Invoice scanning legal obligations in Trun: the practical guide
Invoice scanning legal obligations in Trun 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
Automation is judged on the exceptions: what happens when the document is unreadable, the supplier unknown, the amount divergent? A good tool isolates those cases and lets a human decide fast — precious for teams in Trun.
For invoice scanning, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.
Outsource invoice scanning or keep it in-house?
Outsourcing invoice scanning to a fiduciary frees up time and secures compliance; keeping it in-house preserves a continuous view and costs less in fees. The best answer is often hybrid: the company captures and digitises as it goes, the fiduciary supervises, closes the books and represents the company before the authorities.
A business in Trun can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — invoice scanning splits very well.
The Swiss legal frame for invoice scanning
Whether a business sits in Trun or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for invoice scanning. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
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
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.
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.
Trun: what changes, what does not
Working with a fiduciary from Trun no longer depends on geography: the documents of a business in Trun are shared online, while the canton Grisons keeps its own deadlines for the tax return.
Federal deadlines do not move in Trun: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 7166 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 Trun as anywhere.
Do you need a fiduciary for invoice scanning, 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 Trun.
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 Trun can therefore archive fully digitally.
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.
