The Costmasters story

After seven years in Finance with international companies (Darty and L'Oréal), Charles Markowicz founded Costmasters in 1994. Over the years, this accounting and tax firm has developed two areas of expertise which are reflected in the high-performance services offered to SMEs active in Belgium.

 

. Tax and accountancy  

Accounting and taxation form the first axis of services to businesses, companies and non-profit organizations. Beyond relieving them of legal obligations (VAT, tax declarations, etc.), the firm's employees provide knowledge and expertise, particularly in tax matters.

 

. Part-time virtual chief financial officer

Most SMEs simply cannot afford a CFO, but they would like to benefit from such skills, even if only on a small scale. This is why we have developed VCFO, a ‚Äúvirtual‚ÄĚ CFO service on a very part-time basis, from as little as two hours per month.

 

. Expert witness or technical advisor

Our second service axis is the conflict resolution center, where we respond to the concerns of individuals, companies and courts with regard to accounting and financial matters. Since 1996 we have acted as legal expert for the Belgian courts and technical adviser for individuals or companies involved in conflicts. We also act as certified mediators trained in civil and commercial mediation. We promote amicable resolutions without neglecting the primary interests of our clients.

Are you experiencing an accounting or tax problem, whether one-off or structural? Would you like to strengthen your management, take a step back? Are you in the grip of a conflict with a shareholder, supplier or ex-partner, that you would like to resolve in your best interests?

Each situation is unique in the matters we deal with, and your questions need specific answers. Don't hesitate to contact us.

Testimonies

Tax and Accountancy

After 20 years of working at Larcier, I have visited and known many tax firms. Yet I remember one and only one . . . Costmasters! Since then I have given them my business without the slightest hesitation, and the service I get is the best there is! I can really move ahead with confidence today.

Dear Expert, Thank you for your diligence and dedication. I hope to have the opportunity (and why not several times?) to meet you again.

Hello Mr. Markowicz, Thank you for your visit yesterday. As a result, we managed to reach an agreement on the value of our company's shares. All I have to do now is write a shareholders' agreement.
J. D.
Business owner
I would like to take this opportunity to thank the expert for his action as an amicable mediator, not only in the context of the valuation of the company's shares, which was his mission, but also in his assertion to the parties of their interest in seeking a global solution.

C. B.
Lawyer
I wanted to personally thank you for your handling of this affair. I very much appreciated your impartiality in the management of the exchanges. At the beginning I was very worried about the nationalism I had encountered in Spain last year. Thank you warmly for your professionalism.

G. B.
CFO
Thank you very much for your work as expert. I would like to take this opportunity to thank you for the quality of your work in this matter. Take good care and all the best for you.
