Bookkeeping for SA companies in Frenkendorf without the stress: how it works

Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on bookkeeping in Frenkendorf: what the law requires, what can be automated, and when to delegate.

The Swiss legal frame for bookkeeping

In Switzerland, the duty to keep accounts stems from art. 957 ff. of the Code of Obligations. Legal entities (Sàrl, SA) and sole proprietorships with at least CHF 500,000 in revenue keep full accounts: balance sheet, income statement and notes. Below that threshold, a simplified record of income, expenses and assets is sufficient.

The good news: the Swiss frame is stable and predictable. Structure bookkeeping once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

Digitalising bookkeeping: what actually works

A serious accounting document archive links every record to its entry, timestamps versions and logs access — exactly what Swiss bookkeeping regulation expects from probative electronic retention. Chronological filing by financial year becomes an automatic by-product.

For bookkeeping, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.

Extensions exist and can be requested: cantonal deadlines for the tax return, deferral of the VAT filing on a reasoned request. But an extension does not stop interest: on VAT, default interest runs from the ordinary due date even when more time has been granted.

For bookkeeping, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.

A well-structured SME chart of accounts

Account labels deserve as much care as numbers: “Third-party fees” says nothing, “Fiduciary fees” and “IT fees” say everything. Meaningful labels cut posting errors and make dashboards readable without a glossary.

For bookkeeping, the right granularity is decisive: enough accounts to steer the business (margins by activity, expenses by nature), few enough that every entry finds its place without hesitation. The VAT accounts (input VAT, VAT due) deserve special care — they are the basis of the annual reconciliation.

Frenkendorf: what changes, what does not

Sole proprietorship, Sàrl or SA in Frenkendorf: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Basel-Country.

Frenkendorf requires no special bookkeeping: the Code of Obligations applies at postal code 4402 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

What are the legal obligations for bookkeeping in Switzerland?

The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Frenkendorf: federal law applies.

When is entry in the commercial register mandatory?

A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Frenkendorf too.

Can bookkeeping be automated with AI?

Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches bookkeeping.

What is the difference between a limited and an ordinary audit?

The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Frenkendorf as anywhere.
