E-invoicing for construction companies in Wilen (TG): rules, deadlines, best practice
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 Wilen (TG): what the law requires, what can be automated, and when to delegate.
Digitalising e-invoicing: what actually works
The classic digitalisation traps are avoidable: scanning without quality control (unreadable records), stacking disconnected tools (double entry in disguise), or neglecting access rights. One single flow from document to entry, with clear roles, beats five shiny apps.
For an owner in Wilen (TG), 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.
QR-bills and friction-free collections
Electronic invoicing keeps advancing: the Swiss Confederation requires it from its suppliers for contracts from CHF 5,000, and more and more large Swiss companies ask for structured e-invoices rather than PDFs. Getting equipped early beats improvising under a client's deadline.
Reference discipline remains: an invoice issued without a structured reference — or paid by a client who truncates it — becomes a manual case again. Coaching recurring clients and keeping your own outgoing payments clean keeps the automation rate at the top.
The Swiss legal frame for e-invoicing
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Wilen (TG) 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 e-invoicing run entirely on digital tools — no paper binder is required.
A well-structured SME chart of accounts
Nearly all Swiss SMEs rely on the standard SME chart of accounts (Sterchi/Käfer): classes 1 (assets) to 9 (closing), with revenue in class 3 and expenses in classes 4 to 6. Using this standard structure makes conversations with your fiduciary, auditor and tax administration far easier.
Suspense accounts (to clarify) are useful provided they are emptied monthly: a swelling “miscellaneous” account is the classic symptom of a chart that no longer fits the activity.
Wilen (TG): what changes, what does not
Sole proprietorship, Sàrl or SA in Wilen (TG): the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Thurgau.
Wilen (TG) requires no special bookkeeping: the Code of Obligations applies at postal code 9535 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 Wilen (TG) too.
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 Wilen (TG) as anywhere.
Does MyFiducia.ai work for a business based in Wilen (TG)?
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 Wilen (TG) manages its documents, VAT and exports exactly as anywhere in Switzerland.
