Clear books.
Calm decisions.
KLAR keeps the accounting, taxes and payroll of Swiss firms in impeccable order — and explains every figure in plain language. That is what klar means.

What we keep in order
Four entries. Everything a Swiss firm has to file, close or pay.
Who we act for

Owner-led SMEs
Companies from two to fifty employees, across German-speaking Switzerland and beyond.
- Monthly payroll runs
- Board-ready reporting
- Audit liaison
Private clients
Households with property, portfolios, or a pension question that will not wait until retirement.
- Tax return & optimisation
- Pillar 2 & 3a planning
- Estates & inheritance
The mandate, over one year
One year. One thread. Four appointments it never misses.
The line running down this page is the same one that runs through every mandate. Each red mark is a quarter — and a deadline met.
Q1 · Jan – Mar
The closing
The prior year is closed and reconciled. Financial statements reach your board before the tax office writes to you.
Q2 · Apr – Jun
The filing
Returns filed — or extensions secured — ahead of every cantonal deadline. You never write to a tax office yourself.
Q3 · Jul – Sep
The review
Half-year figures against budget, provisional taxes checked, the forecast updated. Surprises are found here, not in December.
Q4 · Oct – Dec
The plan
Salaries declared, the coming year budgeted, reserves set — so January opens calmly, with nothing carried over.
The people who sign
Every closing carries a partner’s signature.
Twelve people, three partners, one office above the Talstrasse. When you call, the person who answers has seen your ledger.

Fees, before we begin
Printed here. Held to there.
Every mandate starts with a written fixed quote. If the scope changes, you hear it from us — never from the invoice.
All figures excl. VAT. Combined mandates are quoted as a single annual fixed fee, payable quarterly. Click a line for its footnote.

First consultation
The first hour is on us.
Bring the books as they are — a shoebox of receipts is fine. Within the hour you will know what is in order, what is missing, and what it will cost. In writing.
