E-invoicing for physiotherapy practices in Quarten: what every SME should know

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 Quarten.

Digitalising e-invoicing: what actually works

Automation is judged on the exceptions: what happens when the document is unreadable, the supplier unknown, the amount divergent? A good tool isolates those cases and lets a human decide fast — precious for teams in Quarten.

For an owner in Quarten, a dashboard only has value if the data is fresh: automating data entry means, first of all, buying up-to-date information about your own business.

The Swiss legal frame for e-invoicing

Responsibility for the books is personal: in an SA, organising the accounting is one of the board's non-transferable duties (art. 716a CO); in a Sàrl, the managing directors carry the same duty. Outsourcing the execution never transfers that underlying responsibility, including for a company based in Quarten.

Art. 957a CO requires complete, truthful and systematic recording of transactions, each entry backed by a supporting document. For e-invoicing, that means in practice: no movement without a receipt, and an audit trail that can be reconstructed at any time — including during a VAT or AHV inspection.

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 e-invoicing, a few well-chosen analytical accounts (by activity, by site) beat a forest of sub-accounts nobody ever reads.

QR-bills and friction-free collections

Instalments and partial payments are handled cleanly with distinct references per tranche: each collection finds its share, and the remaining balance stays correct at all times.

For an SME in Quarten, receivables are an asset to manage: a weekly ageing balance, graduated reminders and a provision for doubtful cases — e-invoicing provides the numbers, discipline does the rest.

Quarten: what changes, what does not

Sole proprietorship, Sàrl or SA in Quarten: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton St. Gallen.

Federal deadlines do not move in Quarten: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 8877 changes nothing about those rules, only the sender's address.

Frequently asked questions

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 Quarten too.

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 Quarten: the CO dictates it, not the commune.

Effective VAT method or net tax rate: how to choose?

The effective method deducts actual input VAT and files quarterly; the net tax rate method applies a flat industry rate to turnover, semi-annually, with no separate input VAT deduction. The flat rate suits low-cost structures; as investments grow, the effective method usually wins again. The choice rests on the company's own figures, in Quarten as anywhere.

What are the current Swiss VAT rates?

Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Quarten.
