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

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

Digitalising e-invoicing: what actually works

Accounting digitalisation always follows the same path: capture documents at the source (photo or PDF upload), let automatic recognition extract supplier, amount, date and VAT, approve the proposed entries, then archive each document linked to its entry. Every step removes a re-keying — and therefore an error source.

An SME in Wimmis that digitalises gains owner time first: less filing, fewer “where is that receipt?” questions, more attention to the trade — that is the real return of e-invoicing.

Outsource e-invoicing or keep it in-house?

Splitting roles clearly avoids duplication: the company captures documents and approves payments; the fiduciary checks postings, closes the year and defends the file before the authorities. Each side does what it does best — and nobody keys the same invoice twice.

A business in Wimmis can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — e-invoicing splits very well.

QR-bills and friction-free collections

Clear payment terms, a visible due date, exact details: half of late payments come from ambiguous invoices, not bad payers — the finding holds in Wimmis too.

A business in Wimmis can collect by QR-bill even without sophisticated software: what matters is that every incoming payment finds its invoice, manually or automatically.

The Swiss legal frame for e-invoicing

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Wimmis with a clean audit trail sails through these exercises.

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.

Wimmis: what changes, what does not

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

Federal deadlines do not move in Wimmis: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 3752 changes nothing about those rules, only the sender's address.

Frequently asked questions

How long must records related to e-invoicing be kept?

Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Wimmis can therefore archive fully digitally.

What are the legal obligations for e-invoicing 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 Wimmis: federal law applies.

What is simplified bookkeeping and who can use it?

Sole proprietorships and partnerships under CHF 500,000 of revenue may limit themselves to recording income, expenses and assets (art. 957 para. 2 CO). Once over the threshold — or upon founding a Sàrl or an SA — full accounts with balance sheet, income statement and notes become mandatory. The CHF 500,000 threshold is assessed the same way in Wimmis.

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 Wimmis: the CO dictates it, not the commune.
