Bookkeeping for construction companies in Martigny: the practical guide

Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Martigny.

The Swiss legal frame for bookkeeping

Whether a business sits in Martigny or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for bookkeeping. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.

For bookkeeping, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.

Digitalising bookkeeping: what actually works

Artificial intelligence has changed the economics of bookkeeping: automatic invoice reading reaches recognition rates that make manual entry marginal, and posting suggestions learn from corrections. The accountant does not disappear — the job shifts from data entry to control and advice.

For an SME in Martigny, the real gain of digitalised bookkeeping shows day to day: no paper pile at month-end, VAT prepared continuously, and an owner reading today's figures rather than last quarter's.

A Swiss SME's accounting calendar

January: salary declaration to the compensation office and salary certificates. End of February, May, August, November: quarterly VAT returns (effective method), each to be filed and paid within 60 days after the quarter ends. Within six months of year-end: approved annual accounts. Then: the tax return under cantonal deadlines, with extensions possible.

An SME in Martigny that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and bookkeeping stops being a source of worry.

A well-structured SME chart of accounts

The test of a good chart of accounts is a single question: can the owner find the margins in three clicks? If not, the chart serves the tax office but not the business — even in Martigny.

In an SME in Martigny, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.

Martigny: what changes, what does not

Martigny (postal code 1906, canton Valais) applies the same federal rules as the rest of the country: what changes in Martigny are the cantonal counterparts — tax administration, compensation office, commercial register.

Federal deadlines do not move in Martigny: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1906 changes nothing about those rules, only the sender's address.

Frequently asked questions

Which documents should be prepared for the year-end closing?

Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Martigny: the CO dictates it, not the commune.

Does MyFiducia.ai work for a business based in Martigny?

Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Martigny manages its documents, VAT and exports exactly as anywhere in Switzerland.

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 Martigny too.

When must a business register for VAT?

As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in Martigny as everywhere in Switzerland.
