Invoice scanning guide in Quarten: rules, deadlines, best practice
Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Quarten.
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 Quarten.
For an SME in Quarten, the real gain of digitalised invoice scanning 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.
QR-bills and friction-free collections
Instalments and partial payments are handled cleanly with distinct references per tranche: each collection finds its share, and the remaining balance stays correct at all times.
For an SME in Quarten, receivables are an asset to manage: a weekly ageing balance, graduated reminders and a provision for doubtful cases — invoice scanning provides the numbers, discipline does the rest.
The Swiss legal frame for invoice scanning
For an owner in Quarten, the question is never “do we need accounts?” but “at what level of detail?”. The CO sets the floor; the bank, the tax office and the shareholders set the rest.
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.
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.
Quarten: what changes, what does not
Working with a fiduciary from Quarten no longer depends on geography: the documents of a business in Quarten are shared online, while the canton St. Gallen keeps its own deadlines for the tax return.
Federal deadlines do not move in Quarten: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 8877 changes nothing about those rules, only the sender's address.
Frequently asked questions
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 Quarten can therefore archive fully digitally.
Which documents should be prepared for the year-end closing?
Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Quarten: the CO dictates it, not the commune.
Does MyFiducia.ai work for a business based in Quarten?
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 Quarten manages its documents, VAT and exports exactly as anywhere in Switzerland.
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 Quarten.
