QR-bill invoicing for transport companies in Sulgen: 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 QR-bill invoicing in Sulgen: what the law requires, what can be automated, and when to delegate.
Digitalising QR-bill invoicing: 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 Sulgen as everywhere.
For QR-bill invoicing, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.
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.
For QR-bill invoicing, the share of collections matched automatically is a metric worth watching: when it drops, it is almost always a matter of misused references.
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.
In an SME in Sulgen, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.

Outsource QR-bill 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 clear mandate agreement states who does what by when: document handover, posting deadlines, filing calendar, and responsibility for delays. A shared platform (same data, same document archive) between the company and its fiduciary eliminates binder ping-pong and duplicate entry.
Sulgen: what changes, what does not
Sole proprietorship, Sàrl or SA in Sulgen: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Thurgau.
Sulgen requires no special bookkeeping: the Code of Obligations applies at postal code 8583 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
What are the legal obligations for QR-bill 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 Sulgen: federal law applies.
Which social contributions does a Swiss employer pay?
AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Sulgen, family allowances follow the canton's rates.
Does MyFiducia.ai work for a business based in Sulgen?
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 Sulgen manages its documents, VAT and exports exactly as anywhere in Switzerland.
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 Sulgen as anywhere.
