About us
Masters in the art of accounting.
Greenpen is a growing, dynamic practice with an authentic nature and close relationships with its clients — offering not only a wide range of quality services, but an entire experience.
Our story
Mervitz & Malan, now Greenpen.
In 2022, Mervitz & Malan began working under the Greenpen name. While the name changed, our core beliefs did not: we remain committed to providing the same quality service clients have come to expect.
The updated brand reflects our evolution and growth, along with our continued commitment to being an authentic blend of professional standards, ethical values and best practice principles.
Our offices are in Ballito on the Dolphin Coast and in Brooklyn, Pretoria, where the practice has been located since the early 1990s.
The art of accounting
“As an artist hones in on their subject, with eyes of experience we hone in on the art of accounting.”
Our name and philosophy come from the idea that accounting, done well, is a craft. We embrace creativity and originality when creating solutions, and we believe in improving efficiency and effectiveness while keeping to the highest standards.
We look closely, analyse and connect the dots — and we are committed to working with you until the right solution is found.
