From the first draft of their financial plan, our clients can rely on us and our expertise. Going forward we support them in all their administrative, accounting and tax tasks.


What is our added value? Management advice and tax optimisation. We also strive to establish internal accounting procedures with our clients that optimise the automation of encoding. To that end, we cooperate with an information technology partner from the region. This approach allows the managers to have trustworthy financial information at any moment of the year. Consequence: the digitisation of invoices and other accounting documents allows the relevant services to have access to files remotely and at any time. This is real progress in terms of management and flexibility.


Our objective is simple: build a long-term relationship of trust with you, convince you that we are a reliable partner, bring you the advice needed for the good management of your company and of your estate as a whole.
