About
Founder and Managing Director of Rosengold & Schmuker Treuhand GmbH.

Great to have you here. I'm Ivan – and to me, a good fiduciary is above all someone you're happy to call. There are no silly questions with me, and nobody needs to be embarrassed about their shoebox of receipts.
Numbers are my craft, but you are at the centre: your business, your plans and whatever is giving you a headache right now. I listen, explain things clearly and tell you honestly where you stand – no jargon, no surprises.
I like making things simpler. That's why I work digitally, reply quickly and keep accounts, payroll and taxes off your plate, so there's more time for what really matters to you.
When I'm not reconciling balance sheets, you'll find me on the football pitch or travelling somewhere in the world. Football taught me that you only win as a team, and that's exactly how I see working with you.
Fancy a coffee? The first meeting is on me →
Values
Three principles you can rely on.
One dedicated contact, short lines of communication and answers you understand – no jargon.
Modern cloud accounting, digital receipts and automated bank reconciliation save time and money.
Deadlines and quality are non-negotiable. Discretion goes without saying.
Story
How my mother's craft became our company name.
My mother, Brigitte Schmuker, was a gilder. With fine gold leaf and endless patience she gilded picture frames by hand – frames that gave artworks their proper stage at gallery openings. She taught me that it is care in the smallest things that makes the whole shine.
Our company carries that attitude in its name: Rosengold for the warm glow of work done with care, Schmuker for the family it comes from. What applies to gilding applies to your accounts, payroll and taxes too: precision, patience and a watchful eye for every detail.
