Invoice scanning for the self-employed in Witterswil: the practical guide
Invoice scanning for the self-employed in Witterswil rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.
Digitalising invoice scanning: what actually works
Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Witterswil as everywhere.
An SME in Witterswil 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 invoice scanning.
The Swiss legal frame for invoice scanning
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Witterswil as anywhere.
The law also settles the form: accounts may be kept in a national language or in English, on paper or electronically (art. 957a para. 5 CO). That pragmatism lets invoice scanning run entirely on digital tools — no paper binder is required.
A well-structured SME chart of accounts
Shareholder current accounts demand strict hygiene: every private withdrawal documented, interest at the rates accepted by the tax administration, and a clean-up at closing.
For invoice scanning, a few well-chosen analytical accounts (by activity, by site) beat a forest of sub-accounts nobody ever reads.

Outsource invoice scanning or keep it in-house?
A good test before choosing: ask the fiduciary HOW it wants to receive the documents. A precise answer (formats, frequency, platform) says more than any brochure — including in Witterswil.
A business in Witterswil can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — invoice scanning splits very well.
Witterswil: what changes, what does not
Working with a fiduciary from Witterswil no longer depends on geography: the documents of a business in Witterswil are shared online, while the canton Solothurn keeps its own deadlines for the tax return.
Witterswil requires no special bookkeeping: the Code of Obligations applies at postal code 4108 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
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 Witterswil too.
How long must records related to invoice scanning 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 Witterswil can therefore archive fully digitally.
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 Witterswil.
Can invoice scanning 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 invoice scanning.
