QR-bill invoicing for restaurants in Frauenfeld: rules, deadlines, best practice
Whether you run a Sàrl, an SA or a sole proprietorship in Frauenfeld, QR-bill invoicing eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.
Digitalising QR-bill 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.
For an SME in Frauenfeld, the real gain of digitalised QR-bill invoicing 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 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 Frauenfeld.
For a business in Frauenfeld, comparability over time beats sophistication: a chart stable for five years beats a “perfect” one rebuilt every year. Banks and the tax administration read year-on-year movements first.
QR-bills and friction-free collections
Reminders work best graduated: a neutral first reminder, a firm second, then formal notice — each generated from exact balances, never from memory.
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 QR-bill invoicing
Whether a business sits in Frauenfeld or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for QR-bill invoicing. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
Late books show from the outside: poorly calibrated tax instalments, provisional filings, slow answers to the bank. Staying current is also a matter of image.
Frauenfeld: what changes, what does not
Frauenfeld (postal code 8500, canton Thurgau) applies the same federal rules as the rest of the country: what changes in Frauenfeld are the cantonal counterparts — tax administration, compensation office, commercial register.
Federal deadlines do not move in Frauenfeld: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 8500 changes nothing about those rules, only the sender's address.
Frequently asked questions
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 Frauenfeld as anywhere.
Do you need a fiduciary for QR-bill invoicing, or can you do it yourself?
Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Frauenfeld.
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 Frauenfeld 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 Frauenfeld as everywhere in Switzerland.
