Our Focus

We provide the distinct financial clarity you need to succeed. As a boutique partner, we offer a level of focus large firms cannot match. From precise business accounting and strategic financial planning to expert tax advice, we handle the complexities so you can drive your business forward.

At Sollberger KMU Treuhand, we provide more than just bookkeeping; we provide financial leadership. Led by Stefan Sollberger, our Winterthur-based firm supports companies with comprehensive accounting mandates, including quarterly reporting and controlling. We specialize in tax optimization—specifically regarding real estate capital gains—and offer rapid support for financial bottlenecks. From operational payroll management to strategic debt restructuring for private individuals, we act as your external financial department.

Our financial expertise is forged in the world’s most demanding environments. Stefan Sollberger has executed senior controlling and financial mandates for global industry leaders, including UBS, Swisscom, Siemens, and Alstom. We bring this same level of corporate precision and rigor to the accounting and tax management of your SME.
