Fiduciary firms in Switzerland, organized by region

Treuhandscout is a directory of Swiss fiduciary firms, grouped by region. We gather providers where businesses and individuals actually look for them, and describe in plain terms what each firm focuses on and where it's based. People rarely choose a fiduciary firm and usually keep it for years, often for the entire life of a company. Once you've handed over your bookkeeping, receipts and access credentials, you don't switch again lightly. That's exactly why the choice matters from the start. Proximity helps more than you'd think: a firm working in the same canton knows the relevant tax offices, the regional deadlines and local practice, and a face to face meeting is easier to arrange than a trip across the country.

What a fiduciary firm handles

The scope of work is broader than the term first suggests. Day to day bookkeeping is usually the core: recording receipts, keeping accounts, filing VAT returns. On top of that comes the year-end close with balance sheet and income statement, which for a corporation forms the basis for the tax return. Many offices also take on payroll accounting, including the settlements with AHV, the pension fund and accident insurance, plus withholding tax and salary certificates. On the tax side, services range from the annual return for the company and its owner to planning bigger steps, such as a start-up, a succession or a change of legal form. Some providers advise more broadly, from liquidity planning to retirement provision. Which of these services you need has a big say in which firm is the right fit.

How to choose the right fiduciary firm

Start with an initial meeting, which many offices offer for free. Describe your situation openly and pay attention to whether you're actually listened to and whether the answers stay clear instead of drowning in jargon. Ask specifically about experience in your industry: a restaurant does its accounts differently than a construction company or a medical practice, and a firm that knows the daily reality of your business will save you explanations and mistakes. Sort out the fee model early. Some firms bill by time and hourly rate, others work on a monthly flat fee, and both approaches have their place as long as it's clear what's included and what costs extra. Get a written quote before you begin. Talk about software too: a firm working with bexio, Abacus or a comparable system can share access with you, so you can upload receipts yourself and check the numbers whenever you like. You'll recognize good cooperation by prompt answers to your questions, the same contact person staying with you over the years, and no surprises at year-end.
